## Summary

Researchers tested a method called Weight-Space Programming, in which the GPT-6 Astra language model edits or writes the raw weights of other AI models instead of retraining them. On Qwen3.5-0.8B, changing 0.016 percent of the weights raised MATH-500 accuracy from 7.9 to 48.1 percent, though thinking loops were not fully eliminated. The researchers say the method cannot add skills a model fundamentally lacks.

## Why it matters

The source compares weight-space programming with conventional retraining, showing where targeted weight edits improved a model and where they could not add missing skills.
