π₀.₅ (Pi05 Libero) (LeRobot) π₀.₅ is a Vision Language Action (VLA) model with open world generalization from Physical Intelligence, co trained on robot demonstrations and large scale multimodal data to execute long horizon tasks in unseen real world environments. Checkpoint trained and evaluated on LIBERO tasks Note: This model currently supports only the flow matching action head for π₀.₅ training and inference. Other components from the original work (e.g., subtask prediction, action tokenization, or RL) were not released upstream and are not included here, though the LeRobot team is actively working to support them. Original paper: π0.5: A Vision Language Action Model with Open World Generalization Reference implementation: https://github.com/Physical Intelligence/openpi LeRobot implementation: Follows the original reference code for compatibility. Model description Inputs: images (multi view), proprio/state, optional language instruction Outputs: continuous actions Training objective: flow matching Action representation: continuous Intended use: Base model to fine tune on your specific use case Quick start (inference on a real batch) Installation For full installation details…
