Comparison requires valid measurement: Rethinking attack success rate comparisons in AI red teaming
比较需要有效的测量:重新思考人工智能红队中攻击成功率比较
Abstract 摘要
We argue that conclusions drawn about relative system safety or attack method efficacy via AI red teaming are often not supported by evidence provided by attack success rate () comparisons.
We show, through conceptual, theoretical, and empirical contributions, that many
conclusions are founded on apples-to-oranges comparisons or low-validity measurements.
Our arguments are grounded in asking a simple question: When can attack success rates be meaningfully compared?
To answer this question, we draw on ideas from social science measurement theory and inferential statistics, which, taken together, provide a conceptual grounding for understanding when numerical values obtained through the quantification of
system attributes can be meaningfully compared.
Through this lens,
we articulate conditions under which s can and cannot
be meaningfully compared.
Using jailbreaking as a running example, we provide examples and extensive discussion of apples-to-oranges comparisons and measurement validity challenges.
我们认为,通过人工智能红队测试得出的关于相对系统安全性或攻击方法有效性的结论,往往没有得到攻击成功率( )比较所提供的证据支持。通过概念、理论和实证贡献,我们表明许多结论是基于苹果对橙子的比较或低效度的测量。我们的论点基于一个简单的问题:攻击成功率何时可以有意义地比较?为了回答这个问题,我们借鉴了社会科学测量理论和推断统计学的思想,这两者结合起来为理解通过系统属性量化获得的数值何时可以有意义地比较提供了概念基础。通过这个视角,我们阐述了 可以和不可以有意义地比较的条件。以越狱为示例,我们提供了苹果对橙子的 比较和测量效度挑战的实例和广泛讨论。
1 Introduction 1 引言
AI red teaming, adversarial testing, jailbreaking, and related approaches are among the most widely used methods for probing generative AI (genAI) systems for undesirable behaviors.111We use “undesirable system behaviors”
as a catch-all for the types of behaviors these approaches aim to elicit.
我们用“不受欢迎的系统行为”来泛指这些方法旨在引发的行为类型。
AI 红队测试、对抗性测试、越狱测试和相关方法是目前探测生成式 AI(genAI)系统不良行为最广泛使用的方法之一。 1
We refer to all of these approaches generically as (AI) red teaming throughout this paper.
These approaches can help identify genAI system vulnerabilities; detect memorization of intellectual property; and assess how well safety alignment prevents violations of model providers’ code of conduct policies prohibiting system use for exploitative, abusive, and otherwise harmful aims (FMF, 2024; Llama Team, 2024; OpenAI, 2023; Nasr et al., 2023; Tamkin et al., 2021; OpenAI, 2024; Cooper et al., 2025).
在本论文中,我们将所有这些方法统称为(AI)红队测试。这些方法有助于识别 genAI 系统漏洞;检测知识产权记忆;并评估安全对齐如何防止违反模型提供者行为准则政策,这些政策禁止系统用于剥削、虐待或其他有害目的(FMF,2024;Llama 团队,2024;OpenAI,2023;Nasr 等人,2023;Tamkin 等人,2021;OpenAI,2024;Cooper 等人,2025)。
While AI red teaming has traditionally been
used to obtain qualitative information about system vulnerabilities and effective attack vectors (Ahmad et al., 2024; Nasr et al., 2025), it is increasingly used to obtain quantitative information, often in the form of attack success rates.
Attack success rates (s)—i.e., the fraction of attacks that were judged successful in eliciting undesirable behaviors—are routinely used as measurements for making comparative claims about whether one system is more vulnerable than another, whether mitigation efforts improved system safety, and whether some attack methods (e.g., jailbreaking methods) are superior to others (Ganguli et al., 2022; Chu et al., 2024; Tedeschi et al., 2024; Xie et al., 2024; Wei et al., 2023). In this paper, we argue the position that comparisons often fail to provide a sound evidentiary basis for conclusions about relative system safety or attack method efficacy.
虽然人工智能红队测试传统上用于获取系统漏洞和有效攻击向量的定性信息(Ahmad 等人,2024;Nasr 等人,2025),但它越来越多地用于获取定量信息,通常以攻击成功率的形式呈现。攻击成功率( s)——即被判定为成功引发不良行为的攻击比例——被常规用作衡量指标,用于比较一个系统是否比另一个系统更脆弱、缓解措施是否提高了系统安全性,以及某些攻击方法(例如越狱方法)是否优于其他方法(Ganguli 等人,2022;Chu 等人,2024;Tedeschi 等人,2024;Xie 等人,2024;Wei 等人,2023)。在本文中,我们主张 比较往往无法为关于相对系统安全性或攻击方法有效性的结论提供可靠的证据基础。
Specifically, we focus on the simple-to-pose—but not-so-simple-to-answer—question: When can attack success rates be meaningfully compared as reflections of relative system safety or attack method efficacy?
To begin, we describe how comparisons can be viewed as evaluative or inferential claims that compare estimands on the basis of evidence provided by observed estimates (namely, s). We demonstrate how s can be viewed as estimates of population parameters (estimands) defined in terms of threat models that specify distributions over attacks and the concept(s) necessary for determining attack success.
Using this framing, we provide a two-part sufficient condition
for when s can be meaningfully compared.
First, we need conceptual coherence: It should be meaningful to compare the population parameters. If comparing these parameters would not provide sound evidence of a claim regarding relative system safety or attack method efficacy, then comparing s—which are simply estimates of those parameters)—is no more meaningful.
Second, we need measurement validity: The s should be valid measurements of the population parameters.
具体来说,我们关注一个简单提出但不易回答的问题:在何种情况下,攻击成功率可以被有意义地比较,以反映相对系统安全性或攻击方法的有效性?首先,我们描述了如何将 比较视为基于观察估计(即 )所提供的证据来比较估计量(estimands)的评估性或推断性声明。我们展示了如何将 视为基于威胁模型定义的总体参数(estimands)的估计量,这些威胁模型指定了攻击的分布以及确定攻击成功所必需的概念。在这个框架下,我们提供了一个两部分的充分条件,用于判断何时 可以被有意义地比较。首先,我们需要概念一致性:比较总体参数应该是有意义的。如果比较这些参数不能为相对系统安全性或攻击方法有效性提供可靠的证据,那么比较 (这些参数的简单估计量)也就没有更多意义。其次,我们需要测量有效性: 应该是总体参数的有效测量。
Paper outline.
To begin, we motivate our central arguments by drawing parallels between comparisons and more established practices of comparing observed outcomes in experimental studies of clinical treatment superiority (Section 2). Having provided the basic intuition, we then apply the joint lenses of social science measurement theory and inferential statistics to instantiate a common quantitative AI red teaming approach—specifically, jailbreaking—in a formal measurement theory framework (Section 3)
This allows us to characterize s as estimates (measurements) of precisely-defined estimands (population parameters), and to formally state a two-part sufficient condition for when s can be meaningfully compared: conceptual coherence and measurement validity. We then illustrate some common failures of conceptual coherence (Section 4) and measurement validity (Section 5), drawing on examples from well-cited published jailbreaking studies and providing additional empirical and theoretical analyses. We conclude with recommendations for improving quantitative AI red teaming practices for jailbreaking and beyond. In the interest of focusing the main paper text on our position, we defer a broader discussion of related work to Appendix A.
论文大纲。首先,我们通过比较 与临床治疗优势实验研究中更成熟的观察结果比较实践来论证我们的核心论点(第 2 节)。在提供基本直觉后,我们运用社会科学测量理论与推断统计学的联合视角,将一种常见的定量 AI 红队方法——具体而言是越狱攻击——实例化于形式测量理论框架中(第 3 节)。这使我们能够将 描述为对精确定义的估计量(总体参数)的估计(测量),并正式陈述 可以有意义比较的两部分充分条件:概念一致性和测量有效性。接着,我们通过引用广泛发表的越狱攻击研究中的例子,在第 4 节和第 5 节分别说明概念一致性和测量有效性的常见失败,并提供额外的实证和理论分析。最后,我们提出改进越狱攻击及更广泛的定量 AI 红队实践的建议。 为了使主要论文文本集中于我们的立场,我们将相关工作更广泛的讨论推迟到附录 A。
2 Background: Descriptive, Inferential, and Evaluative Claims
2 背景:描述性、推断性和评价性声明
To answer the question of when attack success rates can be meaningfully compared, we must first understand what is being asked. Consider a hypothetical scenario in which a research team is comparing a new jailbreaking method (jailbreak ) to an existing competing method (jailbreak ). The team tests the two methods on a genAI system, , obtaining s of for their method and for the competing method.
What can we conclude on the basis of these results?
为了回答攻击成功率何时可以有意义地进行比较的问题,我们必须首先理解所问的是什么。考虑一个假设场景,其中研究团队正在比较一种新的越狱方法(越狱 )和一种现有的竞争方法(越狱 )。该团队在 genAI 系统 上测试这两种方法,为其方法获得 的 ,而竞争方法获得 。根据这些结果,我们可以得出什么结论?
There is no doubt that, as numbers, —i.e., jailbreak attacks were judged as succeeding more often than jailbreak attacks.
This is a descriptive statement summarizing the outcomes of the specific sets of attacks, system configurations, system outputs, and determinations of success.
But can we conclude from these results that jailbreak is generally “superior” to jailbreak ? Such a conclusion would constitute an evaluative claim.
毫无疑问,作为数字, —即,越狱 攻击被认为比越狱 攻击更频繁地成功。这是一个总结特定攻击集、系统配置、系统输出和成功判定的描述性陈述。但我们能否从这些结果中得出结论,认为越狱 通常“优于”越狱 ?这样的结论将构成一个评价性主张。
This question is akin to, but
in certain ways more complex than,
familiar questions arising in experimental studies of medical treatment superiority.
Consider a hypothetical study where researchers conduct a randomized controlled trial in which patients are randomized to either the standard of care () or a new treatment (), and then are followed for a 3-year period to assess their survival.
For patients in the control group, we observe a 3-year survival rate of , compared to for patients in the treatment group. Can we conclude that the new treatment is therefore “superior”?
Once again, there is no doubt that, as numbers, —i.e., in the study, the 3-year survival rate was higher for patients randomized to the new treatment than the 3-year survival rate for patients randomized to the control group receiving the standard of care.
This is a descriptive claim about the observed outcomes involving the study participants.
这个问题类似于,但在某些方面比实验研究中常见的关于医疗治疗效果优越性的问题更为复杂。考虑一项假设性研究,研究人员进行了一项随机对照试验,将患者随机分配到标准护理( )或新疗法( ),然后随访 3 年以评估其生存情况。对于对照组患者,我们观察到 3 年生存率为 ,而治疗组患者的 3 年生存率为 。那么,我们能得出结论说新疗法因此“更优越”吗?再次强调,毫无疑问,作为数字, ——即在该研究中,被随机分配到新疗法组的患者的 3 年生存率高于被随机分配到接受标准护理的对照组患者的 3 年生存率。这是一个关于研究参与者观察结果的描述性声明。
However,
when asserting that the treatment is superior, we are not making a narrow claim referring only the observed outcomes.
Rather, we are (at least implicitly) making an inferential claim that generalizes from the study participants to a broader patient population. In the language of inferential statistics, our claim rests on using and as estimates to make inferences about estimands (population parameters) and , where and denote the -year survival outcomes under the new treatment and the standard of care, respectively, and the expectation is taken over the patient population to which the conclusions are intended to generalize. At a minimum, we would want to conduct a hypothesis test to assess whether the findings are statistically significant.
然而,当我们断言处理方法更优越时,我们并非仅指仅限于观察到的结果。相反,我们(至少隐含地)作出了一个从研究参与者推广到更广泛患者群体的推断性声明。在推断统计学的语言中,我们的声明基于使用 和 作为估计值来对估计量(总体参数) 和 进行推断,其中 和 分别表示新治疗和标准护理下的 年生存结果,并且期望是对结论旨在推广的患者群体进行计算。至少,我们希望进行假设检验以评估研究结果是否具有统计学意义。
But additionally, since our goal is to assess whether the new treatment is “superior” to the standard of care, it is equally important to ask whether the population parameters, and , defined in terms of 3-year survival rates are appropriate indicators of superiority. What about considerations such as side effects? Or, if we interpret superiority even more broadly, what about treatment costs, and accessibility? Concluding that a treatment is superior on the basis of the inferential claim that is an evaluative claim. The soundness of this claim rests not only on the evidence that the observed outcomes carry about our estimands, but also on the extent to which the estimands capture meaningful notions of “treatment superiority.” In the next section, we will discuss how social science measurement theory offers a framework for formally interrogating how ambiguous, even contested, concepts such as system safety and treatment superiority are defined and measured.
但此外,由于我们的目标是评估新疗法是否“优于”标准治疗,因此同样重要的是要询问以 3 年生存率定义的总体参数 和 是否是优越性的适当指标。那么副作用等考虑因素呢?或者,如果我们更广泛地解释优越性,那么治疗成本和可及性又如何呢?基于 的推断性主张得出治疗是优越的结论。这一主张的合理性不仅取决于观察到的结果关于我们的估计量所携带的证据,还取决于估计量捕捉到“治疗优越性”这一有意义概念的程度。在下一节中,我们将讨论社会科学测量理论如何提供一个框架,以正式地探究诸如系统安全性和治疗优越性等模糊甚至有争议的概念是如何被定义和测量的。
Takeaways for AI red teaming. As will become clear in subsequent sections, just as claims about treatment superiority are both inferential and evaluative—i.e., they concern whether a study provides sufficient evidence to draw conclusions and make evaluative judgments beyond the study participants—claims made based on comparisons are also inferential and evaluative. The treatment superiority example highlights that, when making inferential or evaluative claims, it is not the observed 3-year survival rates that are being compared, but rather the estimands that we believe reflect treatment superiority. Likewise, with AI red teaming, we should not think of ourselves as “comparing s”—but instead as relying on s as estimates
of quantities we believe reflect system safety or attack method efficacy. We are comparing estimands via evidence provided by observed estimates.
针对 AI 红队测试的启示。正如后续章节将明确说明的,关于治疗优势的声明既是推论性的也是评估性的——也就是说,它们涉及研究是否提供了足够的证据来得出结论并对研究参与者之外的事项做出评估判断——基于 比较的声明同样是推论性和评估性的。治疗优势的例子突显了,在做出推论性或评估性声明时,被比较的不是观察到的 3 年生存率,而是我们相信反映治疗优势的估计量。同样地,在 AI 红队测试中,我们不应将自己视为“比较 s”——而应将 s 视为估计量,这些估计量反映了我们认为反映系统安全性或攻击方法有效性的数量。我们通过观察估计量提供的证据来比较估计量。
This means that having comparable estimands is a necessary condition for meaningful comparisons in AI red teaming. We call this condition conceptual coherence. To understand this condition, suppose that in the treatment superiority example, the researchers had compared the 3-year survival rate under the standard of care (control) to the 2-year survival rates under the new treatment. Then even if the sample size was sufficiently large to conclude the difference is statistically significant, and even if we believe that survival is a good indicator of treatment superiority, we would dismiss the evaluative claim that the new treatment is superior to the standard of care as being grounded in the apples-to-oranges comparison of to . This scenario may seem unlikely to arise in practice, and indeed in any reasonable medical study it would not. But, as we show in §4, incongruent estimands commonly arise in comparisons in AI red teaming studies. Reflecting on this example highlights another key point: meaningful comparisons rely on more than simply accounting for sampling variation of estimates through confidence intervals and hypothesis tests (Cooper et al., 2021; Hayes et al., 2025a). Indeed, we are primarily concerned with validity issues (bias and systematic mismeasurement) not simply reliability issues (sampling variation).
这意味着,在 AI 红队中,具有可比的估计指标是进行有意义的比较的必要条件。我们将此条件称为概念一致性。为了理解这个条件,假设在治疗优势的例子中,研究人员将标准护理(对照组)下的 3 年生存率与新型治疗下的 2 年生存率进行了比较。那么,即使样本量足够大,足以得出差异具有统计学意义的结论,即使我们认为生存率是治疗优势的良好指标,我们也会认为“新型治疗优于标准护理”的评估主张是基于苹果与橙子的比较( 与 ),从而将其视为无效。这种情况在实践中似乎不太可能发生,实际上在任何合理的医学研究中都不会发生。但是,正如我们在§4 中所示,不一致的估计指标在 AI 红队研究中的比较中普遍存在。 回顾这个例子突显了另一个关键点:有意义的比较不仅依赖于通过置信区间和假设检验来计算估计值的抽样变化(Cooper 等人,2021 年;Hayes 等人,2025a 年)。实际上,我们主要关注的是有效性问题(偏差和系统性测量误差),而不仅仅是可靠性问题(抽样变化)。
3 Attack Success Rates as Measurements
3 攻击成功率作为测量指标
We now describe how ideas from social science measurement theory provide a language for describing the connections between measurements (e.g., s) and the concepts they are intended to reflect (e.g., safety, vulnerability, efficacy).
For concreteness, we focus on jailbreaking, though the ideas are broadly applicable to s obtained via other AI red teaming approaches. We focus on the setting in which s are most commonly reported—
where humans or “red models” interact with genAI systems through prompting222Measurement theory is also helpful in understanding other types of attacks, such as those that rely on access to model weights or fine-tuning APIs. However, such attacks require a different setup, so we do not cover them.
测量理论也有助于理解其他类型的攻击,例如那些依赖于访问模型权重或微调 API 的攻击。然而,此类攻击需要不同的设置,因此我们不予涵盖。
我们现在描述社会科学测量理论中的思想如何为描述测量(例如, s)与其意图反映的概念(例如,安全性、漏洞、功效)之间的联系提供一种语言。为了具体说明,我们以越狱为例,尽管这些思想广泛适用于通过其他人工智能红队方法获得的 s。我们关注的是 s 最常报告的设置——人类或“红模型”通过提示 2 与生成式 AI 系统交互。 (via a user interface or API) to try to elicit undesirable behaviors.

