MMLU: Massive Multitask Language Understanding

Metric: Accuracy (higher is better)Introduced: 2021

Superseded by: mmlu-pro

About

Tests LLMs on undergraduate to professional level knowledge across 57 subjects with 15,908 multiple-choice questions. Top models now saturate at 86–90%; MMLU-Pro is the recommended harder successor.Compare model scores alongside pricing, API availability, and release date — high benchmark score alone doesn't make a model the right pick.

How to read this benchmark

This benchmark uses a scoring system where higher is better. Scores are useful for directional filtering and model shortlisting, not for universal quality ranking.

Interpretation checklist: prefer benchmarks that are closest to your workload style, then validate against the linked model pages for pricing, context window, and provider availability.

Trust when:

  • There is a fresh timestamped snapshot (or multiple snapshots) for this benchmark.
  • Model list covers the same version family you can actually deploy today.
  • Top candidates overlap with your required routing and feature requirements.

Don't trust when:

  • There is only one benchmark snapshot or the dataset appears stale.
  • Benchmark metric direction is opposite of your decision objective.
  • The score difference between options is narrow and likely within implementation variance.

Current modeled score band for tracked entries is roughly 92.4 – 88.7.
