Has anyone already implemented a GPT-like service payable with #Bitcoin Lightning? I think of a VPS with Ollama as backend and to use it you have to pay some sats per-request or per-month. Imagine having the frontend chat inside a #Nostr app and being able to pay and use it with just a Zap. You can view a list of public servers and choose the one you want to use based on the price they ask or other properties. So there could be a market of them. Inside an app like @primal, which already has builtin Lightning wallet capabilities, it would also eliminate the need for the user to have an external wallet, reducing friction even more.
