Rethinking Generalization in Reasoning SFT: A Conditional Analysis on Optimization, Data, and Model Capability

Researchers challenge the conventional wisdom that supervised finetuning (SFT) merely memorizes while reinforcement learning generalizes. Their analysis reveals that reasoning SFT with chain-of-thought supervision can generalize across domains, but success depends critically on optimization duration, data quality, and base model strength, with generalization improvements coming at the cost of degraded safety performance.

It's Not the Capability: Harness Sensitivity Is Non-Monotone Across LLM Agent Tiers

A controlled study of 432 experiments across six LLM models challenges the assumption that higher-capability models require less structural guidance. The research reveals non-monotone harness sensitivity patterns, where frontier models like Gemini 2.5 Flash show performance degradation with increased harness complexity, while reasoning-focused models benefit from stricter constraints.

Counteraction-Aware Multi-Teacher On-Policy Distillation for General Capability Recovery with Domain Preservation

Researchers propose CaMOPD, an improved machine learning method that helps large language models recover general capabilities after being fine-tuned for specific domains. The approach addresses a key technical challenge where mixing recovery and preservation training signals creates conflicting gradients, achieving better performance than existing multi-teacher distillation methods.
