Data Sources & Licenses
Every upstream dataset this site reads from, all under open licenses. We publish no data of our own — prices are the higher-confidence reading of models.dev / LiteLLM (conflicts flagged on the model page), benchmark rows are mapped to our model entries by name, and reasoning-effort variants are merged per model with only the canonical row shown.

LiveBench (detail pages only)
LiveBench scores appear only on a model's own pricing page, in a separate section, and never in any leaderboard, table, comparison list or JSON-LD structured data on this site. License is CC BY-SA 4.0; the source repository itself does not carry a LICENSE file but livebench.ai's own footer states CC BY-SA 4.0, so we follow that and restrict use to attributed, on-page display only.
