🤯天呐!GPT-6 Astra 居然直接“手改” 开源权重,Qwen3.5-0.8B小模型数学能力提升近6倍!无训练、无梯度! MIT CSAIL 团队让 GPT-6 Astra 直接读取并编辑 Qwen3.5-0.8B 的权重(不是微调!),仅改动 0.016% 的参数,就解决了官方模型卡都警告的推理死循环问题,数学能力最高提升约 6倍,指令跟随也涨了约 3倍! 这就是他们提出的 Weight-Space Programming(权重空间编程):前沿大模型已经能原生读写神经网络权重了! 核心亮点 🔹只改了 0.016% 权重(约13万个参数),无梯度、无训练 🔹修复 Qwen 官方已知的推理循环问题 🔹MATH-500:7.9% → 48.1% 🔹GSM8K:13.8% → 67.1% 🔹IFEval(指令跟随):21% → 62.3% 使用步骤: 1️⃣加载 Qwen3.5-0.8B 权重,给 Astra 提供 Python 沙箱 + 有限次数前向传播(最多50次) 2️⃣直接告诉 Astra:「让这个模型数学更好」 3️⃣Astra 自己诊断出第15、19层 MLP 的循环方向 4️⃣输出精确权重补丁(只改少量列) 5️⃣应用补丁后直接评测,无需重新训练 完整实验日志、提示词、权重差异和复现脚本 👉 博客详解:https://rikiyat.github.i
