Physical Intelligence opens an API for robot-model fine-tuning and inference

pi.website 4 min read Editor score 7/10

The beta lets developers upload data, fine-tune robotic foundation models on managed compute and run them through a hosted inference gateway. It illustrates a hosted workflow for adapting robot models without building the full ML infrastructure in-house.

What
Pi API beta provides training and inference access to Physical Intelligence's robotic foundation models.
How
Developers upload data, fine-tune a π model on managed compute, then run it through hosted inference and use evaluation data to guide iteration.
Why it matters
Managed training infrastructure and a repeatable test-and-refine loop can ease the work of adapting models to robots.
fine-tune access inference test guide iteration your data π model hosted gateway robot evaluation data
The API workflow fine-tunes a model from uploaded data, runs it on a robot, and uses evaluation to guide iteration. Sketched from the article's own text.
