Choose huozi if…
- Tags unique to huozi: fine-tuning, llm, nlp.
- When working on projects that require fast integration of pre-trained language models through its streamlined fine-tuning capabilities.
- Leaner open-issue backlog (0).
When NOT to use huozi
- If your project requires proprietary licensing, as Huozi is under the Apache-2.0 license which may not meet all business models' requirements.
- When needing a framework with comprehensive support for visual data or other non-textual machine learning applications.
Choose FastChat if…
- Tags unique to FastChat: chatbots, distributed-serving, evaluation system.
- Also covers Evaluation & Observability, Inference & Serving.
- - 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.
