Physical Intelligence, the San Francisco-based startup that has raised more than $400 million, has open-sourced its Pi0 robotic foundation model. Pi0 was introduced a few months ago and can be tuned to a range of tasks, including folding laundry, cleaning a table, scooping coffee beans, and more. Physical Intelligence has released the code and weights for Pi0 as part of its experimental openpi repository on GitHub. It also provides checkpoints for a few “simple tasks” on available platforms such as ALOHA and DROID, example code to run inference on real-world and simulated robot platforms, and the code for fine-tuning the base π0 model for your own tasks and platforms. The company said between 1-20 hours of data was sufficient to tune Pi0 to a variety of tasks in its own experiments. HuggingFace has also prepared a PyTorch port of openpi for those developers who prefer PyTorch over JAX

Hugging Face and Physical Intelligence have quietly launched Pi0 (Pi-Zero) this week, the first foundational model for robots that translates natural language commands directly into physical actions.“Pi0 is the most advanced vision language action model,” Remi Cadene, a principal research scientist at Hugging Face, announced in an X post that quickly gained attention across the AI community. “It takes natural language commands as input and directly outputs autonomous behavior.”This release marks a pivotal moment in robotics: The first time a foundation model for robots has been made widely available through an open-source platform. Much like ChatGPT revolutionized text generation, Pi0 aims to transform how robots learn and execute tasks. How Pi0 brings ChatGPT-style learning to robotics, unlocking complex tasksThe model, originally developed by Physical Intelligence and now ported to Hugging Face’s LeRobot platform, can perform complex tasks like folding laundry, bussing tables and packing groceries — activities that have traditionally been extremely challenging for robots to master.“Today’s robots are narrow specialists, programmed for repetitive motions in choreographed settings,” the Physical Intelligence research team wrote in their announcement post
