## Files

- `best.pt`: best validation checkpoint bundle
- `metrics.json`: per-epoch training and validation metrics

## Usage

These are NTILC checkpoint bundles, not plain `transformers` repositories. Load them with the local helper below.

```python
from training import load_checkpoint_bundle

bundle = load_checkpoint_bundle("best.pt", device="cpu")
print(bundle["architecture"], bundle["loss_name"], len(bundle["tool_names"]))
```

- `epochs`: `25`
- `best_epoch`: `23`
- `tool_count`: `26`
- `query_count`: `312`
- `best_val_retrieval_accuracy`: `0.8077`
- `best_val_classification_accuracy`: `0.7885`
- `silhouette_score`: `0.1559`
