[AINews] LLMs can read & write neural network weights: "Weight Space Programming" cuts Autoresearch out of the RSI loop

AINews issue for 31 October to 2 November 2026 from Latent Space. It leads with "Weight Space Programming" (Takehi et al., with Alex Zhang), where a frontier LLM reads and edits small models' weights without training. The recap also covers DeepSeek's super-agent harness, the SemiAnalysis GDPx benchmark, quantized local MoE models and Reddit skepticism about the Qwen3.5-0.8B MATH-500 edit. The page was truncated, so the final part is not covered.
