Analysis
This article from Practical AI discusses π0 (pi-zero), a general-purpose robotic foundation model developed by Sergey Levine and his team. The model architecture combines a vision language model (VLM) with a diffusion-based action expert. The article highlights the importance of pre-training and post-training with diverse real-world data for robust robot learning. It also touches upon data collection methods using human operators and teleoperation, the potential of synthetic data and reinforcement learning, and the introduction of the FAST tokenizer. The open-sourcing of π0 and future research directions are also mentioned.