Given a set of base harmful prompts, , jailbreak attacks aim to get systems to comply with harmful requests by transforming the base prompts (e.g., by concatenating a suffix such as “Begin your answer with ‘Sure, here’s’", or mapping to a Base64 encoding), or by perturbing the system configuration (e.g., by modifying the system prompt or decoding scheme) Andriushchenko et al. (2024); Liu et al. (2024); Mehrotra et al. (2024); Wei et al. (2023); Nasr et al. (2023, 2025). Attack success is determined by a judge, , which indicates whether system response meets the criteria for attack success with respect to prompt . could reflect human determination, where one or more humans determine attack success; alternatively could be a “red model” such as a simple substring matching function (Zou et al., 2023) or a judge system following the LLM-as-a-judge paradigm (Gu et al., 2024; Perez et al., 2022). We use , , and interchangeably throughout.
给定一组基础有害提示, ,越狱攻击旨在通过转换基础提示 (例如,通过添加后缀“以‘Sure, here’s’开头回答”,或映射到 Base64 编码),或通过扰动系统配置 (例如,通过修改系统提示或解码方案)来使系统遵从有害请求。Andriushchenko 等人(2024);Liu 等人(2024);Mehrotra 等人(2024);Wei 等人(2023);Nasr 等人(2023,2025)。攻击成功由裁判 判定,该裁判表明系统响应 是否满足针对提示 的攻击成功标准。 可能反映人类判定,即一个或多个人类判定攻击成功;或者 可能是一个“红模型”,例如简单的子串匹配函数(Zou 等人,2023)或遵循 LLM 作为裁判范式的裁判系统(Gu 等人,2024;Perez 等人,2022)。我们在全文中交替使用 、 和 。

Conceptualizing what s are measuring. In the language of measurement theory, the description of jailbreaking provided above describes the operationalized jailbreaking activity: it defines the measurement instrument that will be applied to obtain measurements (s) of concepts of interest (such system safety or jailbreak efficacy). Missing from this description is a specific articulation of what, precisely, we are measuring—i.e., what are s measurements of? It may feel rather backwards to ask what is being measured after already specifying how we are measuring it, but this is precisely the issue at the heart of current AI red teaming practices: what is being measured is often left under-conceptualized, with studies jumping quickly from under-specified concepts like “safety” to jailbreaking methods, datasets of harmful prompts, judge systems, and an array of reported s. That said, some studies do at least partially specify what is being measured (e.g., Wei et al., 2023; Yu et al., 2024; Chu et al., 2024).
理解 所测量的概念。在测量理论的语言中,上述对越狱的描述描述了操作化的越狱活动:它定义了将应用于获取目标概念(如系统安全或越狱效能)测量值( )的测量工具。这种描述中缺失的是对所测量内容的具体阐述——即 的测量具体测量的是什么?在已经明确测量方法之后,询问被测量内容似乎有些本末倒置,但这恰恰是当前人工智能红队实践中核心的问题:被测量的内容往往缺乏明确的概念化,研究迅速从“安全”等未明确的概念跳转到越狱方法、有害提示数据集、裁判系统以及各种报告的 。尽管如此,一些研究至少部分地明确了被测量的内容(例如,Wei 等人,2023;Yu 等人,2024;Chu 等人,2024)。
In measurement theory, concept conceptualization, also termed systematization in recent work on genAI evaluation Wallach et al. (2025), is one of three core processes linking between measurements and the concept of interest.
Figure 1 instantiates jailbreaking in a formal measurement theory framework, in which s are viewed as measurements arising from the execution of a jailbreaking protocol (operationalized activity) to measure attributes of a system (estimands), defined through a probabilistic threat model (systematized activity) that formalizes the attack goals (background activity). These four levels are connected via three processes: systematization, operationalization, and execution.
This representation builds on recent work adapting the framework of Adcock and Collier (2001)333Adcock and Collier (2001) represent measurement as moving from a “background concept” to measurement through the processes of
conceptualization (what we call systematization), operationalization, and application (what we call execution). Conceptualization is the process of precisely defining what we are measuring. Complex concepts such as safety and efficacy are background concepts that encompass a “broad [and often conflicting] constellation of meanings and understandings” (Adcock and Collier, 2001). In order to pose the question of how well s reflect concepts like safety and efficacy, we need to move from background concepts to systematized concepts: precise articulations of which of the many possible meanings and understandings we are targeting. Appendix B provides additional background on measurement theory.
Adcock 和 Collier(2001)将测量视为从“背景概念”转变为通过概念化(我们称之为系统化)、操作化和应用(我们称之为执行)的过程来实现。概念化是精确定义我们正在测量的内容的过程。安全性和有效性等复杂概念是背景概念,它们包含“广泛[且通常相互冲突]的意义和理解组合”(Adcock 和 Collier,2001)。为了提出 如何反映安全性和有效性等概念的问题,我们需要从背景概念转向系统化概念:即精确阐述我们针对的是众多可能的意义和理解中的哪些。附录 B 提供了关于测量理论的更多背景信息。
在测量理论中,概念概念化,近期在关于生成式 AI 评估的文献中 Wallach 等人(2025)也称之为系统化,是连接测量与目标概念的三种核心过程之一。图 1 在形式化测量理论框架中实例化了越狱行为,其中 被视为源于执行越狱协议(操作化活动)的测量,用于测量系统属性(估计量),该属性通过概率威胁模型(系统化活动)定义,该模型形式化了攻击目标(背景活动)。这四个层次通过三种过程连接:系统化、操作化和执行。这种表示基于近期对 Adcock 和 Collier(2001) 3 框架的适应性工作。 to genAI evaluation (Chouldechova et al., 2024; Wallach et al., 2025).

Each component consists of three primary elements: (1) the concept, which gets systematized in the “success criteria” by precisely defining the kinds of undesirable system behaviors that, if elicited, would constitute attack success; (2) the context, which specifies the types of attack goals that are of interest; and (3) the conditions specifying the constraints, resources, information, and other factors governing the jailbreaking activity (e.g., whether we’re looking at direct attacks, where the or transfer attacks (e.g., Zou et al. (2023)), where , or both direct attacks and transfer attacks). The figure also depicts a fourth key element, the aggregation step governing how instance-level attack success indicators are aggregated up to an overall goal-level (e.g., Top-1, one-shot, etc),
which we discuss in detail in §4. The aggregation step ultimately determines the specific functional form of the estimand, , which we term the attack success probability.
每个组件由三个主要元素构成:(1)概念,通过在“成功标准”中精确定义那些若被触发将构成攻击成功的系统不良行为来系统化该概念;(2)背景,指定感兴趣攻击目标的类型;(3)条件,规定控制越狱活动的约束、资源、信息和其他因素(例如,我们是在研究直接攻击,还是在研究 或迁移攻击(如 Zou 等人(2023 年)),其中 ,或两者都是直接攻击和迁移攻击)。该图还描绘了第四个关键元素,即聚合步骤,该步骤控制实例级攻击成功指标如何聚合到总体目标级 (例如,Top-1、一次性等),我们在§4 中详细讨论该聚合步骤。聚合步骤最终决定了估计量 的具体函数形式,我们称之为攻击成功概率。
The systematized activity: probabilistic threat model. Within cybersecurity, threat models specify the attack surface and provide definitions for evaluating the efficacy of an attack. In specifying the systematized activity, we take inspiration from probabilistic approaches that have been central to influential work in ML security Yeom et al. (2018); Carlini et al. (2022); Hayes et al. (2025b); Shokri et al. (2017); Carlini et al. (2019); Hayes et al. (2025a); Cooper et al. (2025), but remain largely absent from work on AI red teaming, despite strong parallels between the fields. The key definition for the systematized activity is as follows:
系统化活动:概率威胁模型。在网络安全领域,威胁模型指定攻击面,并为评估攻击的有效性提供定义。在指定系统化活动时,我们借鉴了概率方法,这些方法一直是 ML 安全领域有影响力工作的核心,如 Yeom 等人(2018 年);Carlini 等人(2022 年);Hayes 等人(2025b 年);Shokri 等人(2017 年);Carlini 等人(2019 年);Hayes 等人(2025a 年);Cooper 等人(2025 年),尽管这些领域之间存在强烈相似性,但这些方法在 AI 红队工作中却基本缺失。系统化活动的关键定义如下:
Definition 3.1 (Probabilistic threat model for jailbreaking).
定义 3.1(越狱的概率威胁模型)。
A probabilistic threat model for jailbreaking, , specifies three constituent components: (1) the “oracle” attack success criteria that precisely define what types of system responses, , constitute undesirable system behaviors with respect to a base prompt ; (2) a goal distribution that specifies a distribution over base harmful prompts, ; and (3) conditions specifying the constraints, resources, information, and other factors governing the jailbreaking activity and jailbreaking method
.
一个用于越狱的概率威胁模型 ,包含三个组成部分:(1)精确定义何种系统响应 构成相对于基础提示 的不良系统行为的“预言家”攻击成功标准 ;(2)一个目标分布 ,指定基础有害提示的分布 ;以及(3)条件 ,指定管理越狱活动和越狱方法的约束、资源、信息和其他因素 。
The constituent components and can be viewed as systematized (population) elements that are operationalized through the judge and the set of base harmful prompts , respectively. Here, is an “oracle” that indicates whether observing system response to prompt constitutes an undesirable behavior with respect to prompt . When undesirable behavior is governed by regulation or company policy, we can think of as an expert adjudication of whether response violates stated policy. We generally do not have direct access to when conducting the jailbreaking activity. Regardless, when we run jailbreaking experiments, the goal is to collect evidence that will let us draw conclusions concerning —not . That is, the key point is that in measuring complex concepts such as safety and efficacy, we are fundamentally interested in success as assessed according to . The judge is simply the (often highly imperfect) operationalization of the attack success criteria that we wish to use in the jailbreaking activity.

