>> No, I haven’t tried that yet. I don’t really want to turn on auto mode when it’s iterating on my credit card and it looks like it’s in an infinite loop… Is that a silly thing to be worried about?

Yeah. Most AIs today are pretty good at detecting that they're in a loop and aren't making progress. When that happens, they either take a different approach, or stop and say they are stuck. But, if you're really worried about it, you can cap monthly spend on the billing page of virtually every AI provider.
