HuggingChat
by Hugging Face
Open-source AI chat platform by Hugging Face with automatic model routing and access to a wide range of open models.
HuggingChat is Hugging Face's AI chat application for interacting with open and community-developed AI models. Its current experience uses Omni to automatically select an appropriate model for a user's request, while also allowing users to choose from available models directly. HuggingChat supports tasks such as coding, writing, research, reasoning, document and image-based workflows on supported models, and connects to Hugging Face Inference Providers. The platform is built around the open-source AI ecosystem and can work with many different models and providers through a single chat interface.