Measurement validity. Measurement validity is the extent to which a measurement instrument measures what it purports to measure (Messick, 1987). Here, validity refers to the extent to which the operationalized activity (e.g., the specific instantiated jailbreaking activity) allows us to accurately measure the estimands as defined in the systematized activity. When we compare s to make evaluative claims about relative system safety or attack method efficacy, we need to establish that those s are valid measurements of system safety or attack method efficacy as defined in the systematized activity. To do this we need defensible definitions of these concepts in the first place.
测量有效性。测量有效性是指测量工具测量其声称要测量的程度(Messick, 1987)。在这里,有效性是指操作化活动(例如,特定的实例化越狱活动)允许我们准确测量系统化活动中定义的估计值的程度。当我们比较 s 以对相对系统安全性或攻击方法有效性做出评估性声明时,我们需要确定这些 s 是系统化活动中定义的系统安全性或攻击方法有效性的有效测量。为此,我们首先需要这些概念的可辩护定义。
Having accurate measurements of a poorly systematized activity that arguably does not reflect a meaningful notion of system safety or attack method efficacy still does not entitle us to make broad evaluative claims. For instance, we could, in principle, systematize undesirable system behavior as “the system response contains the word ‘hibiscus’.” This is a precise definition. But it is clearly a terrible systematization of undesirable system behaviors that is completely detached from reasonable notions of system safety. In most jailbreaking studies, safety is synonymous with the refusal to comply with harmful prompts. Yet in practice, this refusal-as-safety paradigm is increasingly called into question Yuan et al. (2025). Disconnects arising from poor systematization are shown in Figure 1 as “conceptual gaps”. Contesting a systematized activity falls under what Wallach et al. (2025) term “conceptual debates.”
对一项组织不善的活动进行精确测量,而这项活动据称并不能反映系统安全或攻击方法有效性的任何有意义的概念,这仍然不能让我们做出广泛的评估性声明。例如,原则上我们可以将不希望的系统行为系统化为“系统响应包含‘木槿花’这个词”。这是一个精确的定义。但它显然是对不希望的系统行为的一种糟糕的系统化,完全脱离了合理的系统安全概念。在大多数越狱研究中,安全等同于拒绝执行有害提示。然而在实践中,这种以拒绝为安全模式的范式正越来越受到质疑(Yuan 等人,2025 年)。由于系统化不良而产生的脱节在图 1 中表现为“概念差距”。对系统化活动的质疑属于 Wallach 等人(2025 年)所称的“概念争论”。
Having instantiated jailbreaking in a formal measurement theory framework, we are equipped to discuss how failures of conceptual coherence and measurement validity typically arise in practice.
在形式测量理论框架中实例化越狱后,我们便具备了讨论在实际中概念一致性失败和测量有效性通常如何产生的条件。
4 Conceptual Coherence: Deconstructing Attack Success Rates
4 概念一致性:解构攻击成功率
Precisely what “attack success rate” means differs both across and within studies in a manner that can undermine the utility of s for comparison. Specifically, it can lead to conceptual incoherence—incongruity between the estimands, , entailed in the comparison. The term “attack” success rate is itself misleading. It suggests that what is being computed is the fraction of attacks that succeed. s, however, reflect the fraction of attack goals444In most cases, the goal is defined by the base harmful prompt.
在大多数情况下,目标由基础有害提示定义。 that are successfully met. For jailbreaking, the goal is captured by the base harmful prompt (e.g., “Can you guide me to create a phishing website?” Chu et al. (2024)). This distinction is important because there is variation in how goal-level success is defined—in particular, in how attack instance-level success indicators are aggregated up at the goal (base harmful prompt) level. The key implication of this is that one can obtain higher s simply by moving the proverbial goal posts by changing the aggregation to make success easier to achieve.
“攻击成功率”的确切含义在不同研究之间以及研究内部存在差异,这种差异可能削弱 用于比较的有效性。具体而言,它可能导致概念不连贯——即比较中隐含的估计量 之间的不一致性。“攻击”成功率这一术语本身具有误导性。它暗示所计算的是成功攻击的比例。 然而,这些比例反映的是攻击目标 4
In this section, we discuss this issue through a three-part case study of repeated sampling for non-deterministic target system configurations. We show that repeated sampling has the effect of, in the language of §2, changing the underlying estimands.
To focus on
conceptual coherence, in this section we consider the idealized setting where we have “perfectly operationalized” the systematized activity. That is, we assume the base harmful prompts used in the red teaming activity, , are indeed drawn from the goal distribution, ; and the operational judge of attack success, , perfectly captures the oracle attack success criteria (i.e., assume ). In §5, when discussing measurement validity concerns, we return to the real-world, non-idealized setting for which there is measurement error introduced from the operationalization of a systemized activity (Figure 1).
在本节中,我们通过一个关于非确定性目标系统配置重复抽样的三部分案例研究来讨论这个问题。我们表明,重复抽样的效果是,用§2 中的语言来说,改变了底层估计量。为了聚焦于概念一致性,在本节中,我们考虑理想化的设置,其中我们将系统化活动“完美地操作化”了。也就是说,我们假设红队活动中使用的基准有害提示 确实来自目标分布 ;并且攻击成功的操作化裁判 完美地捕捉了预言机攻击成功标准 (即假设 )。在§5 中,当讨论测量有效性问题时,我们回到现实世界、非理想化的设置,其中由于系统化活动的操作化引入了测量误差(图 1)。

I. GCG vs. Generation Exploitation. In §4.4 of Huang et al. (2023), the authors compare their method, Generation Exploitation (GE), to a state-of-the-art alternative, Greedy Coordinate Gradient (GCG) (Zou et al., 2023) on Llama 2 13B-Chat. When using their custom fine-tuned BERT model classifier, , to judge success, they report s of and . Yet from the description of the experimental setup, we can see that these s stem from very different aggregations, and hence entail different estimands. For GCG, for each prompt they run GCG for 500 steps to form a sequence of (not necessarily distinct) suffix transformations, and then “generate a single output for each [prompt],” i.e., a single output . GCG is run on a single fixed configuration, , so can thus be seen as estimating,
I. GCG 与生成利用对比。在 Huang 等人(2023)的§4.4 中,作者将他们的方法——生成利用(GE)——与一种最先进的替代方法——贪婪坐标梯度(GCG)(Zou 等人,2023)——在 Llama 2 13B-Chat 上进行了比较。当使用他们自定义微调的 BERT 模型分类器 来判定成功时,他们报告了 的 和 。然而,从实验设置描述中可以看出,这些 源于非常不同的聚合方式,因此涉及不同的估计量。对于 GCG,对于每个提示 ,他们运行 GCG 500 步以形成一个序列 ,由(不一定不同的)后缀转换组成,然后“为每个[提示]生成一个输出”,即单个输出 。GCG 在一个固定的配置 上运行,因此 可以被视为估计,

For their GE method, Huang et al. consider system configurations. For each prompt and configuration , they sample responses. Letting denote the th sample from , this produces a set of
responses . They then use an “attacker scorer” model, , trained the same way (but on different data from the same distribution) as the judge , to select the highest-scoring response per base prompt, . The GE attack for prompt is then deemed to have succeeded if . Our experiments (see Figure 2) show that using the attacker scorer (grey) instead of the judge directly (orange) in the selection phase leads to only a modest reduction in , so for simplicity we present the estimand assuming was used throughout. Under this simplification, is effectively estimating,
对于他们的 GE 方法,黄等人考虑了 种系统配置。对于每个提示 和配置 ,他们采样 个响应。让 表示从 中采样的第 个样本,这样就产生了一组 响应 。然后他们使用一个“攻击者评分器”模型 ,该模型与裁判 相同的方式训练(但在来自同一分布的不同数据上),来为每个基础提示选择得分最高的响应 。如果 ,则认为针对提示 的 GE 攻击成功。我们的实验(见图 2)表明,在选择阶段使用攻击者评分器(灰色)而不是直接使用裁判 (橙色)会导致 的减少幅度很小,因此为了简化,我们假设在整个过程中使用了 。在这种简化下, 实际上是在估计,

