Researchers have developed Subspace-Aligned Rewiring (SAR), a novel post-hoc editing method for large language models. SAR identifies and isolates the core reasoning components within reinforcement learning updates, which are often concentrated in the model's spectral space. By retaining these essential components and removing orthogonal, less effective parts, SAR can preserve over 99% of post-training performance while improving mathematical reasoning and agentic coding capabilities. This technique also facilitates model merging and purifies mixed-domain training, demonstrating its potential as a training-free mechanism to enhance LLM performance. AI
