Choose FastChat if…
- License: FastChat is Apache-2.0, fastDeploy is MIT.
- Tags unique to FastChat: chatbots, distributed-serving, evaluation system, large-language-models.
- Also covers Evaluation & Observability, LLM Frameworks.
- - You are looking to train and evaluate state-of-the-art models such as Vicuna or MT-Bench.
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.
Choose fastDeploy if…
- License: fastDeploy is MIT, FastChat is Apache-2.0.
- Tags unique to fastDeploy: deep-learning, docker, falcon, gevent.
- Also covers Speech & Audio.
When NOT to use fastDeploy
- Last GitHub push was 154 days ago (slowing maintenance, Feb 10, 2026). Validate activity before betting a new project on fastDeploy.
- Inference & Serving: Self-hosting rarely beats a hosted API on cost until you have steady, high-volume traffic.
- Model Training: Try prompting and RAG first; fine-tuning is the answer to style/format, not missing knowledge.
