Overview

HuggingChat is Hugging Face's free, open-source chat interface for talking to leading open-weight models like Llama, Qwen, and Mistral without paying for API access or building your own front end. It supports image generation, web search, MCP tool calling, and multimodal image uploads, giving anyone a no-cost way to try the models research labs are actually shipping instead of being locked into one closed provider.
