Choose huozi if…

  • Tags unique to huozi: fine-tuning, large-language-models, llm, nlp.
  • When working on projects that require fast integration of pre-trained language models through its streamlined fine-tuning capabilities.

Choose FastChat if…

  • Tags unique to FastChat: chatbot arena, llm-evaluation, multi-model serving, openai-compatible apis.
  • Also covers Evaluation & Observability, Inference & Serving.
  • When you need a platform that supports both training and evaluation of large language models, such as Vicuna, and you want to leverage human feedback for model evaluation.

When NOT to use FastChat

  • If you are looking for a platform that focuses solely on model training without serving or evaluation capabilities, FastChat offers a comprehensive suite that might be more than you need.
  • If your project does not require human feedback for model evaluation, FastChat's integration with Chatbot Arena might be an unnecessary feature.
  • If you are working with proprietary or closed-source models, FastChat's open-source nature and reliance on open-source models like Vicuna might not align with your project requirements.
