BFL Releases FLUX 3 Action: Open-Weight 7B World Action Model Tops RoboLab

On September 24, Black Forest Labs (BFL) released FLUX 3 Action, an open-weight 7B world-action model, marking the FLUX series—best known for image generation—officially entering the embodied AI/robotics space. The model is available on Hugging Face, with the product page at bfl.ai/models/flux-3-action.

Confirmed

• FLUX 3 Action has 7B parameters with open weights, positioned as a world-action-model for robotics, built on the multimodal FLUX architecture and dependent on LeRobot (per the Hugging Face model page).
• It topped the RoboLab-120 leaderboard with less than half the parameters of the previous best open-source model, beating it by 6.1 percentage points while running up to 3x faster at inference.
• The model was released on Hugging Face as a collection, including entries such as FLUX 3 Action Base.

Why it matters

• This is a landmark move by BFL from image generation into embodied AI/robotics control, signaling that world-action models are becoming a new battleground for top generative AI companies.
• Setting a new open-source SOTA with significantly fewer parameters offers direct reference value for deployment cost and efficiency in the ML community.