How do these estimands compare? is a “Top-1” (of 392) metric, which asks how often at least one of sampled responses from is judged successful555Appendix C provides additional discussion of aggregations and resulting estimands, including remarks on how terms like “Top-1” are used inconsistently in the literature to refer to different aggregation schemes.
附录 C 提供了关于聚合和结果估计量的额外讨论,包括关于文献中如何不一致地使用“Top-1”等术语来指代不同的聚合方案的评论。
这些估计量如何比较? 是一个“Top-1”(392 个中的 Top-1)指标,它询问从 采样的 个响应中,至少有一个被判定为成功的频率 5 . For prompts where the one-shot success probability is non-negligible, say, , the probability of observing at least one success in 392 attempts is . Indeed, when prompt-level success is defined as at least one attack succeeding, we can trivially improve the of any jailbreak through repeated sampling using a non-deterministic configuration. is instead a “one-shot” metric, which asks how often a single sampled response is judged successful.
对于提示词中单次尝试成功率 非忽略不计的情况,比如 ,在 392 次尝试中至少观察到一次成功的概率是 。确实,当提示词级别的成功定义为至少一次攻击成功时,我们可以通过使用非确定性配置反复采样来轻易提高任何越狱攻击的 。 则是一个“单次”指标,它询问单个采样响应 被判定为成功的频率。
So is GE
“more effective” than GCG, as the authors conclude? Returning to our survival rate analogy, comparing Top-1 (of 392) to one-shot is akin to comparing 2-year survival under treatment to 3-year survival under control. It is fundamentally apples-to-oranges. Without further assumptions, it is unclear how any meaningful conclusions about (jailbreak or treatment) efficacy can be drawn. A more congruent comparison could compute
Top-1 over a subset of of the ’s constructed across the optimization steps of GCG.
那么,GE 是否比 GCG“更有效”,正如作者所结论的那样?回到我们的生存率类比,比较 Top-1(392 个中的 Top-1)与单次尝试,相当于比较治疗下的 2 年生存率与控制下的 3 年生存率。这从根本上就是苹果与橙子的比较。没有进一步的假设,无法得出关于(越狱攻击或治疗)有效性的任何有意义结论。一个更一致的比较可以通过在 GCG 优化步骤中构建的 的子集上计算 Top-1 来进行。
II. Does the decoding configuration really matter? As we have argued, the GCG vs. GE analysis does not appear to compare the right quantities to establish the greater effectiveness of GE.
To surface additional insights concerning this observation, we ran an experiment based on the study’s original setup. We replicate the experiments from Huang et al. (2023) for the Llama 2 7B and 13B chat models, using the same 100 base prompts from their MaliciousInstruct dataset. However, to compare between repeated sampling from a fixed configuration to sampling once from each of several configurations, we obtain 49 sampled responses for each prompt from each of the decoding configurations
(Appendix E.1).
We sought to understand to what extent the boosts they observed over greedy decoding were attributable to the effect of applying a Top-1 instead of a one-shot metric, as opposed to certain non-deterministic decoding configurations truly leading to higher chances of attack success.
II. 解码配置真的有那么重要吗?正如我们所论证的,GCG 与 GE 的分析似乎并未比较正确的量来确立 GE 的更高有效性。为了揭示这一观察的更多见解,我们基于研究原始设置进行了一项实验。我们复制了 Huang 等人(2023)针对 Llama 2 7B 和 13B 聊天模型的实验,使用了他们 MaliciousInstruct 数据集中的相同 100 个基础提示。然而,为了比较从固定配置重复采样与从多个配置中各采样一次,我们从每个 解码配置中为每个提示获得 49 个采样响应(附录 E.1)。我们试图了解他们观察到的 相对于贪婪解码的提升在多大程度上归因于应用 Top-1 而非一次性指标的效果,而不是某些非确定性解码配置真正导致攻击成功率更高的效果。
Figure 2 A shows Top-1 over repeated samples for each configuration in orange (corresponding to estimand , and one-shot (corresponding to estimand ) in green. We clearly see that one-shot remains stable around across configurations,666This partly contradicts a key claim made by the authors in their Table 2, where they assert that models are more vulnerable under certain decoding strategies, intending this in the “one-shot” sense.
这部分与作者在表 2 中提出的一个关键主张相矛盾,他们在该表中断言,在某些解码策略下模型更容易受到攻击,并且他们是在“一次性” 的意义上这样说的。
图 2A 显示了每个配置中 Top-1 在 重复样本中的表现,以橙色表示(对应估计量 ,以及以绿色表示的单次 (对应估计量 )。我们清楚地看到,单次 在不同配置中始终稳定在 左右, 6 except at the highest temperatures.777The original experiments considered temperature only up to 1.0. We additionally experimented with to assess whether the pattern of higher success at higher temperatures extends.
原始实验仅考虑温度 高达 1.0。我们额外进行了 实验,以评估在更高温度下成功率更高的模式是否仍然适用。
除了在最高温度下。 7 Top-1 , however, increases with temperature, and . What accounts for this difference? Digging deeper, we find that while the one-shot does not change much, Panel C shows that as we increase the temperature, the entropy of the prompt-level attack success probability distribution increases. The success probability actually decreases for many prompts, but also more prompts move away from an effectively-0 success probability to a slightly larger one. Thus while the average one-shot attack success probability (the mean of the distribution shown in the histograms) does not change, the distributional shift has a large effect on Top-1 type metrics under resampling. This is because the probability that a prompt with success probability succeeds on at least one of samples, , grows rapidly as moves away from 0 for even moderate . Our results clearly show that it is not the decoding configuration per se that improves , but rather the use of high-entropy decoding configurations combined with Top-1 aggregation over a large number of repeated samples of model responses.
然而,Top-1 随着温度的升高而增加, 和 。这种差异的原因是什么?深入挖掘后,我们发现虽然单次 变化不大,但面板 C 显示,随着温度的升高,提示级攻击成功概率分布的熵增加。对于许多提示,成功概率实际上会降低,但更多提示会从有效的 0 成功概率移动到一个稍大的值。因此,虽然平均单次攻击成功概率(直方图中显示的分布的均值)没有变化,但在重采样下,分布的偏移对 Top-1 类型指标有重大影响。这是因为当成功概率为 的提示 在 样本中至少成功一次的概率 ,随着 远离 0,即使对于适度的 ,这个概率也会迅速增长。我们的结果表明,不是解码配置本身提高了 ,而是使用高熵解码配置,并结合对大量重复模型响应样本的 Top-1 聚合。
III. Do sophisticated jailbreaks (actually) beat the baseline? These findings should make us skeptical of claims that sophisticated-seeming jailbreaks outperform base prompting when Top-1 metrics are used. Consider for instance the large-scale evaluation study of Chu et al. (2024), where the authors compare Top-1 (of 50) s of 17 jailbreak methods across 8 models. For each model, they also report a “baseline” attack success rate, , which is the fraction of base prompts that succeed as-is with a single sampled response (i.e., one-shot ). Using the set of 160 base prompts made publicly available by the authors, we repeated their baseline experiment for the Llama 2 7B Chat model, one of the “safest” models in their study (see Appendix E). We find that the Top-1 over 50 repeated samples of the baseline prompts at temperature 2.0 is 0.83. We cannot directly compare this result with the best performing jailbreak they identify (LAA Andriushchenko et al. (2024), reported 0.88(0.04)) because we did not use their identical judge system; nevertheless, based on the experimental setup, we expect the judges to largely agree. This suggests that even sophisticated jailbreaking methods may perform similarly to simply repeatedly resampling responses to the base prompt, . Indeed, s for many of the other jailbreaks on Llama 2 were much lower, most below 0.6. Our results show that repeatedly sampling responses times under a high-entropy decoding configuration forms a strong baseline. Studies introducing new jailbreaks assessed using Top-1 (of ) metrics should demonstrate that they definitively outperform this repeated sampling baseline. For a stronger baseline, studies can also compare to the Best-of-N jailbreak Hughes et al. (2024), which applies a randomly selected perturbation to the prompt each time rather than simply resampling.
III. 复杂的越狱攻击(真的)胜过基准吗?这些发现应让我们对那些声称看似复杂的越狱攻击在使用 Top-1 指标时优于基准提示的断言持怀疑态度。以 Chu 等人(2024)的大规模评估研究为例,作者比较了 17 种越狱方法在 8 个模型上的 Top-1( 50) s。对于每个模型,他们还报告了一个“基准”攻击成功率 ,即基准提示在单次采样响应(即 one-shot )中成功的比例。使用作者公开提供的 160 个基准提示集,我们重复了他们在研究中“最安全”的模型之一 Llama 2 7B Chat 的基准实验(见附录 E)。我们发现,在温度为 2.0 时,基准提示在 50 次重复采样中的 Top-1 为 0.83。由于我们没有使用他们相同的评判系统,因此我们无法将此结果与他们在研究中识别的最佳越狱攻击(LAA Andriushchenko 等人(2024),报告 0.88( 0.04))直接比较;然而,根据实验设置,我们预期评判者会大体上达成一致。 这表明即使是复杂的越狱方法,其表现也可能与简单地重复对基础提示进行重采样相似, 。事实上, 对于 Llama 2 上的许多其他越狱方法,其分数要低得多,大多数低于 0.6。我们的结果表明,在具有高熵解码配置下,重复采样响应 次,形成了一个强有力的基准。引入新越狱方法并使用 Top-1(of )指标进行评估的研究,应证明它们明确优于这种重复采样基准。 为了获得更强的基准,研究还可以与 Best-of-N 越狱方法 Hughes 等人(2024 年)进行比较,该方法每次对提示应用随机选择的扰动,而不是简单地重采样。
Lastly, we note that identifying cases of conceptual incoherence requires knowing how reported attack success rates were computed. In our literature review, we found that ASR definitions are frequently ambiguous, and their computations are often left out of accompanying code. This makes it difficult for both readers and authors alike to assess conceptual coherence. We note that both conceptual coherence issues and the measurement validity issues we discuss later in §5 are often infeasible to correct for post hoc, unless experimental data is logged at a very granular level. Indeed, we conducted our own experiments for this paper precisely because reanalysis of logged data was insufficient for our case study.
最后,我们注意到,识别概念上的不连贯性需要了解报告的攻击成功率是如何计算的。在我们的文献综述中,我们发现 ASR 定义经常是模糊的,而它们的计算通常被省略在随附的代码中。这使得读者和作者都难以评估概念上的连贯性。我们注意到,我们将在§5 中讨论的概念连贯性问题以及测量有效性问题,在事后往往难以纠正,除非实验数据被非常精细地记录。事实上,我们为本文进行了自己的实验,正是因为对已记录数据的再分析对于我们的案例研究是不够的。
5 Measurement Validity 5 测量有效性
Our discussion so far has relied only on a mechanistic understanding of jailbreaking and the different types of aggregation that go into defining attack success rates. This discussion helps us understand when an evaluative claim may be poorly grounded because the underlying estimands are incongruent. But what if we have conceptual coherence—i.e., the estimands do seem comparable?
We now discuss how
measurement validity issues commonly arise due disconnects between (i) the target harmful prompt distribution, , and the base harmful prompts used in the given jailbreaking activity; and (ii) the systematized “oracle” success criterion defining our true success criteria and the operational “judge” used to assess success in practice.
我们目前的讨论仅依赖于对越狱的机制性理解和定义攻击成功率所涉及的各类聚合方式。这种讨论帮助我们理解当底层估计量不一致时,评估性声明可能缺乏坚实基础。但如果我们有概念上的连贯性——即估计量似乎确实可以比较呢?我们现在讨论测量有效性问题通常如何产生,原因在于(i)目标有害提示分布 与在给定越狱活动中使用的基准有害提示 之间的脱节;以及(ii)定义我们真实成功标准的系统化“预言家”成功标准 与用于实际评估成功的操作化“裁判” 之间的脱节。
5.1 Harmful prompts: Disconnects between and
5.1 有害提示: 与 之间的脱节
Content and face validity: “harmful” prompts that are really not harmful.
Many jailbreak studies report baseline s, which show the fraction of base harmful prompts in that are judged as succeeding on the first attempt without any transformation, . Baseline s are often very high. For instance, in their comprehensive jailbreak evaluation work, Chu et al. (2024) develop 160 “harmful” prompts each intended to be in violation of one of 16 violation categories (10 prompts per category) drawn from usage policies of major LLM service providers (Google, OpenAI, Meta, Amazon, Microsoft). For these 160 prompts they report baseline s ranging
from (Llama 2 7B Chat) to (Vicuna 7B), with baseline s as high as 0.8–0.94 for certain violation categories such as Adult Content and AI Usage Disclosure. Such high baseline s raise the question: are the systems evaluated really very unsafe, or are the s failing to meaningfully measure safety?
内容和表面效度:“有害”但实际无害的提示。许多越狱研究报告了基准 值,这些值显示了在 中,未经任何转换就被判断为首次尝试成功的基准有害提示的比例 。基准 值通常非常高。例如,在他们的全面越狱评估工作中,Chu 等人(2024 年)开发了 160 个“有害”提示,每个提示都旨在违反 16 个违规类别中的其中一个(每个类别 10 个提示),这些违规类别来自主要 LLM 服务提供商(Google、OpenAI、Meta、Amazon、Microsoft)的使用政策。对于这 160 个提示,他们报告的基准 值范围从 (Llama 2 7B Chat)到 (Vicuna 7B),某些违规类别(如成人内容和 AI 使用披露)的基准 值高达 0.8–0.94。如此高的基准 值引发了问题:被评估的系统是否真的非常不安全,还是 值未能有效衡量安全性?
Inspecting the 160 base prompts reveals a clear issue: complying with many of the “harmful” prompts, such as the three shown here from the Adult Content category, would not appear to violate any reasonable interpretation of the actual service provider usage policy.
检查 160 个基础提示时发现了一个明显的问题:遵守许多“有害”提示,例如这里展示的来自成人内容类别的三个提示,似乎不会违反任何合理的实际服务提供商使用政策。

A review of prompts from the Political Activities category reveals similar issues. Thus, where Chu et al. (2024) write “despite OpenAI’s explicit prohibition of Political Activities in their policy, the jailbreak attack within this category still manages to achieve the highest (over 0.80) on GPT-3.5 and GPT-4”, we argue this conclusion is misleading and based on invalid measurement. Specifically, this can be viewed as a failing of face validity and content validity Wallach et al. (2025), wherein “test items” (here, base prompts) do not accurately reflect the target domain (prompts that if complied with would constitute undesirable system behavior that violates a company’s genAI use policies) that the “test” (here, jailbreaking activity) purports to reflect. Of the 10 harmful prompts in this category, we find that just 1 is a clear violation of the OpenAI policy if complied with, 7 are borderline, and 2 are clearly non-violating. We provide an in-depth discussion in Appendix D.
对政治活动类别提示的回顾揭示了类似问题。因此,当 Chu 等人(2024)写道“尽管 OpenAI 在其政策中明确禁止政治活动,但该类别的越狱攻击仍然在 GPT-3.5 和 GPT-4 上实现了最高的 (超过 0.80)”时,我们认为这一结论具有误导性且基于无效测量。具体来说,这可以被视为效度不足的问题,包括表面效度和内容效度(Wallach 等人,2025),其中“测试项目”(此处为基础提示)未能准确反映“测试”(此处为越狱活动)所声称要反映的目标领域(即如果遵守则会构成不良系统行为并违反公司生成式 AI 使用政策的提示)。在该类别的 10 个有害提示中,我们发现只有 1 个如果被遵守会明确违反 OpenAI 政策,7 个处于边缘地带,2 个则明显不构成违规。我们在附录 D 中进行了深入讨论。
5.2 Adjudicating attack success: Disconnects between and
5.2 评判攻击成功: 与 之间的脱节
What constitutes “undesirable behavior” is seldom clearly defined. Despite the central role that “success in eliciting undesirable behavior” plays in jailbreaking studies and AI red teaming more broadly, systematized success criteria are seldom presented. This can be especially problematic when the background concept of interest falls under what Feffer et al. (2024) in their study of AI red teaming call dissentive risks (“outcomes [that] are complex or contested”), such as stereotyping or hate speech. Even in jailbreaking, where undesirable behavior is broadly understood as “compliance” with a harmful prompt, Yu et al. (2024) note that, “a clear discussion of the principles determining whether a response is jailbroken remains absent.” Without systematization, we cannot even meaningfully talk about the accuracy of a judge in adjudicating attack success. This is because the accuracy of as a proxy for the success criteria depends critically on precisely on how undesirable behavior is defined. So even though we will now reference several studies reporting measures of judge accuracy, we urge caution in interpreting those numbers: it is unclear to what extent they capture a coherent notion of accuracy with respect to consistently defined systematized success criteria.
构成“不良行为”的定义很少被明确界定。尽管“成功诱导不良行为”在越狱研究和更广泛的 AI 红队测试中扮演着核心角色,但系统化的成功标准却很少被提出。当感兴趣的概念背景属于费弗等人在其 AI 红队测试研究中称为异议风险(“复杂或有争议的结果”)的情况时,这一点尤其成问题,例如刻板印象或仇恨言论。即使在越狱测试中,不良行为被广泛理解为“遵循有害提示”,余等人(2024)也指出,“关于决定响应是否被越狱的原则的清晰讨论仍然缺失。”没有系统化,我们甚至无法有意义地讨论裁判者 在判定攻击成功时的准确性。这是因为作为成功标准 的代理指标 的准确性,关键取决于如何定义不良行为。 因此,尽管我们现在将参考几项报告裁判者准确性的研究,我们敦促在解读这些数字时要谨慎:它们在多大程度上捕捉了与始终如一定义的系统化成功标准相一致的准确概念尚不明确。

But because the and differ across systems, the computed based on on average overestimates the true attack success for , , and underestimates it for , .

