LiveBench
LiveBenchContamination-limited language-model benchmark with objective ground-truth answers and automatic scoring rather than judge models, spanning math, coding, reasoning, language, instruction following and data analysis. New questions are released monthly and older ones retired to limit contamination. Built by Abacus.AI with NYU, Nvidia, UMD and USC, and published as an ICLR 2025 spotlight.
Openness
5 high confidence- questions
- public
- answers
- public(ground_truth released)
- license
- Apache-2.0/MIT(repo LICENSE is Apache-2.0, carried over from FastChat
- datasheet
- present(docs/DATASHEET.md, a full datasheets-for-datasets questionnaire covering motivation, composition, collection and distribution)
- access
- ungated(HF datasets download without a gate)
All questions, answers, and code are released openly; rotation is for freshness, not access control. The documentation is a full datasheets-for-datasets questionnaire in the repository rather than a Hugging Face card, and it states the distribution license outright.

Adoption
3 medium confidenceAdoption is measured as Hugging Face downloads summed across LiveBench's ten per-domain dataset repositories, since the benchmark ships as a family of datasets rather than a single artifact. Most of the total comes from the six main task domains — math, reasoning, model judgment, coding, data analysis, instruction following and language — with three smaller companion sets contributing the rest.

Capability
not assessedA dataset is not 'capable' the way software or a model is, so capability is left unscored. LiveBench grades every question against objective ground truth rather than an LLM judge and rotates its six task domains monthly to resist contamination.
- https://arxiv.org/abs/2406.19314 recorded 2026-09-29
The arXiv abstract page for the LiveBench paper says "We release all questions, code, and model answers. Questions are added and updated on a monthly basis" and that top models score "below 70% accuracy". Searched the body for a capability score, SOTA and usage counts: none.
