License & attribution

Official HuggingFace dataset lmarena-ai/leaderboard-dataset, CC-BY-4.0, attributed to Arena (LMArena). The arena.ai site itself prohibits scraping — the HF dataset is the only ToS-clean channel.

What we ingest

Style-control leaderboard parquet: Arena score (Elo), CI bounds and vote counts per model, with per-category rows as separate benchmark versions. Elo is pool-relative — it never mixes with another source or averages with absolute metrics.

Snapshots are immutable raw payloads — every published number traces back to one. Re-fetching an identical payload bumps the re-fetch time instead of storing a duplicate. Scores from this source appear on benchmark profiles and model pages with this source linked.