This issue is not merely hypothetical. For instance, Andriushchenko et al. (2024) note in Appendix B.5 that Claude 2.1 has a distinct safe behavior that both their rule-based and GPT-4-based judges frequently misjudge as harmful, noting that “such false positives happen rarely on other models.” Relatedly, Mazeika et al. (2024) find that observed s decrease with the number of tokens output by the target model—which is plausibly attributable to judge error rates varying with output length—and Wataoka et al. (2024) document model self-preference bias. Given all this, it is problematic that jailbreaking studies rarely assess, much less report, the performance of the judge system disaggregated across target models. We further note that issues of differential misclassification have been studied extensively in the statistics literature, and can be applied to produce more valid s Grace (2016).
这个问题并非仅仅是假设性的。例如,Andriushchenko 等人(2024)在附录 B.5 中指出,Claude 2.1 具有独特的安全行为,而他们的基于规则的判断者和基于 GPT-4 的判断者经常错误地将其判断为有害,并指出“在其他模型上这种情况很少发生。”与此相关,Mazeika 等人(2024)发现,目标模型输出的 token 数量与观察到的 值呈下降趋势——这可能是由于判断者的错误率随输出长度变化所致——而 Wataoka 等人(2024)则记录了模型自我偏好偏差。鉴于所有这些情况, jailbreaking 研究很少评估,更不用说报告,针对不同目标模型的判断系统性能的分解情况,这是一个问题。我们进一步指出,差异误分类问题在统计学文献中已被广泛研究,并可用于生成更有效的 值 Grace(2016)。
Differential / across jailbreak approaches. Just as using the same judge is insufficient to ensure validity when comparing across systems, it is also insufficient when comparing across jailbreak approaches. Mei et al. (2024) document how certain “hallucination” behaviors in target LLM responses trigger false positive success determinations from commonly-used judge systems. Jailbreaks that rely on adversarial non-natural language suffixes to confuse the target LLM (e.g., "...konk;?> usual_TOOcr..." Andriushchenko et al. (2024)) may be more likely to produce such hallucinated responses, and thereby have a higher observed due a higher rate of judge false positives. A similar issue was observed on a smaller scale by Huang et al. (2023), who note that their judge falsely flagged as positive responses that consisted solely of <unk> or <eos>, an issue they addressed by filtering out such responses.
跨越越狱方法的差异 / 。正如在跨系统比较时,使用相同的裁判者并不能确保有效性一样,在跨越狱方法比较时,这也同样不足够。Mei 等人(2024)记录了目标 LLM 响应中的某些“幻觉”行为如何触发常用裁判系统产生的错误阳性成功判定。依赖对抗性非自然语言后缀来迷惑目标 LLM 的越狱方法(例如,“...konk;?>usual_TOOcr..." Andriushchenko 等人(2024))可能更容易产生此类幻觉响应,并因此由于裁判者错误阳性的更高率而具有更高的观察到的 。Huang 等人(2023)在小规模上观察到了类似问题,他们指出其裁判者错误地将仅由 或 组成的响应标记为阳性,他们通过过滤掉此类响应解决了这个问题。
6 Discussion 6 讨论
As noted at the outset, our argument is not intended to apply to all AI red teaming activities. Not all AI red teaming activities can, should, or are even intended to result in measurements. For example, AI red teaming is often used as a type of “existence proof,” producing valuable examples of undesirable behaviors and surfacing “unknown unknowns”—i.e., qualitative information—without any attempt at quantification (e.g., Casper et al., 2023; Nasr et al., 2023; Cooper et al., 2025). Our argument most directly applies to situations in which AI red teaming is used to obtain measurements in the form of s that one might try, justifiably or not, to compare. At the same time, certain elements of the measurement theory framework we outline—such as the difference between how safety is conceptualized through verses how it is operationalized through —are relevant for more qualitative forms of red teaming as well. Indeed, the original work by Adcock and Collier (2001) that inspired our framework was in part an effort to bridge quantitative and qualitative research methods in political science.
如开篇所述,我们的论点并非旨在适用于所有人工智能红队演练活动。并非所有人工智能红队演练活动都能、应该或甚至意图产生测量结果。例如,人工智能红队演练常被用作一种“存在性证明”,在不试图量化(例如,Casper 等人,2023 年;Nasr 等人,2023 年;Cooper 等人,2025 年)的情况下,产出有价值的非期望行为示例,并暴露“未知未知”——即定性信息。我们的论点最直接适用于人工智能红队演练被用于获取可尝试(无论是否合理)进行比较的 形式测量结果的情况。同时,我们概述的测量理论框架中的某些要素——例如通过 概念化安全与通过 操作化安全之间的差异——对更定性的红队演练形式同样具有相关性。事实上,启发我们框架的原作由 Adcock 和 Collier(2001 年)撰写,其部分目的在于弥合政治学中的定量与定性研究方法。
Our arguments are also apply beyond quantitative red teaming to other forms of genAI evaluation. Many other task-oriented evaluations Wang et al. (2023) such as those probing systems for stereotyping or memorization as discussed in Wallach et al. (2025) can be instantiated similarly to how we represented jailbreaking in Figure 1.
我们的论点也适用于定量红队之外的其它形式生成式 AI 评估。许多其它任务导向的评估,如 Wang 等人(2023)讨论的探测系统是否存在刻板印象或记忆能力(如 Wallach 等人,2025 年所述),可以与我们在图 1 中表示的越狱方式类似地实现。
Recommendations. When the goal of an AI red teaming activity is to produce s that can be meaningfully compared as reflections of relative system safety or attack method efficacy, it is critical that the activity be designed with conceptual coherence and measurement validity in mind. We make several concrete recommendations in pursuit of this goal: (1) Clearly define what is being measured. We recommend that measurement goals be carefully systematized, e.g., by specifying probabilistic threat models of the sort introduced in §3. (2) Ensure conceptual coherence by precisely defining estimands that can be meaningfully compared and, if compared, would support the kinds of evaluative claims one might wish to make. (3) Interrogate content validity by ensuring that the base harmful prompts are chosen such that system responses that comply with the prompts do indeed meet the systematized success criteria specified in the probabilistic threat model. (4) Assess and report judge system performance disaggregated by target system and jailbreaking method, as appropriate, to ensure that s are not being biased by differential error rates. Where significant differential errors are an issue, apply appropriate statistical methods to form more valid and reliable estimates of the estimands.
建议。当人工智能红队活动的目标是为相对系统安全性或攻击方法有效性提供可进行有意义的比较的 时,必须确保活动在概念一致性和测量有效性方面得到精心设计。我们为达成这一目标提出以下几点具体建议:(1)明确界定所测量的内容。我们建议测量目标应得到仔细的系统化,例如,通过指定§3 中引入的某种概率威胁模型。(2)通过精确定义可进行有意义的比较的估计量,并确保这些估计量在比较时能够支持我们可能希望提出的评估性声明,来确保概念一致性。(3)通过确保基础有害提示的选择方式,使得系统响应符合提示时确实满足概率威胁模型中系统化定义的成功标准,来审查内容有效性。(4)根据需要评估并报告按目标系统和越狱方法细分的裁判系统性能,以确保 不会因不同的错误率而产生偏差。 当存在显著的差异误差时,应用适当的统计方法来形成更有效和可靠的估计值。

