Instead of ChatGPT

Conversational assistant with a hosted model.

The interface is easy: Open WebUI or LibreChat in an afternoon. The model is the hard part, and a 7B model on your GPU is not GPT-class.

You lose: The model quality, and the multimodality that comes with it.

The best interface here. It talks to any OpenAI-compatible endpoint, local or rented.

A compose file, a domain and a reverse proxy.

The runtime, not the chat app. You will want a front end.
