What you need
The server’s base URL (it usually ends in /v1) and, if it needs one, a key.
Set it up
- Open Settings ▸ Accounts and models and choose Custom (OpenAI-compatible)….
- Paste the server’s Base URL, for example
http://localhost:8080/v1. Add a key if the server needs one. - Press Verify. Infinity lists the server’s models; pick one and chat.
Good to know
- Jan, llama.cpp and GPT4All are found automatically when they’re running. In Jan, turn on Settings ▸ Local API Server.
- A server on your own Mac or network keeps your chats there. A cloud service gets what you send it, under its own terms.
