We are thrilled to launch the 2025 WSDM Cup: LMSYS Multilingual Chatbot Arena Prediction Contest, in collaboration with Kaggle and LMSYS.org. This year's challenge focuses on creating multilingual auto-rater models using chatbot arena data. In order to provide a strong ability to ensure that these models are indeed reflective of human evaluations, we have worked in partnership with LMSYS.org <http://lmsys.org/>, which has become one of the leading resources for the field through their well known chatbot arena lmarena.ai <http://lmarena.ai/>. This arena has led the way in open-ended, community based evaluations of LLMs in blind side-by-side comparison, and provides the perfect resource for training and evaluating auto-rater models. Hosted by Kaggle, with a prize fund of $50,000 USD, the competition begins Monday, November 18, 2024, and submissions close February 3, 2025.
