Choose bigcode-evaluation-harness if…
- Tags unique to bigcode-evaluation-harness: python.
- Also covers Computer Vision.
- bigcode-evaluation-harness ships Docker support for self-hosted deployment.
When NOT to use bigcode-evaluation-harness
- Last GitHub push was 354 days ago (slowing maintenance, Jul 22, 2025). Validate activity before betting a new project on bigcode-evaluation-harness.
- 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.
Choose FastChat if…
- 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 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.
