# Transformers MIC fleet

This dataset defines the Model Integration Contracts run by Transformers CI.

- `fleet-lock.json`: the control fleet, run with the default variant.
- `prototype-fleet.lock`: the prototype fleet, run with the bfloat16 variant.

Each entry pins a `huggingface-mic/<model>-mic` model snapshot containing the slim
weights, executable usage and reviewed Transformer expectations. Contract and
fixture hashes verify the pinned content. Known failures are scoped in the locks.

The runner lives in [transformers-ci](https://github.com/huggingface/transformers-ci).
Transformers pins the dataset commit SHA in `tests/contracts.lock`; CI uses
that revision for both fleet invocations. `tmic export --execute` updates this
dataset; `tmic pin --transformers-checkout PATH --revision SHA` adopts a revision.
Results and traces record that revision for reproduction. Model repository
revisions in the locks remain immutable even when this dataset is updated.

```bash
run-model-contracts --fixtures-only --fleet control
run-model-contracts --fixtures-only --fleet prototypes --variant bfloat16
# Reproduce a job with its recorded dataset commit:
run-model-contracts --fixtures-only --fleet prototypes --variant bfloat16 --fleet-revision <dataset-commit>
```

Update the locks after measuring and reviewing changed expectations. CI checks
against expectations; it does not record or approve new baselines.
