GPT-6 Astra can edit Qwen3.5-0.8B’s weights and raise its MATH-500 from 7.9% to 48.1%, without gradients or retraining.
摘要
alphaXiv 转述 MIT 的一篇博客，称 GPT-6 Astra 能在不计算梯度、不重新训练的情况下直接读取并编辑 Qwen3.5-0.8B 的权重，使其 MATH-500 成绩从 7.9% 提升到 48.1%。
摘要由模型根据原文撰写，以原文为准。

GPT-6 Astra can edit Qwen3.5-0.8B’s weights and raise its MATH-500 from 7.9% to 48.1%, without gradients or retraining.
“Sparks of Weight-Space Programming”
This blog from MIT asks whether LLMs can read and edit neural network weights directly, much like code.
In Qwen, Astra traced repetitive reasoning loops to a direction written by two MLP layers, then edited the weights to suppress it.
With 50 batches of forward-pass feedback, the fix also raised instruction following from 21.0% to 62.3%