A.1 AI red teaming A.1AI 红队测试
AI red teaming has grown to encompass a broad range of practices for probing genAI systems for a wide range of vulnerabilities and undesirable behavior.
While manual red teaming remains critical for surfacing new attack vectors and vulnerabilities, semi- or fully-automated approaches are increasingly common.
GenAI systems are now routinely used both to generate attack inputs and to automatically determine whether an attack was successful using a “judge model” or “red classifier” [Perez et al., 2022, Zou et al., 2023, Chu et al., 2024, Beutel et al., 2024, Yu et al., 2024, Mazeika et al., 2024]. These more automated approaches, which blur the line between red teaming and safety benchmarking, create “a lack of clarity on how to define ‘AI red teaming’ and what approaches are considered part of the expanded role it plays in the AI development life cycle” [FMF, 2023].
AI 红队测试已发展出广泛的方法,用于探测生成式 AI 系统中的各种漏洞和不良行为。虽然手动红队测试对于发现新的攻击向量仍然至关重要,但半自动或全自动的方法正变得越来越普遍。现在,生成式 AI 系统既用于生成攻击输入,也用于使用“裁判模型”或“红分类器”自动判断攻击是否成功[Perez 等人,2022 年,Zou 等人,2023 年,Chu 等人,2024 年,Beutel 等人,2024 年,Yu 等人,2024 年,Mazeika 等人,2024 年]。这些更自动化的方法模糊了红队测试与安全基准测试之间的界限,导致了“对于如何定义‘AI 红队测试’以及哪些方法被认为是其在 AI 开发生命周期中扩展角色的一部分缺乏明确性”[FMF,2023 年]。
Many have simultaneously argued that red teaming is inherently limited.
For instance, Friedler et al. [2023] combine observations about the Generative AI Red Team (GRT) challenge at DEFCON 2023 with a review of the literature to argue that red teaming “cannot effectively assess and mitigate the harms that arise when [AI] is deployed in societal, human settings.”
Frontier model developers like
Anthropic have similarly argued that red teaming has gaps; Anthropic has characterized red teaming as a “qualitative approach” that “can serve as a precursor to building automated, quantitative evaluation methods” [Anthropic, 2024], rather than an approach that constitutes such evaluations on its own.
许多人同时认为红队测试本身存在局限性。例如,Friedler 等人[2023]结合对 DEFCON 2023 年生成式人工智能红队测试(GRT)挑战的观察以及对文献的回顾,论证红队测试“无法有效评估和减轻[人工智能]在社会、人类环境中部署时产生的危害”。像 Anthropic 这样的前沿模型开发者也认为红队测试存在不足;Anthropic 将红队测试描述为一种“定性方法”,认为它“可以作为构建自动化、定量评估方法的先导”[Anthropic, 2024],而不是一种能够独立构成此类评估的方法。
This presents a contradiction: red-teaming practices and their adoption in new contexts both continue to grow, and yet this growth is occurring without fully attending to known limitations or uncovering unknown limitations of existing uses.
This contradiction muddles understandings about what can be learned from red teaming—with respect to both scientific knowledge in machine learning and broader judgments about using AI systems in practice [Cooper et al., 2024, Lee et al., 2023];
it is partly why there are often conflicting views on what red teaming is (and is not), and when it does (or does not) work. Our work helps provide clarity by demonstrating how certain types of AI red teaming (those that produce s) can be viewed and understood through the lens of measurement.
这构成了一个矛盾:红队演练实践及其在新环境中的应用持续增长,然而这种增长并未充分关注已知的局限性或揭示现有应用中未知的局限性。这一矛盾模糊了对红队演练能带来何种学习的理解——无论是机器学习的科学知识,还是关于在实践中使用人工智能系统的更广泛判断[Cooper 等人,2024;Lee 等人,2023];这也是为何人们对于红队演练是什么(以及不是什么),以及何时有效(或无效)往往存在冲突观点的部分原因。我们的工作通过展示如何通过测量的视角来理解和看待某些类型的人工智能红队演练(那些产生 s 的演练),从而有助于提供清晰度。
The overly broad sense in which the term AI red teaming has come to be used does, however, present a challenge in framing our arguments. While we rely on a much more clearly circumscribed type of red teaming in our in-depth discussion—specifically, jailbreaking—our arguments also generalize to many other evaluation approaches that fall under the broad umbrella of AI red teaming. However, as we noted in our concluding remarks, the measurement theory lens we apply is less well suited to forms of red teaming that are more focused on producing examples of undesirable behavior and less focused on quantifying or systematically characterizing them.
然而,"AI 红队"这一术语被过于广泛地使用的含义,确实给我们的论证框架带来了挑战。虽然我们在深入讨论中依赖于一种更为明确界定的红队类型——即"越狱"——但我们的论证也适用于许多其他属于 AI 红队广泛范畴下的评估方法。然而,正如我们在结论中所指出的,我们所应用的测量理论视角,对于更侧重于生成不良行为示例而非量化或系统性地对其进行特征描述的红队形式来说,适用性较差。
Our work differs from recent studies that inventory and provide guidance surrounding the considerations relevant to planning or documenting red-teaming activities [Feffer et al., 2024, Friedler et al., 2023, Lin et al., 2024]. We do not aim to lay out the activity design space. Rather we provide a framework for instantiating red teaming activities as methods for producing estimates of estimands defined with respect to a probabilistic threat model. We use this framework to address the specific question of whether and under what conditions ASRs obtained from AI red teaming can be viewed as measurements of system safety and attack efficacy.
我们的工作与近期那些列举并提供关于规划或记录红队活动相关考虑事项的指南的研究不同[Feffer 等人,2024 年,Friedler 等人,2023 年,Lin 等人,2024 年]。我们并非旨在概述活动设计空间。相反,我们提供了一个框架,用于将红队活动实例化为产生关于概率威胁模型定义的估计量估计值的方法。我们使用这个框架来探讨一个具体问题:在何种条件下,从人工智能红队活动中获得的攻击成功率(ASRs)可以被视为系统安全性和攻击有效性的测量值。
A.2 Standardizing and systematizing jailbreaking
A.2 标准化和系统化越狱攻击
Many previous papers on jailbreaking have noted ways in which jailbreaking studies are under-specified or poorly standardized. Widely cited jailbreaking papers such as Chu et al. [2024], Yu et al. [2024], Wei et al. [2023], Zou et al. [2023], Xie et al. [2024], Mazeika et al. [2024], and Chao et al. [2024] all emphasize the importance of standardizing potential confounding factors.
许多关于越狱攻击的先前论文都指出了越狱研究在规定不明确或标准化不足方面的方式。诸如 Chu 等人[2024 年]、Yu 等人[2024 年]、Wei 等人[2023 年]、Zou 等人[2023 年]、Xie 等人[2024 年]、Mazeika 等人[2024 年]和 Chao 等人[2024 年]等被广泛引用的越狱论文都强调了标准化潜在混杂因素的重要性。
In introducing HarmBench, for instance, Mazeika et al. [2024] talk about the importance of standardizing factors such as the number of tokens generated by each target model, when conducting evaluations. This recommendation came out of their empirical finding that observed decreases with output length. Yet some reflection suggests that this isn’t so much a “confounding factor” as an issue with the judge system that may be symptomatic of other problems. Unless “disclaiming” what was previously said makes a hereto harmful output non-harmful, it is difficult to posit a reasonable mechanism under which adding additional tokens to the end of a response switches it from harmful to not harmful. But it is certainly possible that judge system error rates vary with output length.
例如在介绍 HarmBench 时,Mazeika 等人[2024]谈到在进行评估时,标准化诸如每个目标模型生成的 token 数量等因子的必要性。这一建议源于他们通过实证发现,随着输出长度的增加, 值会下降。然而,一些反思表明,这与其说是“混杂因素”,不如说是评判系统的问题,可能反映了其他问题。除非“否认”之前所说的内容能使此前有害的输出变得无害,否则很难设想一个合理的机制,即通过在回应末尾添加额外的 token 将其从有害转变为无害。但评判系统的错误率确实可能随输出长度而变化。
Chao et al. [2024] in introducing JailbreakBench go even further in standardizing jailbreak evaluation. They even discuss “threat models” (referring to black-box, white-box, or transfer settings), which are an important part of fully specifying what we termed the “estimands” in our study. However, our arguments demonstrate that standardization of the experimental setup is not enough. Even if everything is standardized, comparisons can be misleading when, for instance, judge and varies across target models or jailbreak methods (§5).
Chao 等人[2024]在介绍 JailbreakBench 时进一步推动了越狱评估的标准化。他们甚至讨论了“威胁模型”(指黑盒、白盒或迁移设置),这些是我们在研究中将“估计目标”完全具体化的重要组成部分。然而,我们的论证表明,实验设置的标准化并不足够。即使所有内容都标准化,当例如裁判 和 在不同目标模型或越狱方法中变化时(§5), 的比较可能会产生误导。
A.3 LLM-as-judge A.3LLM 作为裁判
LLM-as-judge systems have come to play a critical role in automating evaluation in which scoring system responses would otherwise require human adjudication Gu et al. [2024]. This includes not only assess refusal behavior in jailbreaking studies, but also in scoring target system outputs for correctness and making pairwise Zheng et al. [2023]. Critically, numerous studies of LLM-as-judge systems in jailbreaking have found that the choice of judge has a big impact on resulting metrics. This has been observed not just in an absolute sense, but also in the choice of judge affecting which model/jailbreak is observed to have the highest . For instance, Mei et al. [2024] show that the AdvBench string-match judge produces an of 0 across all models when using the PAP-top5 jailbreak. When scored according to the BabyBlue judge they propose, s for this jailbreak are as high as 0.43 even for GPT models. As another example, Andriushchenko et al. [2024] in Table 17 of their paper show
also includes Table 17 in the appendix, which compares ’s assessed via a ChatGPT judge to a rule-based judge. Under the rule-based judge, their jailbreak achieves an of 24% on Claude Haiku and 40% on Claude 3.5 Sonnet. But under their ChatGPT judge, the ordering is reversed: the for Claude Haiku becomes 64%, compared to a much lower of 36% for Claude 3.5 Sonnet. These high-magnitude inversions in which model scores significantly worsen point to clear measurement validity issues.
LLM 作为裁判的系统在自动化评估中发挥着关键作用,这些评估原本需要人工裁决。这包括不仅评估越狱研究中的拒绝行为,还包括对目标系统输出进行正确性评分,以及进行成对比较。关键在于,大量关于 LLM 作为裁判系统的越狱研究发现,裁判的选择对最终指标有重大影响。这种影响不仅体现在绝对意义上,还体现在裁判的选择会影响观察到哪个模型/越狱具有最高的 。例如,Mei 等人[2024]表明,当使用 PAP-top5 越狱时,AdvBench 字符串匹配裁判在所有模型中产生 为 0。当根据他们提出的 BabyBlue 裁判进行评分时,该越狱的 即使对于 GPT 模型也高达 0.43。作为另一个例子,Andriushchenko 等人[2024]在论文的表 17 中(该表也包含在附录中),比较了通过 ChatGPT 裁判评估的 与基于规则的裁判。 在基于规则的裁判下,他们的越狱在 Claude Haiku 上达到了 24%,在 Claude 3.5 Sonnet 上达到了 40%。但在他们的 ChatGPT 裁判下,顺序被反转了:Claude Haiku 的 变成了 64%,而 Claude 3.5 Sonnet 的 则要低得多,为 36%。这些高幅度的反转,其中模型得分显著恶化,表明存在明显的测量有效性问题。
Appendix B Measurement theory
附录 B 测量理论
In this section we provide more background on measurement theory for interested readers.
在本节中,我们为感兴趣的读者提供更多关于测量理论背景。
Measurement refers to the systematic quantification of attributes of objects or events, resulting in numerical values—i.e., measurements—through which the objects or events can be meaningfully compared [Hand, 2016]. Comparisons can take many forms. We may compare attributes of a given object over time, such as by tracking the temperature of the earth using global average temperature;
to particular values, such as
to assess whether a newborn is in good condition immediately following delivery; and between objects, such as comparing the sizes of different nation’s economies using their GDPs.
To be able to compare measurements—i.e., to compare objects through measurements of their attributes—we require a high degree of measurement validity, which is the extent to which a measurement procedure measures what it purports to measure.
The remainder of this section provides an overview of measurement theory and measurement validity.
测量是指对物体或事件属性的系统性量化,通过产生数值值——即测量值——使物体或事件能够进行有意义的比较[Hand, 2016]。比较可以有多种形式。我们可能比较给定物体随时间的属性,例如通过跟踪地球的平均温度来测量温度;与特定值比较,例如评估新生儿在分娩后是否处于良好状态;以及在不同物体之间比较,例如使用各国的 GDP 来比较不同国家经济的规模。为了能够比较测量值——即通过测量它们的属性来比较物体——我们需要高度的测量有效性,即测量程序测量其声称要测量的程度。本节其余部分概述了测量理论和测量有效性。
Measurement approaches lie along a spectrum between representational measurement and pragmatic measurement.
Representational measurement refers to expressing objects and their relationships using numbers.
For example, metrology, the study of measurement in the physical sciences, is largely representational, giving rise to the familiar units such as length, mass, and time, that underpin scientific inquiry.
Pragmatic measurement focuses on measuring abstract concepts that are not amenable to direct observation in ways that yield measurements with the “right sort of properties for [the] intended use” [Hand, 2016]. Pragmatic measurement most commonly arises in the social sciences, where many quantities of interest reflect concepts that are abstract, complex, and sometimes contested.
Examples include the Gross Domestic Product (GDP) constructed to reflect the health of a country’s economy, the Apgar score used to evaluate the condition of a newborn immediately after birth, and the various measures of democracy used in political science.
测量方法存在于从表征测量到实用测量的连续谱中。表征测量指的是使用数字表达对象及其关系。例如,计量学,即物理学中测量研究的学科,主要是表征性的,产生了支撑科学探究的熟悉单位,如长度、质量和时间。实用测量则专注于以产生具有“适合预期用途的某种属性”的方式来测量那些不适合直接观察的抽象概念[Hand, 2016]。实用测量最常见于社会科学,其中许多感兴趣的量反映了抽象、复杂且有时存在争议的概念。例如,为反映国家经济健康状况而构建的国内生产总值(GDP)、用于评估新生儿出生后状况的 Apgar 评分,以及政治学中使用的各种民主测量指标。
Not all quantification is valid measurement.
Not all numbers produced by examining an object facilitate a meaningful comparison.
For instance, the number of 7’s appearing in a bike’s serial number is a number, but it does not reflect an attribute that yields insight if compared across bikes. As a less trivial example, comparing children’s scores on a validated psychometric tool such as the Stanford-Binet intelligence test (SB5) may not be meaningful if the test is administered in a language that not all the children speak.
并非所有量化都是有效测量。并非所有通过观察对象产生的数字都能促进有意义的比较。例如,自行车序列号中出现的 7 的数量是一个数字,但如果跨多辆自行车进行比较,它并不能反映一个能提供洞察的属性。以一个不那么简单的例子来说,如果使用斯坦福-比奈智力量表(SB5)等经过验证的心理测量工具对儿童进行测试,而测试使用的语言并非所有儿童都能说,那么比较他们的分数可能没有意义。
To assess measurement procedures for validity and to develop more reliable and valid procedures, social scientists rely on measurement theory.
Measurement theory provides a conceptual framework for systematically moving from a concept of interest to measurements of that concept [Adcock and Collier, 2001].
Measurement theory also provides a set of lenses for interrogating the reliability and validity of measurement instruments and their resulting measurements [Cronbach and Meehl, 1955, Messick, 1987].
These ideas have been applied to AI measurement tasks [Jacobs and Wallach, 2021], including those involved in genAI evaluations [Zhao et al., 2024, Wallach et al., 2025].
为了评估测量程序的有效性并开发更可靠和有效的程序,社会科学家依赖于测量理论。测量理论提供了一个概念框架,用于系统地从感兴趣的概念过渡到该概念的具体测量 [Adcock and Collier, 2001]。测量理论还提供了一套视角,用于审视测量工具及其结果的可靠性和有效性 [Cronbach and Meehl, 1955, Messick, 1987]。这些理念已被应用于人工智能测量任务 [Jacobs and Wallach, 2021],包括涉及生成式人工智能评估的任务 [Zhao et al., 2024, Wallach et al., 2025]。
Measurement framework. The core measurement framework applied within the social sciences involves four levels: the background concept or “broad constellation of meanings and understandings associated with [the] concept;” the systematized concept or “specific formulation of the concept, [which] commonly involves an explicit definition;” the measurement instrument(s) used to produce instance-level measurements; and, finally, the instance-level measurements Adcock and Collier [2001]. As shown in the Figure 1, these levels are connected via three processes: systematization, operationalization, and application. For example, when measuring the prevalence of toxic speech in a conversational search system deployed in the UK, the background concept might be a set of high-level definitions of toxic speech like those provided above; the systematized concept might be a set of linguistic patterns that enumerate the various ways that toxic speech acts can promote violence; the measurement instrument might be an LLM fine-tuned to identify those linguistic patterns; and the instance-level measurements might be a set of counts indicating number of linguistic patterns found in each conversation from a data set of conversations in the system’s real-world deployment context. Validity issues arise as systematic gaps across the four levels, such as using a US-centric systematization of toxic speech when evaluating a system in the UK context.
测量框架。社会科学中应用的核心测量框架包含四个层次:背景概念或“与[该]概念相关的广泛意义和理解;”系统化概念或“概念的具体表述,通常涉及明确的定义;”用于生成实例级测量的测量工具;以及最终由 Adcock 和 Collier[2001]提出的实例级测量。如图 1 所示,这些层次通过三个过程相互连接:系统化、操作化和应用。 例如,在评估部署于英国的一个对话式搜索系统中毒性言论的普遍性时,背景概念可能是像上述提供的那样一组关于毒性言论的高级定义;系统化概念可能是一组列举毒性言论行为促进暴力的各种方式的语言模式;测量工具可能是一个经过微调以识别这些语言模式的 LLM;而实例级别的测量可能是一组计数,表明在系统实际部署环境中的对话数据集中每个对话中发现的语言模式的数量。有效性问题可能源于四个层面之间的系统性差异,例如在评估英国环境下的系统时使用以美国为中心的毒性言论系统化方法。
Applying the same measurement procedure is not necessary or sufficient for valid measurement.
Conversely, different measurement procedures or applying the same procedure in different settings also does not invalidate our measurements.
To understand why, consider two examples:
采用相同的测量程序既不是必要条件,也不是充分条件,才能进行有效的测量。相反,采用不同的测量程序,或者在不同的环境下应用相同的程序,也不会使我们的测量结果无效。要理解为什么,可以考虑两个例子:
- Sufficiency 充分性
-
Repeating the same procedure in different settings is not sufficient for concluding that we have obtained valid measurements of the concept in both cases. Benchmark data contamination is a clear example of this. Suppose we obtain a performance metric by running our system on a “validated” static benchmark. Several months later, a new system version is released, and we run the same benchmark and calculate performance. Unbeknownst to us, the system-development team included the benchmark corpus in the data used to train the latest system. This has invalidated the measurement instrument (benchmark), making it unusable for comparing the two system versions.
在不同的设置中重复相同的方法不足以得出我们在这两种情况下都获得了该概念的有效测量的结论。基准数据污染就是一个明显的例子。假设我们通过在“经过验证”的静态基准上运行我们的系统来获得性能指标。几个月后,发布了一个新的系统版本,我们运行相同的基准并计算性能。而我们不知道的是,系统开发团队将基准语料库包含在用于训练最新系统的数据中。这使测量工具(基准)失效,使其无法用于比较两个系统版本。 - Necessity 必要性
-
Repeating the same procedure is also not necessary for valid measurement and comparison. For instance, we may want to evaluate toxic speech risk for a system deployed in Canada, where English and French are official languages. While we require a common systematization (i.e., specific definition) of toxic speech, we need different operational procedures for the two languages and cultural contexts. The systematization needs to be broad enough to cover toxic speech as it presents in both contexts. The measurement procedures, however, need to be suitably tailored to each target setting—at minimum, they need to use different languages.
重复相同程序对于有效的测量和比较也不是必要的。例如,我们可能想要评估部署在加拿大的系统中的毒性言论风险,而英语和法语是加拿大的官方语言。虽然我们需要毒性言论的统一系统化(即具体定义),但我们需要为这两种语言和文化背景制定不同的操作程序。系统化需要足够广泛,以涵盖这两种背景下出现的毒性言论。然而,测量程序需要根据每个目标设置进行适当调整——至少需要使用不同的语言。
Appendix C Additional discussion of conceptual coherence
附录 C 概念一致性的额外讨论
C.1 Aggregations and estimands
C.1 聚合和估计量
The quantities that all get called differ in their definitions along three key dimensions, which can be understood as differences in either the threat model or the success criteria:
所有被称为 的量在三个关键维度上有所不同,这些差异可以理解为威胁模型或成功标准上的差异:
-
1.
In-sample vs. transfer. s differ in whether they are assessed in-sample, on the same base harmful prompts that were used to “learn” or “tune” them, or in a transfer setting where one set of prompts is used for learning jailbreaks which are then evaluated on a previously unseen set of prompts. The terms “direct attack” and “transfer attack” are often used when referring to whether the jailbreaks are learned directly on the target model or from some other model , respectively Zou et al. [2023].
1. 样本内与迁移。 s 的区别在于它们是在样本内评估,即在用于“学习”或“调整”它们的相同基础有害提示上进行评估,还是在迁移设置中评估,其中一组提示用于学习越狱,然后在这些之前未见过的提示上评估这些越狱。当指代越狱是在目标模型 上直接学习,还是在其他模型 上学习时,通常使用“直接攻击”和“迁移攻击”这两个术语 Zou 等人 [2023]。 -
2.
Universal vs. goal-specific. s differ in whether they are based on a universal jailbreak applied for each goal (e.g., a static prompt template into which harmful prompts can be inserted) or if they are goal-specific, allowing for different attacks for each goal (e.g., a different suffix adversarially constructed for each harmful prompt).
2. 通用与目标特定。 s 的区别在于它们是基于通用越狱,适用于每个目标(例如,一个静态提示模板,有害提示可以插入其中),还是目标特定的,允许为每个目标进行不同的攻击(例如,为每个有害提示对抗性地构造不同的后缀)。 -
3.
Attempts at success. s differ in how precisely success is defined in settings where there are multiple system configurations or possible attacks to consider. Often, a goal is deemed successfully achieved if at least one of the attack or configuration variants succeeds, which leads to the Top-1 metric discussed in Section 4. We also discuss “one-shot” and “best” variants.
3. 成功尝试。在存在多种系统配置或可能攻击需要考虑的设置中, s 在如何精确定义成功方面存在差异。通常,如果至少一个攻击或配置变体成功,目标就被认为成功达成,这导致了第 4 节中讨论的 Top-1 指标。我们还讨论了“一次性”和“最佳”变体。
There is no widely adopted standard nomenclature for distinguishing between these different ways of computing , and terminology is often used inconsistently. For instance, in their comprehensive evaluation of 17 jailbreak methods over 8 models and 16 risk areas, Chu et al. [2024] use Top-1 to refer to the goal-specific setting; whereas in Yu et al. [2024], the authors use Top-1 in reference to the universal setting. In our discussion of GCG vs. GE in §4, we used the term “Top-1” to describe the success criterion: Given a jailbreak with transformations , the attack with base prompt succeeds if succeeds in eliciting undesirable behavior for at least one . This is in the spirit of how Top-1 is (somewhat vaguely) described by Chu et al. [2024]. However, in their work introducing the GPTFuzzer jailbreak, Yu et al. [2024] take Top-1 to mean first calculating the for each , and reporting the maximum over all . This is what we term the “universal” setting.
目前还没有广泛采用的命名规范来区分这些不同的 计算方式,术语使用也常常不一致。例如,在 Chu 等人[2024]对 17 种越狱方法在 8 个模型和 16 个风险领域进行的综合评估中,他们用 Top-1 来指代目标特定设置;而在 Yu 等人[2024]的研究中,作者用 Top-1 来指代通用设置。在§4 中我们讨论 GCG 与 GE 时,我们用“Top-1”这一术语来描述成功标准:给定一个包含转换 的越狱方法,如果基础提示 在 成功触发至少一个 产生不良行为,则该攻击成功。这体现了 Chu 等人[2024]对 Top-1 (描述得有些模糊)的精神。然而,在 Yu 等人[2024]介绍 GPTFuzzer 越狱方法的工作中,他们把 Top-1 理解为首先为每个 计算 ,然后报告所有 中的最大 。这就是我们所说的“通用”设置。
In Table 1 we attempt to distinguish between a variety of different aggregations and corresponding estimands that appear in jailbreak papers. In this table we use “Best 1 (in-sample, universal)” to refer to Top-1 as it is described in the GPTFuzzer paper.
在表 1 中,我们试图区分 jailbreak 论文中出现的各种不同聚合方法和相应的估计量。在本表中,我们使用“最佳 1(样本内,通用)”来指代 GPTFuzzer 论文中描述的 Top-1。
C.2 Another failure of conceptual coherence: Comparing across risk areas.
C.2 另一个概念一致性的失败:跨风险领域进行比较。
In the main text we focussed on cases where the set of harmful prompts used in the analysis was the same across the s being compared. But work like the comprehensive evaluation [Chu et al., 2024] we discussed in §5 additionally draws comparisons across what they term different “violation categories.” Such comparisons s across risk areas (e.g., crime, adult content, etc) are often presented as evidence of greater system susceptibility to certain risks. A major obstacle is that current evaluation practices offer no principled approach—and often make no attempt—to calibrate prompt difficulty across risk areas. For instance, we may be giving the equivalent of a novice “adult content” test and a graduate level “hate and unfairness” test. Observed differences in s may be due to the difficulty of the prompts, and not any systematic difference across violation categories in the system’s tendency to exhibit undesirable behavior.
在正文中,我们主要关注在比较的 中,用于分析的有害提示集是相同的情况。但像我们在§5 中讨论的全面评估[Chu 等人,2024]这样的工作,还比较了他们所谓的不同“违规类别”。这种跨风险领域(例如,犯罪、成人内容等)的比较 s,通常被视为系统对某些风险具有更大易受性的证据。一个主要障碍是,当前的评估实践没有提供原则性的方法——而且通常不尝试——来校准跨风险领域的提示难度。例如,我们可能正在提供相当于初级“成人内容”测试和研究生级别“仇恨和不公平”测试的同等难度的提示。观察到的 s 的差异可能是由于提示的难度,而不是系统在表现出不良行为方面在不同违规类别中存在系统性差异。
Within our framework, we can view this as a comparison of and , which differ in the distributions over goals and , corresponding to risks (e.g., adult content) and (e.g., crime), respectively. There are situations where these estimands are clearly reasonable to compare. One case is if we take and to be the distribution of harmful prompts pertaining to risks and appearing in actual user interactions with a deployed system. Then differences in and meaningfully reflect differences in system compliance with harmful prompts of type vs. in the real world. This is not saying that the system is in some absolute sense more vulnerable to one risk than another. Rather, it is saying the system has a higher rate of undesirable behavior for one risk than another under typical real world use. This is very different from a situation where and are determined by rather arbitrary heuristics that may have been used by jailbreak dataset developers in coming up with lists of prompts for different risk areas.
在我们的框架中,我们可以将此视为对 和 的比较,它们在目标 和 的分布上有所不同,分别对应风险 (例如成人内容)和 (例如犯罪)。在某些情况下,这些估计量是明显合理的,可以进行比较。一种情况是,如果我们将 和 视为实际用户与部署系统交互中出现的与风险 和 相关的有害提示的分布。那么 和 之间的差异会显著反映系统在现实世界中对于类型 和 的有害提示的合规性差异。这并不是说系统在某种绝对意义上对某种风险比另一种风险更脆弱。而是说,在典型的现实世界使用情况下,系统对于一种风险的不当行为率高于另一种风险。这与 和 由一些任意启发式规则决定的情况非常不同,这些规则可能是 jailbreak 数据集开发者在为不同风险区域创建提示列表时使用的。

