New GFT framework unifies SFT and RL for more stable LLM training

By PulseAugur Editorial · [1 sources] ·

Researchers have introduced Group Fine-Tuning (GFT), a novel framework designed to unify supervised fine-tuning (SFT) and reinforcement learning (RL) for large language models. GFT addresses limitations in traditional SFT, such as single-path dependency and unstable weighting, by employing Group Advantage Learning and Dynamic Coefficient Rectification. Experiments indicate that GFT outperforms standard SFT methods and facilitates smoother integration with subsequent RL training. AI

IMPACT Introduces a unified training framework that may improve LLM generalization and RL integration.

    GFT: From Imitation to Reward Fine-Tuning with Unbiased Group Advantages and Dynamic Coefficient Rectification

    arXiv:2604.14258v2 Announce Type: replace-cross Abstract: Large language models are typically post-trained using supervised fine-tuning (SFT) and reinforcement learning (RL), yet effectively unifying efficient knowledge injection with robust generalization remains challenging. In…
