Claim: GPT-6 edits Qwen3.5-0.8B weights directly, 6x math gain with no training

lateinteraction · x · 2026-11-03

A widely shared claim dubbed "Weight-Space Programming": GPT-6 Astra was asked to edit Qwen3.5-0.8B's weights to improve math. It reportedly changed only 0.016% of weights, fixing the small model's reasoning loops, boosting math up to 6x and instruction following 3x — no gradients or training involved.

Retweeted with commentary that "2027 will be the year of agentic interp." Note: the claim involves model names that don't officially exist yet, and the related tech report was reportedly rejected by arXiv moderators — treat as unverified.
