pi0-base-for2wu

This repository contains the PI0 base PyTorch checkpoint used to train WendaYu/pi0-base-two-wu.

It was converted from the source PI0 base JAX checkpoint with the matching openpi-wu conversion code. This is the exact frozen backbone used for both stages of the two-Wu run:

VLM-Wu: 60,000 optimizer steps
Action-Wu: 85,000 optimizer steps in the published resumable checkpoint

The two-Wu training and inference code validates this fingerprint before loading Wu weights. A different base checkpoint is intentionally rejected.

The model configuration is PI0 (gemma_2b VLM plus gemma_300m action expert), action dimension 32, action horizon 50, and bfloat16 base-model precision.
