How this ranking is produced
- One metric, stated above — nothing here is weighted or scored by us. Scores come from LiveBench release 2026-06-25; models without a published run don't appear in score-based rankings.
- Price, context and capabilities — live from OpenRouter, refreshed every 15 minutes.
- Ties — scores less than a point apart are called a tie; effort settings alone move a LiveBench score by more than that.
A public benchmark is someone else's workload. Before committing, see LLM & agent evaluation.
