Use when working on MolmoAct VLA fine-tuning/serving/evaluation workbench stages, MolmoAct policy configs, or the npa workbench molmoact CLI.
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
# MolmoAct MolmoAct is the vision-language-action tool for fine-tuning, serving, and evaluating MolmoAct VLA policies in npa. The three core stages (`finetune`, `serve`, `eval`) are currently stubs: they validate their arguments and return a plan-only manifest — actual trainer/server/evaluator execution is not wired up yet (tracking issue nebius/nebius-physical-ai#502). The base model (default `allenai/MolmoAct-7B-O-0812`) is resolved at runtime through the HF Hub cache via `npa.workbench.model_access` — weights are never bundled in the repo or image. ## Interfaces - CLI: `npa workbench molmoact <finetune|serve|eval> --help` - Python SDK: `npa.sdk.workbench.molmoact` (`finetune`, `serve`, `eval`) - Workflow module: `npa.workflows.byof.molmoact_pipeline` (argument validation, stub-manifest plumbing, argparse entrypoint) ## Conventions - The CLI lives at `npa.cli.workbench.molmoact` (multi-command package form for new tools); the SDK surface lives at `npa.sdk.workbench.molmoact`. - The `finetune` stage is the headline `molmoact/finetune` three-tier contract (CLI <-> SDK <-> `workflows/testing/molmoact-finetune.yaml`); …

How to install
mdr add nebius/nebius-physical-ai/molmoact@sha256:cd273eddaa1f38a9The line at the top of this page pins the label git:20260924.c2a1622, 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.
