Black Forest Labs releases FLUX 3 Action, an open robotics model
Black Forest Labs has launched FLUX 3 Action, an open AI model specifically designed for robotics applications. Building on the multimodal FLUX 3 foundation, which was trained on video, image, and audio data, this new model functions as a world-action model. It processes multi-camera video feeds from a robot's workspace to predict the next action an agent should take and how the environment will…
Key points
- FLUX 3 Action uses seven billion parameters, less than half the size of the previous best open model.
- The model runs up to 3.95 times faster than the previous best open model on the RoboLab-120 leaderboard.
- Weights are available on Hugging Face, allowing for on-device deployment and digital environment testing.
According to Black Forest Labs, FLUX 3 Action achieves a record success rate on the RoboLab-120 leaderboard. The model uses only seven billion parameters, making it less than half the size of the previous best open model. It also runs up to 3.95 times faster than its predecessor. The company argues that while large reasoning models can plan effectively, they are often too slow and bulky for real-time robot deployment, making this efficiency critical for on-device use.
Beyond physical robotics, Black Forest Labs sees potential for the model in digital environments. Video games could serve as testing grounds for navigation and fast-reacting agents that might eventually operate computers. The model weights are available for download on Hugging Face.
