I would recommend instead to use the AI Horde: https://stablehorde.net/ It’s a collection of people hosting stable diffusion/text generation models
There’s also openrouter which can connect to ChatGPT with a token-based system. (They check your prompts for hornyposting though)
The best self hosted alt I’ve seen is huginn: https://github.com/huginn/huginn
It’s not as easy to use as ifttt and much less already built for you but it does the same things.
I’d say mostly energy savings and CPU usage efficiency
