Reinforcement Learning with Comparative Evidence for Social Intelligence

Developing socially intelligent AI remains heavily dependent on human-annotated data, limiting the scale and breadth of social understanding models can acquire. Methods that derive training signals from unlabeled data offer a path beyond this dependence, but social predictions lack the verification oracles available in...

There Is More to Refusal in Large Language Models than a Single Direction

This work uncovers a structured internal representation of refusal in large language models: a reusable core of shared refusal latents supplemented by style- and domain-specific latents, and clarifies the limits of linear interpretability for aligned model behavior.

Latent Mechanisms of Language Control in Multilingual Language Models

A comparative study of three methods that identify language-controlling latents in cross-layer transcoders: activation value-based selection (ValSel), activation frequency-based selection (FreqSel), and LLM-generated latent annotation-based selection (AnnSel) finds all three effectively manipulate generation language.
