Benchmark definition

LiveBench

ActiveEstablishedCommon useLIVEBENCH_FAMILY_REFERENCE

A rolling benchmark refreshed with objective, verifiable questions across six categories to reduce contamination and avoid LLM-as-judge scoring.

Applicability does not mean evaluated; benchmark result/model score data is outside this UI contract.

About

Description
LiveBench releases new questions and harder tasks over time. The maintained repository currently describes 18 tasks across six categories: math, reasoning, coding, data analysis, language, and instruction following.
What it measures
A broad, periodically refreshed set of objectively gradable LLM capabilities.
What it does not measure
A generic family record is not itself an immutable score-comparison target; exact release/version definitions are required for results.

Model requirements

Required conditions decide applicability. Relevant ones describe what the benchmark exercises and decide nothing.

This benchmark records no required conditions. Without requirements, no model can be shown to meet them, so every model is Not recorded. This is correct, not missing data.
