Researcher reports GPT-6 Astra edited Qwen3.5-0.8B weights to improve math

Researcher @rikiyatakehi reports a Weight-Space Programming experiment in which GPT-6 Astra edited the weights of Qwen3.5-0.8B to improve its math performance.

The report is the only source describing the experiment in the reporting provided.

A separate post from roon (@tszzl) on November 2, 2026 argues that neural networks should be designed and not grown. That post gives no figures, product names, or evidence, and does not refer to the experiment.
