Full review →What is Chatbot Arena?
Chatbot Arena (LMSYS) is an open platform for evaluating and comparing large language models through blind side-by-side testing.

The Chatbot Arena leaderboard has become the de facto industry benchmark, frequently cited by AI labs, researchers, and journalists as the most reliable measure of model quality because it reflects real user preferences rather than synthetic benchmarks. The platform evaluates models across dimensions including overall quality, coding ability, reasoning, instruction following, and writing style. All data is open source, enabling academic research on human preferences in AI. The platform is completely free to use and is maintained by the LMSYS research group at UC Berkeley. It serves as an essential resource for anyone evaluating which AI model to use for specific tasks. The tool is best suited for anyone wanting to objectively compare ai model quality.
