# MetaRoboBench Pi05 Checkpoints

Offboarding archive of Pi05 inference checkpoints used in MetaRoboBench and RoboTwin2 experiments.

The most important available speed-control checkpoint is `checkpoints/pi05_ff500_chunk30/21650`. Its fixed-speed Clean results were Fast/Normal/Slow = 73.0/75.4/78.0 under 30 submitted actions, natural JAX policy noise, and inference metadata dropout disabled.

Each checkpoint preserves `params/`, `assets/`, and checkpoint metadata. Optimizer `train_state/` is intentionally excluded from the default archive.

The historical Quality-Mix checkpoint `10850` is not present. Only its configs and evaluation summaries survive; do not treat any other checkpoint as an exact copy of `10850`.
