Why This Ranking?

Our rankings combine multiple authoritative sources: public benchmarks (SWE-bench, MATH, Arena), real-world user feedback, and our own systematic testing across different task scenarios.

We evaluate each model on task-specific criteria — not just general capability. A model that excels at coding may not be the best for creative writing, and vice versa.

Scores are updated monthly as new model versions are released. We also factor in pricing to help you find the best value, not just the highest raw performance.
