Study Reveals Multi-stage SFT Causes Task Conflicts, Favoring RL

A new study reveals that multi-stage Supervised Fine-Tuning (SFT) causes severe task conflicts and degrades reasoning abilities in LLMs. In contrast, Reinforcement Learning (RL) allows tasks to coexist peacefully, establishing it as a superior training paradigm.
