this is huge
researchers found that the latest AI models can surgically edit another model's weights to improve it. without re-training it.
if this scales, things are about to go crazy
made a short video to explain

We asked GPT-6 Astra to edit Qwen3.5-0.8B weights to improve math.
It directly changed only 0.016% of weights, fixing 0.8B's reasoning loops & improving math up to 6x and even instruction following 3x, without gradients or training.
We call this Weight-Space Programming: frontier LLMs can now natively read/write neural network weights! 🧵
