# LMArena

Canonical: https://www.softwareadvice.ie/software/631319/LMArena

> LMArena is a platform for evaluating and benchmarking AI models using human preference-based voting. It is designed for AI researchers, developers, model creators, and organizations seeking transparent insights into AI model performance across various capabilities. Since March 2024, the platform has supported testing of proprietary and open-source models from major laboratories and independent teams, including pre-release versions that benefit from community feedback.

The platform features an anonymous battle mode where users submit prompts and receive responses from two unidentified AI models. Users evaluate these responses and vote for their preferred option. Feedback contributes to public leaderboards and is shared with model developers to support improvements. The system evaluates multiple AI capabilities, such as chat, text generation, image generation, video generation, web development, document processing, and search functionality. After voting, the platform reveals model identities and allows users to continue conversations or start new comparisons. Leaderboard rankings are maintained across categories such as Overall, Agent, Alignment Index, Text, Web Development, Vision, and Search.

LMArena has open-sourced a large repository of human preferences on generative models, with datasets available on HuggingFace. The platform has published research papers at conferences such as ICML, NeurIPS, and ICLR, covering topics including prompt-to-leaderboard analysis, adversarial attack mitigation, and benchmarking methodologies. It operates under defined privacy and transparency policies to ensure ethical data handling and community trust.
