Hugging Face Chat UI

Overview

Hugging Face Chat UI is the open source codebase that powers HuggingChat: a fast, familiar chat interface for large language models. It gives a team one private front end for the model endpoint they already use, with conversations organised in a sidebar, model switching per conversation, image upload for multimodal models, replies that stream token by token, and one click data export.

Chat UI is a front end, not a model host. It calls any OpenAI compatible endpoint and discovers that endpoint's model list automatically, so it runs on a small CPU only machine with no GPU. Conversation history is kept in a MongoDB that ships alongside it and never leaves the instance.

Common uses

• A private team chat front end for the model provider you already pay for
• A self hosted interface for your own Ollama, vLLM or TGI endpoint
• Keeping chat transcripts inside your own subscription rather than a vendor's
