err2fix-py-v1 is intended for retrieval workflows that map Python error strings or troubleshooting queries to the most relevant fix snippets, docs excerpts, or known solutions.
This model is retrieval-only. It is not a generator, reranker, multilingual model, or production-serving package.
Training Data
Local curated dataset: 468 manually reviewed examples
The model performs strongly on the curated Python troubleshooting evaluation split, but broad-domain retrieval transfer is limited. Published MTEB metadata currently reflects the available official-style retrieval task results in the model card metadata.
Future updates should be selected using both the Python troubleshooting split and a broader English Retrieval validation slice.
Reproducibility
Setup and validation:
bash
1uv sync --group dev
2uv run --group dev pytest
3uv run --group dev ruff check .4uv run --group dev mypy src
5uv build
Baseline evaluation:
uv run python scripts/evaluate_baseline.py
Tuned checkpoint evaluation:
uv run python scripts/evaluate_checkpoint.py --model training/runs/20260420T091003Z/model --source submission-candidate-v1.1 --output evaluation/runs/err2fix-py-v1-phase11-sweep-b-margin03-on-468.json
Limitations
Local Python troubleshooting evaluation currently saturates for tuned checkpoints on the 468-example snapshot.
Performance claims are scoped to the repository dataset and domain slice, not broad MTEB generalization.
This model is not intended for JavaScript troubleshooting, multilingual retrieval, reranking, or generation.
Ethical and Safety Notes
This model assists troubleshooting retrieval and can return incomplete or context-specific fixes.
Retrieved guidance should be validated against environment specifics (OS, Python version, dependency set) before application.
