New! Check out LiveSWEBench, our new benchmark for AI coding agents

Introduction

Introducing LiveBench: a benchmark for LLMs designed with test set contamination and objective evaluation in mind. It has the following properties:

  • LiveBench limits potential contamination by releasing new questions regularly.
  • Each question has verifiable, objective ground-truth answers, eliminating the need for an LLM judge.
  • LiveBench currently contains a set of 18 diverse tasks across 6 categories, and we will release new, harder tasks over time.

We will evaluate your model on LiveBench! Open a github issue or email us at livebench.ai@gmail.com!

We update questions regularly so that the benchmark completely refreshes every 6 months. All questions for previous releases are available here. The most recent version is LiveBench-2025-04-02. This verison includes updated coding, language, math, and reasoning questions.
To further reduce contamination, we delay publicly releasing the questions from the most-recent update. LiveBench-2025-04-02 had ~300 new questions, so currently ~30% of questions in LiveBench are not publicly released.
