Run, package, validate, or troubleshoot flex-pi inference and pinned public YAM training in NPA, including runtime-fetch assets, GPU workflows, and verified artifacts.
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
# flex-pi Run the genuine upstream 6B world-action checkpoint. Do not replace policy inference with an import check, random action fixture, or manifest-only smoke. ## Boundaries - Source: `geyan21/flex-pi@20c1b2b71ea35a415d5d47c39b04443cfadad7a1`, MIT, baked without the vendored simulators. - Checkpoint: `flex-pi/flexpi-robotwin@87d3833ea3bd89c4922945631db81b346e780785`, MIT-labelled, runtime fetch. - Observation: `flex-pi/robotwin_3d@bee164afe94041d8c3d7dd1203725c41163fc3f4`, episode 0 frame 0. Its dataset card declares no license. Use only under the operator's authorized scope, fetch at runtime, verify each byte hash, and do not publish the media. - DINOv3 uses its separate model license. The pinned converted Wan VAE/T5 and tokenizer repositories are Apache-2.0. They are operator runtime fetches; immutable revisions and heavyweight-file hashes are enforced before loading. - Before GPU allocation, run the HF credential preflight and the exact pinned DINOv3 weight HEAD probe in `docs/workbench/flex-pi.md#packaging-and-terms`. Flex-Pi is not in the generic health access catalog; an identity check or repository listing does not prove payload access. …

How to install
mdr add nebius/nebius-physical-ai/flex-pi@sha256:d5ace98bc1c6af05The line at the top of this page pins the label git:20261025.fb45527, 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.
