HuggingChat is Hugging Face's free, open-source chat interface offering access to over 120 open-weight models including Llama, Mistral, Qwen, DeepSeek, and Falcon, with a new Omni routing layer that automatically picks the most suitable model for a request. It is aimed at developers, ML researchers, and technically curious users who want to compare model outputs or avoid handing data to a closed-source provider, though it also works for general use cases like writing, coding help, document analysis, and Q&A. The platform is completely free to use, with a Hugging Face Pro subscription at $9/month, and API pricing via the Hugging Face Inference API starting from $0.03/hour for CPU instances. Its distinguishing functions include multi-model switching, Omni routing, web search, custom Assistants, and document upload, but it has a bare-bones interface, no dedicated mobile app, and speed dips under load.
