I saw this on reddit, thinking it’s a joke, but it’s not. GPT 5 mini (and maybe sometimes 5) gives this answer. You can check it yourself, or see somebody else’s similar conversation here: https://chatgpt.com/share/689a4f6f-18a4-8013-bc2e-84d11c763a99
Personally, as someone who prefers it when software only does things I direct it to, I’d rather that an LLM not automatically search for the answer online if I didn’t ask it to.
