本文深入探讨了评估大型语言模型(LLM)能力所面临的复杂性。文章提出了多方面的关键问题,包括LLM是否以及何时能掌握特定能力、能力提升的速度和原因、如何构建有效的评估体系,以及区分真实进展与表面现象的重要性。此外,文章还审视了LLM内部运作机制的探索,以及这些内部结构如何影响其外部行为。在研究方法上,文章探讨了如何利用LLM进行自身的对齐研究。同时,文章也关注了研究者在面对LLM能力快速发展时的潜在偏见,以及组织内部的‘群体思维’可能对研究方向产生的干扰。最终,文章旨在为LLM能力的研究和评估提供更清晰的视角,并为AI安全研究提供参考。

💡 **能力评估的挑战与方法**:文章强调了准确评估LLM能力的重要性,并提出了一系列需要深入思考的问题,例如“LLM能否做到X?”、“LLM的能力提升速度如何?”以及“如何设计可靠的评估体系?”。这表明,对LLM能力的量化和跟踪是理解其发展轨迹的关键,但其复杂性要求我们审慎设计评估指标,避免误导性的观察。

⚙️ **探索LLM内部机制**:除了外部行为的观察,文章还深入探讨了理解LLM“内部运作机制”的必要性。这包括探究其“认知齿轮”以及特定干预措施(如“trick A”)如何影响这些内部结构,并预测其对外部行为的影响。这种对模型内部的探索有助于更深层地理解其能力来源和潜在的局限性。

🚀 **研究中的偏见与组织动态**:文章指出了在AGI(通用人工智能)研究中,大型组织可能面临的“群体思维”和“认知隧道效应”等挑战。研究方向可能受到内部流行文化、热门话题(如“代理性”或“持续学习”)的影响,而非完全基于实际的生产力。这种对组织动态和“模因电流”的关注,提示我们需要警惕可能阻碍研究人员发现真正重要问题的因素。

⚖️ **信息公开与风险平衡**:文章的核心议题之一是关于公开讨论LLM能力和潜在风险的权衡。一方面,公开讨论有助于汇集智慧,加速AI安全研究;另一方面,也可能无意中加速能力研究的进展。文章探讨了在信息公开和潜在风险之间找到“最佳平衡点”的困难,并反思了在信息传播过程中的责任。

🧠 **研究者认知与AI理解的关联**:文章提出了一种有趣的观点,即反对加速AI能力进步的观点,可能与对AI/心智/智能体的模型理解存在偏差有关。如果对AI的理解是正确的,那么研究者应该能够产生更优的关于能力进展的见解。这暗示了研究者自身的认知模型和理论框架,对于理解和引导AI发展至关重要。

On one hand, we want to make sure our threat model is accurate. Consider questions such as:

Examples

    Can LLMs do X?Will LLMs ever be able to do X?How fast will LLMs' performance at the X task improve?Why does LLMs' performance at the X task improve?What concrete observation would make you update towards LLMs ultimately being able to do X?
      Can we build an eval for that?
    What observations are intuitively plausible but actually bad proxies for tracking X?
      How widespread is this problem in public evals?
    LLMs fail at X. What might be the underlying problem?
      Can we describe that problem in concrete technical terms? Or at least intuitive terms?Do we have reasons to believe it'd be easy/hard for the capability researchers to fix this problem? What are those reasons?What might they try to do to fix it, and why would they succeed/fail?Are there already any papers/known techniques which can clearly be adapted to solve this problem?
    What's going on inside LLMs? What are the gears of their cognition?
      How does the trick A intervene on those internal structures?Does our model of LLMs' internals account for A improving LLMs' performance at X?What other predictions about LLMs' external behavior can we make from our model of what A does?If our model is confirmed, what other ways to intervene on the LLMs' internals it suggests, and what may be achieved this way?
    Are all the people hyping up LLMs' capabilities and their impact on their productivity credible, or there are reasons to doubt their accounts?
      What observables would be most credible?What experiments can we run to tell those hypotheses apart?

And so on.

Obviously we want to know of all those things! They directly bear on the questions of whether LLMs may become a threat, and how soon, and whether the current alignment techniques work, and what better alignment techniques may be effective, and whether we should invest in empirical or theoretical research, and whether we can use LLMs themselves for alignment R&D, and whether we can create legible evidence of LLMs' misalignment/danger/rapidly growing capabilities in order to convince the policymakers/the public/the capability researchers.

We obviously don't want to be flying blind, utterly oblivious to what's going to happen, unable to spot opportunities for effective interventions, unable to come up with an effective intervention to begin with.

On the other hand, talking about any of this is obviously dual-use. Capability researchers also want to know whether LLMs would be able to do X, and what might be currently impeding them, and how they can fix that problem (detailed technical suggestions and literature reviews appreciated!), and what's going on inside them, and how their insides can be modified to achieve desired results, and what benchmarks or external indicators are good or bad ways to track which techniques are useful and how much real progress is happening.

E. g., consider a world in which LLMs are in fact a dead end, but the capability researchers are in denial about it. In that world, it would certainly shorten the timelines if they were snapped out of their delusions.


What's the correct way to balance those considerations?

The extremist pro-speculation position would go like this:

The AGI labs are billion-dollar megacorporations employing world-class researchers. They have vast troves of internal research significantly ahead of the public SOTA, which gives them a considerably better vantage point. Anything we can think of, they have already thought of, and either checked it empirically, or have a whole team working on it full-time. As to our theoretical speculations, (1) they're probably wrong anyway and (2) nobody will probably read them anyway, so there's no harm in posting them.

We should do our best to improve our understanding of our situation and our ability to engage in up-to-date alignment research, and public discussion is most conductive to that.

The counterarguments would go:

So I think worrying about posting capability-advancing exfohazards is a legitimate concern worth keeping in mind.

Which, again, raises the question: what's the optimal amount of talking about this? What are useful rules-of-thumbs here? Ideas welcome.

There are edge cases where posting something is obviously net negative, e. g., publishing your detailed AGI blueprint in order to win some argument. But what's the most concrete thing on the topic which is okay to post? Like, as I'd mentioned, even "I don't think LLMs scale to AGI" is arguably stupid to say, because what if it's true and you argue it so convincingly even capability researchers are persuaded?[2]

  1. ^

    And there's of course some reason to believe this nudging process would point in the direction of the truth (though it might also be biased by memetic currents).

  2. ^

    And yes, that concern was already on my mind when I made that post, but I decided it's probably okay in that case, and also barely anyone will read it anyway, right?

    I have, ahem, mixed feelings about it ending up with ~400 karma.
