Starting with v0.2 of HuggingChat, users are authenticated through their HF user account.

By default, your conversations are shared with the model's authors (for the v0.2 model, to Open Assistant) to improve their training data and model over time. Model authors are the custodians of the data collected by their model, even if it's hosted on our platform.

If you disable data sharing in your settings, your conversations will not be used for any downstream usage (including for research or model training purposes), and they will only be stored to let you access past conversations. You can click on the Delete icon to delete any past conversation at any moment.

About available LLMs

The goal of this app is to showcase that it is now (May 2023) possible to build an open source alternative to ChatGPT. 💪

For now, it's running OpenAssistant's latest LLaMA based model (which is one of the current best open source chat models), but the plan in the longer-term is to expose all good-quality chat models from the Hub.

We are not affiliated with Open Assistant, but if you want to contribute to the training data for the next generation of open models, please consider contributing to ❤️

Technical details

This app is running in a Space, which entails that the code for this UI is publicly visible inside the Space repo.

Further development takes place on the huggingface/chat-ui GitHub repo.

The inference backend is running the optimized text-generation-inference on HuggingFace's Inference API infrastructure.

It is therefore possible to deploy a copy of this app to a Space and customize it (swap model, add some UI elements, or store user messages according to your own Terms and conditions)

We welcome any feedback on this app: please participate to the public discussion at

Coming soon

  • User setting to share conversations with model authors (done ✅)
  • LLM watermarking
