It powers ChatB ## Choose when ### Choose IntelliServer if… - IntelliServer is primarily JavaScript; FastChat is Python. - License: IntelliServer is MIT, FastChat is Apache-2.0. - Tags unique to IntelliServer: image-generation, gpt4, ai, docker. - Also covers Computer Vision. ### Choose FastChat if… - FastChat is primarily Python; IntelliServer is JavaScript. - License: FastChat is Apache-2.0, IntelliServer is MIT. - Tags unique to FastChat: evaluation system, large-language-models, chatbots, distributed serving. - Also covers Model Training, Inference & Serving. - - You are looking to train and evaluate state-of-the-art models such as Vicuna or MT-Bench. ## When NOT to use IntelliServer - Last GitHub push was 489 days ago (dormant maintenance, Mar 10, 2025). Validate activity before betting a new project on IntelliServer. - LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves. - Evaluation & Observability: Defer heavyweight eval infra only until you have real traffic - never skip it once users depend on answers. ## When NOT to use FastChat - - You require a proprietary or closed-source framework; FastChat is open-source under Apache-2.0 license and its use might be unsuitable for environments requiring proprietary solutions. - - Your chatbot evaluation needs do not align with the types of data used in FastChat's datasets (e.g., human votes, MT-Bench evaluations). - - You prefer a more user-friendly setup without the need to clone a repository and manually install dependencies; FastChat requires installation from source with additional steps for Rust and CMake on - + Mac. ## Common questions ### What is the difference between IntelliServer and FastChat?
