Researchers have developed a method to fix reasoning loops in the Qwen3.5-0.8B model by editing a small percentage of its weights. This modification significantly improved performance on the MATH-500 benchmark, increasing accuracy from 7.9% to 48.1%. The researchers used a 'Jacobian lens' to analyze the model's internal states, observing that the edit changed the model's decision-making process from doubt to verification at critical points. The modified model can be run locally and retains its improved performance even at lower quantization levels. AI
