Products and models

  • Business model

    Detail
    A shared model layer ("The Physical Intelligence Layer") that robot companies build on, connecting their own hardware to Pi's models[7]
    As of
    Feb 2026

  • Pi API

    Detail
    Pi API beta (Oct 13, 2026): upload robot data, launch fine-tuning on compute and infrastructure Pi manages, and run the fine-tuned model through a hosted inference gateway[6]
    As of
    Oct 2026

  • API access

    Detail
    Waitlist application; Pi is "starting small and onboarding in batches". The form asks about the team's robot-learning experience, robots available, hours of tele-op, UMI, egocentric and simulation data, and whether inference must run in the cloud, locally or both[9]
    As of
    Nov 2026

  • Pricing

    Detail
    None published: pi.website/pricing returns a 404 page, and neither the launch post nor the waitlist gives prices[10]
