DiffusionNFT

DiffusionART, a new reinforcement-learning fine-tuning method for diffusion models from the arXiv paper 2610.12572v1, reaches the late-stage mean reward levels of DiffusionNFT and Flow-GRPO-Fast on Hu…

Researchers propose reward-based velocity matching (RVM), a trajectory-free update for fine-tuning diffusion models that acts directly on the velocity field, eliminating the need for likelihood-based …
