摘要:
可信的能力评估对于确保 AI 系统的安全性至关重要,并且正成为 AI 监管的关键组成部分。然而,AI 系统的开发者或 AI 系统本身可能有动机让评估结果低估 AI 的实际能力。这些相互冲突的利益导致了沙袋行为问题,我们将其定义为在评估中策略性低报表现。本文评估了当代语言模型(LMs)的沙袋能力。我们提示前沿语言模型,如 GPT-4 和 Claude 3 Opus,在危险能力评估中选择性低报表现,同时在一般(无害)能力评估中保持表现。此外,我们发现模型可以在合成数据集上被微调,以隐藏特定能力,除非收到密码。这种行为可泛化到高质量的留出基准测试,如 WMDP。另外,我们表明前沿模型和较小模型都可以通过提示或密码锁定来瞄准能力评估中的特定分数。我们在密码锁定模型以模仿较弱模型给出的答案方面取得了中等程度的成功。总体而言,我们的结果表明能力评估容易受到沙袋行为的影响。这一脆弱性降低了评估的可信度,从而削弱了关于先进 AI 系统开发和部署的重要安全决策。
英文摘要:
Trustworthy capability evaluations are crucial for ensuring the safety of AI systems, and are becoming a key component of AI regulation. However, the developers of an AI system, or the AI system itself, may have incentives for evaluations to understate the AI's actual capability. These conflicting interests lead to the problem of sandbagging, which we define as strategic underperformance on an evaluation. In this paper we assess sandbagging capabilities in contemporary language models (LMs). We prompt frontier LMs, like GPT-4 and Claude 3 Opus, to selectively underperform on dangerous capability evaluations, while maintaining performance on general (harmless) capability evaluations. Moreover, we find that models can be fine-tuned, on a synthetic dataset, to hide specific capabilities unless given a password. This behaviour generalizes to high-quality, held-out benchmarks such as WMDP. In addition, we show that both frontier and smaller models can be prompted or password-locked to target specific scores on a capability evaluation. We have mediocre success in password-locking a model to mimic the answers a weaker model would give. Overall, our results suggest that capability evaluations are vulnerable to sandbagging. This vulnerability decreases the trustworthiness of evaluations, and thereby undermines important safety decisions regarding the development and deployment of advanced AI systems.
