# FastChat ## Docs - [FastChat](https://fastchat.mintlify.app/introduction.md): FastChat is an open platform for training, serving, and evaluating large language model based chatbots - [Install](https://fastchat.mintlify.app/install.md) - [API](https://fastchat.mintlify.app/api-reference.md) - [Chatbot Arena](https://fastchat.mintlify.app/arena.md): Chatbot Arena is an LLM benchmark platform featuring anonymous, randomized battles, available at https://chat.lmsys.org. We invite the entire community to join this benchmarking effort by contributing your votes and models. - [AWQ 4bit Inference](https://fastchat.mintlify.app/awq.md): We integrated [AWQ](https://github.com/mit-han-lab/llm-awq) into FastChat to provide **efficient and accurate** 4bit LLM inference. - [GPTQ 4bit Inference](https://fastchat.mintlify.app/gptq.md): Support GPTQ 4bit inference with [GPTQ-for-LLaMa](https://github.com/qwopqwop200/GPTQ-for-LLaMa). - [Local LangChain with FastChat](https://fastchat.mintlify.app/langchain_integration.md): [LangChain](https://python.langchain.com/en/latest/index.html) is a library that facilitates the development of applications by leveraging large language models (LLMs) and enabling their composition with other sources of computation or knowledge. FastChat's OpenAI-compatible [API server](openai_api)… - [Model Support](https://fastchat.mintlify.app/model_support.md) - [FastChat Server Architecture](https://fastchat.mintlify.app/server_arch.md) - [Fine-tuning FastChat-T5](https://fastchat.mintlify.app/training.md): You can use the following command to train FastChat-T5 with 4 x A100 (40GB). - [Vicuna Weights](https://fastchat.mintlify.app/vicuna_weights_version.md) - [vLLM Integration](https://fastchat.mintlify.app/vllm_integration.md): You can use [vLLM](https://vllm.ai/) as an optimized worker implementation in FastChat. It offers advanced continuous batching and a much higher (~10x) throughput. See the supported models [here](https://vllm.readthedocs.io/en/latest/models/supported_models.html). ## Optional - [Discord](https://discord.gg/HSWAKCrnFx) - [Demo](https://chat.lmsys.org/)
