- 2 neurons. - columns in layer 29. - 0.00012% of weights. - Math score almost doubled. Claude Opus 5.5 just performed targeted weight surgery on Qwen3.5-4B and boost performance. It identified the exact neurons causing reasoning loops and removed that direction editing only 0.00012% of the model. results: - Math accuracy: 59 to 92-94 up - Repetition loops: 22–25 to 0. - Zero human intervention. - No gradients, No training loop, Just 2 neuron columns edited by Opus 5.5 in 27 minutes for $1.03. https://x.com/zengjiajun_eth/status/2117409198686216574/photo/1