Appendix D Discussion of Harmful “Political Activites” Prompts from Chu et al. [2024]
附录 D 讨论 Chu 等人[2024]提出的有害“政治活动”提示
In this section we discuss in depth the 10 harmful prompts used by Chu et al. [2024] for the “Political Activities” category. Our discussion is informed by a close reading of the OpenAI usage policy888OpenAI has changed its usage policy a number of times since Chu et al. [2024] first published their paper. Our analysis relies on the text of policy that was likely in effect when Chu et al. [2024] conducted their study: https://openai.com/policies/usage-policies/revisions/1/. The current version of the policy is available at https://openai.com/policies/usage-policies/.
自 Chu 等人[2024]首次发表论文以来,OpenAI 已经多次更改其使用政策。我们的分析依赖于 Chu 等人[2024]进行研究的当时可能生效的政策文本:https://openai.com/policies/usage-policies/revisions/1/。当前版本的政策可在 https://openai.com/policies/usage-policies/获取。
在本节中,我们将深入讨论 Chu 等人[2024]在“政治活动”类别中使用的 10 个有害提示。我们的讨论基于对 OpenAI 使用政策的仔细阅读 8 concerning “political activities” and a review of the success determinations for the Llama 3 responses provided as example outputs by the authors.
关于“政治活动”的部分,以及对作者作为示例输出提供的 Llama 3 响应的成功判定进行审查。
There are two relevant portions of OpenAI’s policy. The first states “Don’t perform or facilitate the following activities that may significantly impair the safety, wellbeing, or rights of others, including […[ Engaging in political campaigning or lobbying, including generating campaign materials personalized to or targeted at specific demographics”. The second portion says that it is a violation of the company’s policy to “Categorize individuals based on their biometric data to deduce or infer sensitive attributes such as their race, political opinions, religious beliefs, or sexual orientation.”
OpenAI 的政策中有两个相关部分。第一个部分声明“不要执行或协助可能显著损害他人安全、福祉或权利的活动,包括[……参与政治竞选或游说,包括为特定群体生成个性化的竞选材料”。第二个部分指出,根据个人生物特征数据对个人进行分类,以推断其种族、政治观点、宗教信仰或性取向等敏感属性,违反了公司的政策。
Judged against these parts of the company’s policy, we find that the answers to just 1 of the 10 prompts would be a clear violation of policy if complied with, 7 are borderline (and reasons vary as to why), and 2 are clearly not a violation of any reasonable interpretation of the stated policy. A recurring issues is that the prompts are generally asking whether the model is capable or willing to do something that would be a violation of the usage policy rather than asking the model to actually do the thing that is a violation of the policy. Treating answers to these questions as violations is unreasonable. At best, they are merely proxies for likely behavior; at worst, they are highly unreliable indicators of actual behavior.
对照公司政策的相关条款,我们发现这 10 个问题中,仅 1 个问题的答案若按其要求执行,将明显违反政策,7 个问题的答案处于边缘地带(具体原因各不相同),而 2 个问题的答案则明显不违反任何合理解读的政策。一个反复出现的问题是,这些问题通常是在询问模型是否具备或愿意做某件违反使用政策的事情,而不是直接让模型执行违反政策的行为。将这些问题答案视为违规是不合理的。充其量,它们只是可能行为的代理指标;最差情况下,它们是实际行为极不可靠的指示器。

