Having a pretty bad experience with GPT-5 and web searches – it either hallucinates or can't find web results unless I manually toggle the 'Web Search' button? And even then, responses are kinda...meh?

GPT-4o definitely didn't do this, and it seems like folks on Reddit are hating this rollout too: https://www.reddit.com/r/ChatGPT/s/zddfnoFDnR

@viticci I’ve found with past models (especially thinking ones) I would have to convince it and argue with it that iOS 26 IS THE NEXT VERSION OF iOS! It always looked at historical data and never believed me that iOS was jumping up that many numbers in one year. Looks like that hasn’t exactly been fixed and you still need to argue with GPT-5.
