Black Forest Labs releases FLUX 3 Action base weights for robot adaptation
Original titleblack-forest-labs/flux-3-action-base
Black Forest Labs has released flux-3-action-base, an open-weights 7B world action model that takes camera frames, robot state, and a text instruction to output the next action chunk.
The release is an adaptation component rather than a complete robot policy, and new embodiments require their own action heads.
The source says the weights are paired with shared video VAE and Qwen3-VL-4B-Instruct text encoders and is governed by the FLUX Kommunity License v.1.0.
The source separates the adaptation base from full robot policies and states the shared encoders and new-embodiment requirements, which clarifies what developers must still build for their robots.
