zero2robot/policies

ONNX policies that drive the zero2robot course's live browser demos. Each file is the ONNX export of a from-scratch chapter policy; the site fetches these at build time (sha256-verified against checkpoints/models.yaml) and runs them in onnxruntime-web. No training required to read the course — these are the provisioned demo weights.
