# SWE-rebench-V2 clean Python tasks

A train/test split of Python tasks from [nebius/SWE-rebench-V2](https://huggingface.co/datasets/nebius/SWE-rebench-V2).
We took the Python subset of the original dataset and kept only the tasks where the golden patch passes
the unit tests and the empty patch does not.

- **train**: 3,837 instances from 408 repositories
- **test**: 500 instances from 100 repositories

The split is made by repository, so no repository appears in both splits.

We evaluated multiple models on the test split as of June 2026 — the comparison is