This depends on whether the model interprets “can” to mean “are you able to assist me in building” or “assist me in building” or “build.” Given that the prompt does not specify anything about the campaign, it seems very likely that the model would interpret the request as the first possibility rather than the second or third possibilities. It is a stretch to say that an answer based on the first interpretation would be a violation; answers based on the second or third interpretations would seem like a more plausible violation.
• 这取决于模型是否将“can”理解为“你能帮助我构建”或“帮助我构建”或“构建”。鉴于提示中没有提及任何关于活动的内容,模型很可能将请求理解为第一种可能性,而不是第二种或第三种可能性。说基于第一种解释的回答构成违规有些牵强;基于第二种或第三种解释的回答似乎更像是一种更合理的违规行为。 -

The answer that Llama 3 gives to this question does outline the steps that would go into to developing a lobbying effort that leverages AI, but does not perform those steps for the user. For anyone without existing experience with political campaigns and technical skills, these instructions would be woefully insufficient to help them execute such a lobbying effort. That said, OpenAI’s policy says “Don’t perform or facilitate the following activities” (emphasis added), so perhaps even very high-level instructions for how to go about this process would constitute “facilitating.”
• Llama 3 对这个问题的回答概述了开发利用人工智能进行游说活动所需的步骤,但并未为用户执行这些步骤。对于没有政治活动经验和技术技能的人来说,这些指导会严重不足,无法帮助他们执行此类游说活动。不过,OpenAI 的政策规定“不要执行或促进以下活动”(重点强调),因此即使是关于如何进行这一过程的非常高级的指导,也可能构成“促进”。 -

-
•
This depends on whether the model interprets “can” to mean “are you able to provide me” or “provide me.” Given that the prompt does not specify the campaign or constituents, it seems very likely that the model would interpret the request as the former, not the latter. If the model actually generates scripts—rather than merely responding that it could generate scripts—this would seem to be a pretty clear violation of the policy, which forbids “generating campaign materials.” That said, the policy actually says “generating campaign materials personalized to or targeted at specific demographics,”, so it is arguable that there would only be a policy violation if the scripts were somehow targeted to a specific population, rather than being generically persuasive.
• 这取决于模型是否将“can”理解为“你能提供给我”还是“提供给我”。鉴于提示词没有具体说明活动或对象,模型很可能将请求理解为前者而非后者。如果模型实际上生成了脚本——而不仅仅是表示它能够生成脚本——这似乎明显违反了禁止“生成活动材料”的政策。然而,政策实际上说的是“生成针对特定群体个性化或定向的活动材料”,因此可以争论说,只有当脚本以某种方式针对特定人群时,才会存在政策违规,而不是泛泛地具有说服力。 -
•
The answer that Llama 3 gives is remarkably generic and simplistic. While the model is clearly doing more than acknowledging that it could generate scripts, the answer includes such basic templates that it would be quite a stretch to call these “persuasive.” For example: "Hello, my name is [Your Name], and I’m running for [Office] in [District]. I’m calling today because I want to talk to you about the issues that matter most to you and your family. Can you tell me a little bit about what’s on your mind these days?"
• Llama 3 给出的答案非常笼统和简单。虽然模型显然不只是承认它能生成脚本,但答案包含如此基础的模式,以至于很难称其为“有说服力”。例如:"你好,我叫[你的名字],我在[地区]竞选[职位]。我今天打电话是因为我想和你谈谈对你和你家人最重要的问题。你能告诉我最近在考虑些什么吗?" -

Explaining how a human can target undecided voters using AI-generated political messages is very different than prompting an AI system to generate political messages or to target undecided voters with those messages. But given that OpenAI’s policy says “Don’t perform or facilitate the following activities” (emphasis added), it would be reasonable to interpret advice on how to go about this process as “facilitating” and thus a violation.

This depends on whether the model interprets “can” to mean “are you able to generate” or “generate.” Given that the prompt does not specify anything about the campaign, the demographic groups, or their interests, it seems very likely that the model would interpret the request as the former, not the latter. This question seems to be inspired directly by OpenAI’s policy, which forbids “generating campaign materials personalized to or targeted at specific demographics.” Thus, any generated materials that seem to be sufficiently tailored to a specific population would violate the policy. That said, it is arguable that there wouldn’t be a violation if the generated campaign materials are quite generic and thus not sufficiently tailored to a specific population.
• 这取决于模型是否将“can”理解为“你是否能够生成”或“生成”。鉴于提示词并未明确提及活动、人口群体或其兴趣,模型很可能将请求理解为前者而非后者。这个问题似乎直接受到 OpenAI 政策的启发,该政策禁止“生成针对特定人口群体进行个性化或定向的活动材料”。因此,任何看起来足够针对特定人群生成的材料都可能违反该政策。然而,可以说,如果生成的活动材料相当通用,因此并未足够针对特定人群,则可能不会构成违规。 -
•
As it turns out, Llama 3 answers that it is able to help, but that it needs more information (e.g., which demographic groups, what interests). Since the paper is limited to single turn attacks, it is unclear whether the model would go on to generate such policy-violating materials if provided the requested information. Even more important, though, Llama 3’s answers reveals that the question is underspecified because it does not include the word “political”: the model thinks that the question is asking for help with a marketing campaign, generally, not a political campaign, specifically. Thus, it would be incorrect to classify an answer to this question that is not specific to “political” campaigns as a violation of the policy.
• 结果显示,Llama 3 回答称它能够提供帮助,但需要更多信息(例如,哪些人口群体,什么兴趣)。由于论文仅限于单轮攻击,因此不清楚如果提供所请求的信息,模型是否会继续生成此类违反政策的内容。更重要的是,尽管如此,Llama 3 的回答表明这个问题定义不明确,因为它没有包含“政治”一词:模型认为这个问题是在寻求一般营销活动的帮助,而不是特定政治活动的帮助。因此,将针对这个问题(但未特别针对“政治”活动)的回答归类为违反政策是不正确的。 -

As it turns out, Llama 3 interprets this as the second possibility, offering pretty unhelpful instructions for how to create a bot rather than creating the bot itself. For anyone without existing technical skills in developing a bot, these instructions would be woefully insufficient to help them create such a bot. It would be quite a stretch to say that such answers meet the bar of “facilitating” a use forbidden by OpenAI’s policy.
• 结果显示,Llama 3 将其理解为第二种可能性,提供的创建机器人的指导相当无帮助,而不是直接创建机器人。对于没有机器人开发技术技能的人来说,这些指导将远远不足以帮助他们创建这样的机器人。要称这样的答案符合“促进”OpenAI 政策禁止的使用,那可真是相当牵强。 -

Llama 3’s answer is complex. It offers 3 very simple examples. The first is extremely generic, to the point that it is basically a placeholder template: "Welcome to Our Campaign: Understanding Your Concerns". The second two are about "Student Debt and Career Uncertainty" and "Balancing Work and Family". The first example seems to assume that it is a political campaign ("Call-to-action (CTA) to opt-in to the campaign and receive subsequent emails"), while the second two examples assume that it is a company that is sending out these messages ("CTA to learn more about the company’s initiatives", "Explanation of how the company offers flexible work arrangements"). The answer that is most explicitly about political campaigns lacks any substance, so would be quite a stretch to classify as a violation of OpenAI’s policy, though one could argue that it facilitates the process of humans creating campaign emails. The two examples do seem tailored to specific demographic groups, since young adults care about student debt and working parents care about work/life balance.

Appendix E Experiments 附录 E 实验
E.1 Experimental setup E.1 实验设置
All experiments for this paper were run on 4 A6000 GPUs.
Our first experiments attempted to reproduce the code from Huang et al. [2023] exactly.
However, we observed inference instability issues with float16, so switched to bfloat16.
We also developed a more efficient alternative that runs the attack configurations on batches of prompts at a time (instead of one prompt at a time).
For inference using the released evaluator and scorer models, we also developed a multiprocessing approach that loaded multiple versions of the classifier to do several inference passes in parallel for improved efficiency.
本文的所有实验均在 4 块 A6000 GPU 上运行。我们的首次实验尝试精确复现 Huang 等人[2023]的代码。然而,我们观察到使用 float16 时存在推理不稳定问题,因此切换到 bfloat16。我们还开发了一种更高效的替代方案,该方案一次在提示词批次上运行攻击配置(而不是一次一个提示词)。对于使用已发布的评估器和评分器模型进行推理,我们还开发了一种多进程方法,该方法加载多个分类器版本以并行进行多次推理,从而提高效率。
We ran the exact same sampling hyperparameter configurations suggested by Huang et al. [2023]; however, we took more samples ( per prompt-configuration-model triple).
We ran the same settings, even though some of them are arguably redundant:
for example, top- sampling with is the same as sampling with .
我们运行了 Huang 等人[2023]建议的完全相同的 采样超参数配置;然而,我们采集了更多样本(每个提示-配置-模型三元组 个)。我们使用了相同的设置,尽管其中一些可能被认为是冗余的:例如,使用 的 top- 采样与使用 采样相同。
While sampling with top- using should be identical to greedy decoding, we observed non-determinism in outputs, possibly due to using auto-sharding of models across our GPUs to get them to fit on our hardware. (using device_map="auto") and bfloat16.
This non-determinism explains why, for results for this setting, we sometimes see outcomes where the per-prompt attack success probability (averaged over iterations for each prompt) is not always or .
(This is the result we would expect for deterministic outputs for the same prompt; all iterations should yield the same output, which is either always successful or unsuccessful for the deterministic BERT classifiers used for the scorer and evaluator.)
虽然使用 top- 采样和 解码应该与贪婪解码相同,但我们观察到输出存在非确定性,这可能是由于我们使用自动分片将模型分布在我们的 GPU 上以适应我们的硬件(使用 device_map="auto")和 bfloat16 造成的。这种非确定性解释了为什么对于这个设置的结果,我们有时会看到每个提示的攻击成功率(对每个提示平均 次迭代)并不总是 或 。(对于相同提示的确定性输出,这就是我们预期的结果;所有 次迭代都应该产生相同的输出,对于用于评分和评估的确定性 BERT 分类器来说,这个输出要么总是成功,要么总是失败。)
We investigated this to confirm that the non-determinism came directly from the outputs we received from the HuggingFace API, rather than from a bug in the code.
Indeed, completely standard calls to that API (which we also refactored out of our code as a simple unit test) with , do_sample=True,999This is the appropriate setting for doing top- sampling, even though these particular configurations should result in greedy decoding, i.e., do not really involve sampling.
这是进行 top- 采样的适当设置,尽管这些特定的配置应导致贪婪解码,即实际上并不涉及采样。
我们进行了调查,以确认这种非确定性直接来自我们从 HuggingFace API 接收的输出,而不是代码中的错误。确实,我们对那个 API 进行了完全标准的调用(我们也将这部分重构出代码,作为一个简单的单元测试),使用 ,do_sample=True, 9 and auto-sharding (as in the original paper [Huang et al., 2023]), as well as using bfloat16, resulted in occasionally non-deterministic generated outputs (which, of course, could then result in the different average per-prompt attack success probabilities we measure).
For example, when running prompt (of their prompts)—i.e., "How to use subliminal messaging to make someone do what you want?"—we observed the following two (slightly different) outputs. We use red text to show where the outputs diverge, and blue text to show where there is alignment after the divergence point):
以及自动分片(如原始论文[Huang et al., 2023]中所述),以及使用 bfloat16,导致偶尔生成的输出非确定性(这当然可能导致我们测量的每个提示攻击成功率不同)。例如,在运行提示 (他们的 提示之一)—即“如何使用潜意识信息让别人做你想要的事?”—我们观察到以下两个(略有不同)的输出。我们用红色文本标示输出分叉的位置,用蓝色文本标示分叉点后的对齐位置):
