LMArena.ai is an open-source platform developed by researchers at UC Berkeley SkyLab and LMSYS. It facilitates crowdsourced benchmarking of large language models (LLMs) through anonymous, head-to-head comparisons and user voting.
Users interact with two anonymized AI models by posing the same question to both. After reviewing the responses, users vote on which answer they prefer. This process helps in assessing the models based on human preferences.
WebDev Arena is a component of LMArena.ai where users can input web development tasks. The platform then generates code using different AI models, and users can compare the outputs to determine which model performs better in coding tasks.
Yes, LMArena.ai is free and open to the public. Users can participate in model evaluations, view leaderboards, and contribute to the benchmarking process without any cost.
Yes, LMArena.ai is accessible via web browsers on both desktop and mobile devices, allowing users to participate in evaluations from various platforms.
