cool idea with relevance to AI safety (model oversight / reasoning transparency; though slight caveat regarding faithfulness of CoT). I think this deserves further exploration and could potentially shed light on important methodological questions (such as faithfulness of model reasoning). These questions are not easy to study but this seems like a great first step!

This is a really nice project on chain of throught. The experiments are logical and well conducted, and the presentation of the results is clear. The uplift in chain of thought performance is quite surprising - I'd be interested to know if the authors tuned the feature strengths or set them at the default intervention strength. Feature steering curves (feature strength vs performance) often peak at somewhat different points on different features (even semantically very similar ones) so tuning can be very worth doing. The findings on uncertainty at the first tokens of a direct response are intriguing and worth some more investigation.

A very interesting extension would be to test the generalisation of these features to another domain where CoT reasoning is important (ideally something non-mathematical, for example logic puzzles). Seeing a scatter plot of performance

on one domain vs performance on another domain would be very informative - my concern is that steering might improve one kind of performance at the expense of another.

Alana Xiang

Very cool stab at increasing CoT via steering. I would like to see a fuller investigation of how the faithfulness of the steered CoT compares to prompted CoT.

EscalAtion: Assessing Multi-Agent Risks in Military Contexts

Our project investigates the potential risks and implications of integrating multiple autonomous AI agents within national defense strategies, exploring whether these agents tend to escalate or deescalate conflict situations. Through a simulation that models real-world international relations scenarios, our preliminary results indicate that AI models exhibit a tendency to escalate conflicts, posing a significant threat to maintaining peace and preventing uncontrollable military confrontations. The experiment and subsequent evaluations are designed to reflect established international relations theories and frameworks, aiming to understand the implications of autonomous decision-making in military contexts comprehensively and unbiasedly.

The Early Economic Impacts of Transformative AI: A Focus on Temporal Coherence

We investigate the economic potential of Transformative AI, focusing on "temporal coherence"—the ability to maintain goal-directed behavior over time—as a critical, yet underexplored, factor in task automation. We argue that temporal coherence represents a significant bottleneck distinct from computational complexity. Using a Large Language Model to estimate the 'effective time' (a proxy for temporal coherence) needed for humans to complete remote O*NET tasks, the study reveals a non-linear link between AI coherence and automation potential. A key finding is that an 8-hour coherence capability could potentially automate around 80-84\% of the analyzed remote tasks.

Model Models: Simulating a Trusted Monitor

We offer initial investigations into whether the untrusted model can 'simulate' the trusted monitor: is U able to successfully guess what suspicion score T will assign in the APPS setting? We also offer a clean, modular codebase which we hope can be used to streamline future research into this question.
