π0 and π0-FAST: Vision-Language-Action Models for General Robot Control
Hugging Face Blog
Physical Intelligence's π0 and π0-FAST Vision-Language-Action models have been integrated into Hugging Face's LeRobot repository, enabling robots to perform complex manipulation tasks across different embodiments. π0 was trained on data from seven robotic platforms and 68 unique tasks, generating smooth action trajectories at 50Hz using flow matching. π0-FAST, an autoregressive variant using Frequency-space Action Sequence Tokenization, achieves 5x faster training than diffusion-based models while improving generalization across robot morphologies.
