LLM Leaderboard

This LLM leaderboard displays the latest public benchmark performance for SOTA model versions released after April 2024. The data comes from model providers as well as independently run evaluations by Vellum or the open-source community. We feature results from non-saturated benchmarks, excluding outdated benchmarks (e.g. MMLU).
