I really hope they stick with the ChatGPT+ paid model. A big use of GPT to me is getting information I can already get with a search, but summarized more concisely without having to navigate various disparate web interfaces and bloated websites. It saves a lot of time for things that I don't need an expert's verified opinion on. Injecting ads into that might mess with the experience.

Maybe a freemium model where you don't get ads as a plus subscriber would work out.
