I used Gemini 2.5 Pro experimental, and I really liked it, it was the smartest model to date, but sorry how it disappeared from aistudio, how do I get it back, Gemini 2.5 Pro Preview is an extremely "Modified by moderator "model

Gemini’s response to your complaint: It sounds like you had a really positive experience with a version of Gemini you were using in AI Studio, which you refer to as “Gemini 2.5 Pro experimental,” and now you’re finding the current version, “Gemini 2.5 Pro Preview,” to be less capable for your needs…

no… just Gemini 2.5 Pro experimental > Gemini 2.5 Pro Preview I need Gemini 2.5 Pro experimental !!

nah I agree, the Pro Preview is actually unusable for coding compared to the Experimental, I thought I was the only one. It disappeared for me today after the UI was updated. I don’t know what you guys did, but it’s hilarious how much worse it became.

Yeah the difference in quality is so bad that it’s bordering on empirical and far beyond just an anecdotal opinion. It’s not just 2.5 Pro Preview though, although this new model is incredibly awful at virtually every task that I’ve tried putting to it now, compared to the old 2.5 Pro Experimental. B…

This is without a doubt the truth. I tried it and I never liked it. Something’s wrong with it. I think the best model so far is Gemini Flash 2.0. I’m using it and working on it with “Modified by moderator”

Gemini 2.5 Pro Experimental was great Gemini 2.5 Pro Preview is significantly worse, by at least 50%. …It mutilates my existing code instead of precisely tweaking it, like the Experimental could.

Gemini 2.5 Pro Preview is undoubtedly a downgrade…2.5 Pro Experimental was amazing for the PhD-level mathematical derivation tasks I was having it do, but 2.5 Pro Preview is substantially worse. Disappointing.

For me last version became super slow and unusable for large (40K) number of tokens

Unfortunately the 5-6 version of 2.5 pro is totally useless for RAG applications - just doesn’t work. It takes tons of time with auto “thinking” re-prompts that use output tokens then reaches a max token limit with internal outputs we can’t see, then returns the max output token error. This is rea…

Gemini 2.5 Pro Preview is very bad!
