Black Forest Labs Releases FLUX 3 Action: A 7B Open-Weights World Action Model That Tops RoboLab-120

Black Forest Labs released FLUX 3 Action, a 7 billion parameter open-weights model designed to control robots by reading camera frames and text instructions, then predicting future video frames and robot actions together. The model ranks first on the RoboLab-120 benchmark at 42.92% task success, outperforming larger competing models while running 1.5 to nearly 4 times faster. This matters because it addresses a tradeoff in robot control systems: models that predict video tend to be accurate but slow, while faster models sacrifice accuracy. The model can be deployed on consumer and professional GPUs with quantization techniques and is available under a non-commercial license with code and documentation for fine-tuning on custom robot demonstrations.
