DoubleFree method speeds up LLM training by reusing exploration data

Researchers have developed a new method called DoubleFree to improve the efficiency of training multi-task Large Language Models (LLMs). This technique reuses historical trajectories from domain-specific reinforcement learning, eliminating the need for costly online teacher responses during consolidation. By pre-computing teacher supervision, DoubleFree significantly speeds up the consolidation process and reduces computational resources required, while maintaining comparable performance across various domains like math, code, and instruction following.
