MeanFlowNFT applies RL to MeanFlow generators

8/10

Researchers introduced MeanFlowNFT, a method that applies reinforcement learning (RL) to MeanFlow generators, which predict average velocities for efficient generation. MeanFlowNFT bridges the gap between MeanFlow and DiffusionNFT by constructing an induced instantaneous-velocity predictor, allowing for reward optimization. The method preserves MeanFlow's fast few-step generation and inherits DiffusionNFT's policy-improvement guarantee. Experiments on image and video generation show that MeanFlowNFT improves baselines and outperforms prior state-of-the-art RL-tuned generators. MeanFlowNFT achieves competitive results with fewer sampling steps, such as surpassing 50-step LongCat-Video RL with just 4 steps.
