Detailed Description

LMArena is a public, web‑based AI benchmarking arena created by UC Berkeley researchers, where users submit prompts and compare anonymous chatbot responses in head‑to‑head battles then share votes that reveal human‑rated AI performance. With over a million votes cast and backing from major models like GPT‑4o, Gemini and Claude, it offers transparent, user‑driven insights into state‑of‑the‑art model capabilities while continuously evolving its methodology to address sampling biases and ensure fairness.
