BFL Open-Sources 7B FLUX 3 Action, Tops RoboLab Leaderboard
On September 24, Black Forest Labs (BFL) released FLUX 3 Action, an open-weight 7B world-action-model that ranked first on the RoboLab-120 leaderboard with less than half the parameters of the previous best open model. This marks the FLUX family's official expansion from image generation into embodied AI and robotics, and signals that world-action models are becoming a new battleground for top generative AI companies.
Confirmed
- FLUX 3 Action is a 7B open-weight world-action-model for robotics, built on the multimodal FLUX architecture and depending on LeRobot per its Hugging Face model page; product page at bfl.ai/models/flux-3-action, with the model collection on Hugging Face.
- Per BFL's official @bflai account and posts by @fruesome, @robrombach and @giffmana, the model topped the RoboLab leaderboard with 56% fewer parameters, 6.1 points above the prior best open model, and up to 3.95x faster inference.
- @StephanSturges noted SOTA performance and efficiency across multiple robotics leaderboards, with targeted improvements on the FLUX backbone.
- @DominiqueCAPaul highlighted that the 7B size runs on a single local RTX 5090 at roughly 180ms latency, making it practical for embodied applications.
- The FLUX 3 Action Base entry appeared on Hugging Face as early as September 22, with pipeline type robotics.
Why it matters
- It is a landmark move for BFL from image generation into embodied intelligence and robot control, showing world-action models becoming a new front for leading generative AI labs.
- Setting a new open-source SOTA with far fewer parameters and low-latency inference on a consumer GPU offers direct value to the ML community on deployment cost and efficiency.
