FAQPage Schema
How do I fine-tune OpenPI models for robot policy inference?

To fine-tune OpenPI models, you prepare custom datasets for environments like ALOHA, DROID, or LIBERO, run deterministic training steps, convert checkpoints, and deploy via WebSocket policy serving for real-time robot inference.

Can I use JAX and PyTorch backends for OpenPI fine-tuning?

Yes, OpenPI fine-tuning supports both JAX and PyTorch backends, allowing you to train and serve robot policies across multi-env deployments using either on-disk or remote checkpoints.

What is the best way to serve OpenPI policies on robots?

The best way to serve OpenPI policies is through WebSocket policy serving, which enables real-time inference for deployed robots or simulators after converting your fine-tuned checkpoints.

Does OpenPI fine-tuning work with ALOHA, DROID, and LIBERO environments?

Yes, OpenPI fine-tuning explicitly supports ALOHA, DROID, and LIBERO environments, enabling you to adapt pi0, pi0-fast, and pi0.5 models to custom datasets across these robotics platforms.

Why does OpenPI fine-tuning require deterministic training steps and norm stats?

Deterministic training steps and norm stats ensure consistent, reproducible model adaptation when fine-tuning OpenPI policies, preventing variance in robot behavior during real-time inference deployment.

Do I need checkpoint conversion before deploying OpenPI models?

Yes, checkpoint conversion is required to transform fine-tuned OpenPI models into a deployable format, enabling real-time WebSocket policy serving on robots or simulators.
