# Chatbot Arena Chatbot Arena is an LLM benchmark platform featuring anonymous, randomized battles, available at https://arena.lmsys.org. We invite the entire community to join this benchmarking effort by contributing your votes and models. ## How to add a new model If you want to see a specific model in the arena, you can follow the steps below. 1. Contribute code to support this model in FastChat by submitting a pull request. See [instructions](model_support.md#how-to-support-a-new-model). 2. After the model is supported, we will try to schedule some computing resources to host the model in the arena. However, due to the limited resources we have, we may not be able to serve every model. We will select the models based on popularity, quality, diversity, and other factors.
