Flux 3 Action is a 7B open-weight diffusion transformer for robotic control that predicts future frames and actions jointly. Fine-tuned on DROID robot data, it achieves 42.92% success on RoboLab benchmark, outperforming larger models, with weights released under FLUX Kommunity License and code available on GitHub.
Black Forest Labs released FLUX 3 Action, a 7B model for robot action prediction that tops NVIDIA's RoboLab leaderboard at 42.9%, but its commercial license restricts use to companies with under $5 million annual revenue. The robotics research community continues advancing scaling laws and benchmarking approaches across multiple open-source and proprietary models.
