SWEGraph v2 — Free Sample

A free, deterministic ~10% sample of SWEGraph v2: the complete SWE-bench family, SWE-smith and BigCodeBench normalized into proof chains (repo -> issue -> patch -> diff hunks -> tests -> agent task -> eval task) with identity/contamination groups and a leakage-audited split. The full package is sold separately (see below).

• License: CC BY-NC 4.0 for the MatrixNorm normalization/packaging layer (see Licensing).
• Format: gzipped CSV in csv/ (all columns as text; list fields pipe-delimited) plus a Parquet mirror in parquet/ with identical rows, used by load_dataset and the viewer.

from datasets import load_dataset
tasks = load_dataset("williamTLmiller/matrixnorm-swegraph-v2-sample", "agent_tasks", split="train")

How the sample was drawn

• Unit = repository family (a SWE-smith mirror belongs to its upstream's family). Keep a family iff the first byte of SHA-1("sample:" + family name) is < 26 (of 256). Families are kept whole, so contamination groups and partitions are never cut.
• Same rule on every table: tables with a repo_id keep the sampled families; group, quality, validity, proof, environment and membership rows are kept when they refer to a kept task or record. split_manifests is included in full.
• The split column is the full package's partition, unchanged. Because whole families are sampled, a sample may contain no validation or test family.

The full dataset

The licensed package holds every table above in full, plus per-entity JSONL streams with the complete nested fields (including each task's full PASS_TO_PASS regression list), provenance, rights and leak-audit files. Perpetual, non-exclusive license for internal research, training and benchmarking; models you train are yours to commercialize; no redistribution of the dataset itself.

Task content (issue text, patches, tests) comes from public open-source repositories and remains under each repository's own license; the exporter only ships verbatim code text where rights_manifest.csv allows it.

Licensing

• This sample: CC BY-NC 4.0 — attribution, non-commercial — applies to the MatrixNorm normalization and packaging layer.
• Underlying data: the source releases keep their own licenses (copies included as LICENSE-*-UNDERLYING-*.txt); repository content stays under each repository's license. See NOTICE.
• Commercial use of the normalized package requires the paid license.

Limitations

• Task validity gates are not_run until real execution evidence exists.
• Issue and PR text is reproduced from public GitHub as published in the source releases.
• Not produced, reviewed or endorsed by the authors of any source dataset.
