MIT's GPT-6 Astra performs 'brain surgery' on Qwen AI, boosting math scores

By PulseAugur Editorial · [6 sources] ·

Researchers from MIT have demonstrated a novel method where one AI, GPT-6 Astra, directly edited the weights of another AI, Qwen, without traditional training. This process, likened to gene editing for neural networks, involved modifying a small fraction (0.016%) of Qwen's weights. The intervention significantly boosted Qwen's performance on the MATH-500 benchmark, increasing its score from 7.9% to 48.1%. However, the researchers noted that this technique was effective only in removing a performance bottleneck rather than imparting new skills. AI

IMPACT Demonstrates a potential new paradigm for AI model improvement by directly editing weights, bypassing traditional training cycles.
