The LMSYS Chatbot Arena is a platform for evaluating large language models (LLMs) through live, community-driven evaluations. Users engage in conversations with anonymized AI models and vote on which performs better in pairwise comparisons. It has evaluated over 90 LLMs, including commercial and open-source models, and provides regular updates and insights into model performance trends. The Chatbot Arena emphasizes real-world, dynamic evaluation, complementing static benchmarks like the Open LLM Leaderboard.
Hugging Face has upgraded the Open LLM Leaderboard by introducing more complex evaluation metrics and providing detailed analyses to help users understand which tests are most relevant for specific applications. The revamped leaderboard includes more challenging datasets, multi-turn dialogue evaluations, expanded non-English language evaluations, and tests for instruction-following and few-shot learning.
The Open LLM Leaderboard and Chatbot Arena differ in their approach to evaluating AI models. The Open LLM Leaderboard focuses on static benchmarks and structured tasks, while the Chatbot Arena emphasizes real-world, dynamic evaluation through direct user interactions. The Leaderboard provides a more controlled environment for testing specific capabilities, while the Chatbot Arena offers continuous, diverse, and real-world testing scenarios.
