Black Forest Labs releases open-weights FLUX 3 Action SO-101 robot policy

Black Forest Labs has published FLUX 3 Action SO-101 on Hugging Face as an open-weights 7B world action model.

It takes two camera frames, the robot state, and a text instruction, then returns the next 42 actions with predicted video frames, with 32 executed at 30 Hz before replanning.

The card also provides a rank-32 LoRA fine-tuning recipe for user datasets and states that the application must enforce joint velocity, force, and workspace limits.
