> Each time I call the LLM api the fan starts to work and make big noise

So every time you do HTTP calls? Nothing there should spin up your fans, unless you use an agent with an horribly broken TUI, I've heard there is a few of those out there. But remotely calling LLM APIs really shouldn't be taxing on your local device, something somewhere is wrong/bad if that's what you're seeing.

Is it a local LLM? Sibling seems to be assuming remote, but I have trouble imagining a TUI that inefficient.
