Astra can read and write weights to improve Qwen

AI-generated summary

Researchers have developed 'Weight-Space Programming,' enabling LLMs like GPT-6 Astra to directly read and modify neural network weights. Astra demonstrated the ability to identify a network's purpose from its weights alone, fix critical errors, and even write new, high-performing game-playing networks from scratch. This technique significantly improved Qwen3.5-0.8B's math capabilities by directly editing its weights.
