Few-Shot Demonstrations Elicit the Use of In-Context World Representations in LLMs

Large language models (LLMs), when acting as agents, are expected to take observed data in context, infer the latent state space underlying the world, and leverage it for downstream prediction. However, prior work demonstrated that LLMs struggle to use representations learned in context on a graph tracking task, where...

In-Context Neurofeedback: Can LLMs Control Their Internal Representations through Privileged Access?

The neurofeedback paradigm for LLMs is redesigned so that the control target satisfies the privileged access requirement, which is closer to neurofeedback experiments in human cognitive neuroscience and indicates that rigorous assessments of metacognition in LLMs require evaluation methods that demand privileged access...

Visual Access Boundaries in Vision-Language Model Reasoning

A symbolic-attribute oracle shows that CoT can improve counting once ground-truth attributes are supplied as text, while a single-object probe-vs-decode check shows that hard attributes can be linearly recoverable from hidden states yet difficult for the model itself to output.

Zipping the Thought: When and How Compressed Reasoning Data Works in LLM Post-Training

A taxonomy of CoT is proposed consisting of Explicit CoT, which outputs all operations without aggregation, Composed CoT, which combines multiple operations into a single step, and Implicit CoT, which omits intermediate operations.
