# Hugging Face Specialist Model Archive v1

This archive makes artifact storage explicit: unique posttrainllm model outputs live on Hugging Face, while plain upstream base-model caches are removed locally instead of being mirrored under posttrainllm.

- Hugging Face
- artifacts
- specialists
- cleanup

## Headline Numbers

Evidence class applies to each value: measured = retained evaluation or runtime result; historical = recorded result not freshly reproduced; derived = calculated or decided from records; observed = current artifact state; not-measured = an explicit evidence gap.

posttrainllm HF repos

 6 all have first-class case studies observed

Local model cache

 cleared after upload/remote-size verification observed

Storage policy

 HF first R2 remains optional private cache or legacy mirror derived

 [Hugging Face artifact storage](https://huggingface.co/posttrainllm) public model distribution active model repos Direct Current target for public weights, adapters, and large specialist artifacts.

 Local Mac cache durable artifact storage rejected ~30GB cleaned Direct Useful during training, but not the system of record after a model is uploaded or known re-downloadable.

 Cloudflare R2 artifact storage role optional private cache / legacy mirror Directional No longer the default public artifact store for model weights.

Direct rows share this artifact's eval setup. Directional rows are useful market context but should not be read as leaderboard claims.

## Release Blockers

### Archive entries are not ship decisions

Public weights can be useful as evidence without being the selected model for Pace or any product lane.

 Unblock: Promote only candidates with a current factory run, eval report, package metadata, and routed-use decision.

### VibeThinker distilled eval needs promotion

The weights are preserved, but the public artifact should not imply a measured win until the eval evidence is attached.

 Unblock: Run the factory eval gate and publish a before/after report before using it as a specialist package.
