## OpenRouter benchmark datasets

- Publisher: OpenRouter

- Attribution: Source: OpenRouter (openrouter.ai), licensed under CC BY 4.0: reuse and republish with attribution to OpenRouter.
- Where: https://openrouter.ai/api/v1/datasets/exports/README.md
- Changes: Excluded auto-routing rows and rows whose runs covered on average fewer than 95% of the questions (total_questions / run_count); for each model version we use the rows of the model maker's own hosting if present, otherwise all providers, and publish the median row (the lower of the two middle rows when their number is even), so every value is one provider row's accuracy exactly as published (fractions 0–1).
