HuggingChat

HuggingChat is Hugging Face's free AI chatbot interface that provides access to the latest open-source language models including Llama, Mistral, and others. It offers a ChatGPT-like experience powered entirely by open models, with no subscription required. The platform lets users switch between different open models to compare their capabilities. It includes web search integration for grounded answers, file upload for document analysis, and the ability to create custom assistants with specific instructions. HuggingChat serves as both a practical AI assistant and a showcase for the open-source AI ecosystem. It is particularly valuable for users who want capable AI chat without sending data to proprietary providers, and for developers evaluating which open model best fits their needs.
