Choose FastChat if…

  • FastChat is primarily Python; onepanel is Go.
  • Tags unique to FastChat: evaluation system, large-language-models, chatbots, distributed serving.
  • Also covers LLM Frameworks, Evaluation & Observability.
  • - 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 onepanel if…

  • onepanel is primarily Go; FastChat is Python.
  • Tags unique to onepanel: ai, aiops, annotation, deeplearning.
  • Also covers Vector Databases.
  • onepanel ships Docker support for self-hosted deployment.

When NOT to use onepanel

  • Last GitHub push was 1233 days ago (dormant maintenance, Feb 25, 2023). Validate activity before betting a new project on onepanel.
  • Vector Databases: Don't reach for a dedicated vector DB under ~100k vectors; pgvector on your existing Postgres is simpler to operate.
  • Model Training: Try prompting and RAG first; fine-tuning is the answer to style/format, not missing knowledge.
  • Inference & Serving: Self-hosting rarely beats a hosted API on cost until you have steady, high-volume traffic.
