Black Forest Labs ships FLUX 3 Action, an open-weights 7B world-action model for robot control
Black Forest Labs
BFL released FLUX 3 Action, a 7B open-weight World Action Model that jointly predicts future video frames and robot actions from camera frames, robot state and text. BFL claims 42.92% on the RoboLab-120 benchmark, above NVIDIA's 16B Cosmos 3 Nano (36.8%) and Physical Intelligence's pi-0.5 (28%), with distilled variants running up to ~4x faster in FP8; third-party Franka-arm eval showed 28/30 successes. Weights (base, guidance-distilled, step-distilled), the training recipe and LeRobot/Jetson integration are public.
Why it matters
First open-weights leaderboard-topping robotics world model at under half the size of NVIDIA's competing Cosmos 3, extending the FLUX 3 video-gen backbone into real robot control.
