A preprint finds a shared internal direction that points language models to the first, second or later fact in a passage. Moving a question along that direction can change which fact the model retrieves.

A preprint finds that much of the benefit from an agent's history survives after its past actions are shuffled. Explicitly pairing each action with its result improves task completion.

Context Language Models replace an append-only transcript with a file the model can rewrite, delete and reorder. The authors report better long-task accuracy with less repeated computation after training the editing policy.

Today's remaining AI news covers an unusual hybrid model, spatial-memory and honesty studies, community measurements, agent security incidents, EU watermarking and practical talks.

A preprint adapts a clinical spatial-memory test for 16 vision-language models. All of them can recognise a landscape from the angle they studied, but most fall to guessing once the camera moves.

A preprint tests eight published probes on language models playing characters who reject basic facts. Many fail once true and false answers share the same prompt, and a probe trained to separate truth from obedience holds up.

A controlled study finds that one sentence of confidence or doubt can sharply change whether a reasoning model calls a tool, but the changes rarely target the problems where help is needed.

An interpretability study finds the same abstraction, induction and retrieval pathway before few-shot accuracy rises, suggesting demonstrations energise existing machinery instead of building a new algorithm.

Speaker diarisation, model-cognition papers, local projects, prompting practices, community tests and the day's safety and policy developments.

A controlled preprint separates detecting an activation change from reporting its location. The experiment uses fixed input text and scores answers without an AI judge.

A small trained intervention sharply improves Qwen3-8B on synthetic reference chains. The preprint traces the change to how middle layers pass information between lines.
