Breakthrough hallucination research, Sonnet 4.6's identity crisis, Karpathy on the coding agent inflection point, and Perplexity's new multi-model computer system.

Tsinghua researchers conducted a systematic investigation into "H-Neurons"—specific neurons in LLMs that cause hallucinations. They identified these neurons, showed deactivating them reduces hallucination rates significantly, and traced their origins to noisy training data.

A concrete, mechanistic understanding that could lead to architectural solutions rather than the usual band-aids of RLHF or output filtering.

Quick hits — benchmarks, policy, and local model tools.

Update: Hegseth Sets Friday Deadline for Anthropic on AI Safeguards Following yesterday's coverage, Defense Secretary Hegseth has given Anthropic a specific ultimatum: strip Claude's safety guardrails by Friday or face government retaliation.

Update: Qwen 3.5 Tested on 70 Real Repos — Craters on Hard Tasks APEX benchmark tested all Qwen 3.5 models and Codex 5.3 on 70 real codebases. Qwen 3.5 significantly underperforms on hard coding tasks despite strong benchmark numbers elsewhere.

Google's Aletheia Math Agent Solved 6/10 FirstProof Problems Google submitted Aletheia's answers before official release. All prompts and model answers posted on GitHub. A significant step in AI mathematical reasoning.
