Research sources

See the sources behind every ranking and report.

Model Gauntlet aggregates established research sources and preserves the limits of each one. The current leaderboard is a single LMArena rating, not a consensus ranking. Historical ratings and model-release records remain separate.

OpenRouter routed-usage rankings

How we use it: Catalog metadata, republished with attribution
Coverage and update status: Checked on review. Publishes only the platform's own weekly routed token totals and request counts per listing variant. Usage volume is a popularity fact about one platform's routed traffic, never a quality benchmark. The endpoint is the public API behind the platform's rankings page, not part of the documented v1 API; schema drift fails the collector closed.
