MIT CSAIL researchers say GPT-6 Astra fixed Qwen3.5-0.8B by editing 0.016% of its weights, without training
In a blog post the authors call very early results, GPT-6 Astra read raw weights, traced Qwen's reasoning loops and patched them by hand, lifting MATH-500 from 7.9% to 48.1% and IFEval 3x; it is not peer-reviewed.
