Use when connecting Antioch simulation to Workbench, configuring Antioch authentication, transferring recordings and checkpoints through Nebius S3, or operating the XR1 collection, fine-tuning, and evaluation pipeline.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Antioch and Workbench ## Integration contract Use the [XR1 cookbook](../../../docs/workbench/cookbooks/xr1-antioch.md) for the executable procedure and pinned inputs. The operator module at `npa/src/npa/workflows/xr1_antioch/operator.py` invokes the installed Antioch CLI from an operator-owned Antioch project. Its commands are `assets`, `runtime`, `source`, `collect`, `fetch`, `publish`, and `compare`. The `antioch` command wraps native CLI arguments; `exec` launches attached remote argv through the pinned SDK interpreter. Both resolve the NPA credential before launching. The training stage is the `workflow.xr1.finetune` toolRef in `workflows/partners/antioch/xr1-antioch-finetune.yaml`. It runs on Nebius and publishes checkpoints to S3. Antioch collection, transfers, and closed-loop evaluation are operator CLI/SDK steps around that YAML. Do not describe the entire loop as one submitted workflow. The separate `npa workbench antioch` commands operate the Workbench adapter and live OpenPI path; see the [partner catalog](../../../workflows/partners/antioch/README.md) to choose a flow. ## Authentication 1. Inspect the installed CLI/SDK version and run the cookbook's …

How to install
mdr add nebius/nebius-physical-ai/antioch-workbench@sha256:eff1c9903dd5d7f9The line at the top of this page pins the label git:20260923.3c7ccb6, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
