LLM 0.37 and the AI-Reviewed AI PR

Simon Willison's LLM CLI hit 0.37 on November 2, adding gpt-6.1 models, a simpler OpenAI-compatible endpoint setup command, and multimodal embeddings. The more interesting note is that nearly all 12 contributing authors used AI assistance, and Willison uses Opus 5.5 or GPT-6 Astra to triage those submissions — a small but clear snapshot of where open source maintenance is now.

An LLM Fixes Another LLM's Weights

A blog post from this weekend describes using GPT-6 Astra to diagnose and edit the weights of Qwen3.5-0.8B without gradient descent, raising MATH-500 accuracy from 7.9% to 48.1% by removing a single looping direction from two MLP layers. It's early and constrained, but the concept of an LLM doing targeted surgical weight editing is new territory.
