I am currently a Premium subscriber using GPT 4o-mini. A result of Ask AI concerning a grammar point in Korean was not correct. Gemini 2.5 on the other hand gave correct answer and solid explanations. My question is how much better is GPT 4o compared to GPT 4o-mini? And how is GPT 4o compared to Gemini 2.5?
If GPT 4o is comparable to Gemini 2.5 I would be willing to upgrade to Premium Plus.
I’d have to say my sense is that Gemini 2.5 is quite a bit stronger. GPT 4o does seem to me like a noticeable but modest improvement on 4o-mini when it comes to explanations. Sometimes with more obscure languages 4o and 4o-mini will disagree on the basic meaning of a word (even in the Explain tab).
I think 4o is a significant step up from 4o-mini. I’m not sure how it compares to Gemini 2.5 though.
It is possible to try out Premium Plus before committing to it by temporarily switching plans from Premium to Premium Plus on the account page. You won’t be charged immediately, instead the days you have left on your Premium plan will be applied to Premium Plus, but since Premium Plus is more expensive you’ll see that there will be fewer days remaining until you need to renew your account. If after a day of trying Premium Plus you want to switch back to Premium, you can do that and the number of days remaining on your account will increase again.
