FastChat (Local)

FastChat is an open-source platform developed by LMSYS Org (Large Model Systems Organization) used for training, serving, and evaluating large language model-based chatbots. It provides the necessary infrastructure to host multiple conversational AI models locally or on the web. The platform is heavily utilized by researchers looking to benchmark and test their custom models.

Yes, FastChat is the underlying software framework that powers the popular LMSYS Chatbot Arena. The Chatbot Arena is a crowdsourced evaluation platform where users converse with two anonymous models side-by-side and vote on which response is better. FastChat handles the web serving, API routing, and data collection for this large-scale benchmark.

Yes, FastChat is designed to be highly flexible and can be deployed locally on your own hardware, provided you have sufficient computational resources. You can use the FastChat CLI (Command Line Interface) to serve open-source models like Vicuna or LLaMA on local GPUs. This allows developers to test models privately without relying on external cloud APIs.

Yes, FastChat includes features for distributed serving, allowing you to balance the workload of large language models across multiple GPUs or even multiple machines. It uses a controller-worker architecture to manage API requests efficiently. This makes it highly scalable for enterprise applications or research labs running heavy concurrent inference loads.
