Summary

A tweet criticizes a viral claim about 'Weight-Space Programming' where GPT-6 Astra supposedly edits Qwen3.5-0.8B weights to boost math performance, noting the results lack competent baselines and the Qwen result is mere bug fixing, while acknowledging that models reading/writing weights in toy problems is a real trend worth watching.

Rikiya Takehi (@rikiyatakehi): 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:
