FastChat
FastChat — An open-source platform for training, serving, and evaluating large language model-based chatbots.
Overview
FastChat is an open-source platform designed for training, serving, and evaluating large language model-based chatbots. It powers Chatbot Arena, which serves over 10 million chat requests for 70+ LLMs and has collected over 1.5M human votes from side-by-side LLM battles to compile an online LLM Elo leaderboard. FastChat offers training and evaluation code for state-of-the-art models, a distributed multi-model serving system with a web UI, and OpenAI-compatible RESTful APIs.
Key Features
- Training and evaluation code for state-of-the-art models like Vicuna and MT-Bench.
- Distributed multi-model serving system with a web UI and OpenAI-compatible RESTful APIs.
- Supports large-scale real-world LLM conversation datasets and human preferences.
Use Cases
- Researchers and developers can use FastChat to train and evaluate their own large language models.
- Companies can leverage FastChat to serve and manage multiple chatbot models through a single platform.
- The platform can be used to collect and analyze human votes and preferences for chatbot performance comparison.
Advantages
- Open-source and community-driven, allowing for continuous improvement and adaptation.
- Supports a wide range of large language models, making it versatile for different applications.
- Provides a leaderboard for comparing the performance of different chatbots, fostering innovation and competition.
Limitations / Considerations
- The platform's performance may be affected by the complexity and size of the language models it serves.
- Requires a certain level of technical expertise to set up and manage effectively.
- The open nature of the platform may pose challenges in maintaining consistency and quality across different models.
