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.
While it’s understandable to be frustrated when a tool you liked changes, making claims like one model being the “smartest” and another being “extremely stupid” isn’t very helpful without specific examples. Here’s why providing evidence is crucial:
- Subjectivity: Terms like “smart” and “stupid” are subjective. What one person finds intelligent, another might not, depending entirely on the task and the input provided. The model might excel at certain tasks but perform poorly on others.
- Reproducibility: For anyone (including Google’s team or other users on the forum) to understand your experience, they need to see what you were doing. Without concrete examples, no one can reproduce the issue or even understand the specific nature of the problem.
- Identifying the Actual Issue: Was it a specific type of prompt? A particular reasoning task? Coding? Creative writing? The perceived difference in performance could be due to changes in how the model handles specific instructions, data updates, or even subtle differences in how you’re prompting the new version compared to the old one.
- Model Versions: Model names and access can change, especially for preview or experimental versions. It’s possible the “experimental” version you were using was an earlier iteration that has since been updated or replaced by the current “Gemini 2.5 Pro Preview.” These updates aim for overall improvement, but sometimes specific capabilities might shift.
- Actionable Feedback: To provide useful feedback or get help, you need to show the difference. Ideally, you would provide:
- The exact prompt(s) you used with the “experimental” model.
- The successful output you received from that model.
- The same prompt(s) used with the current “Gemini 2.5 Pro Preview”.
- The unsatisfactory output you received from the current model.
- An explanation of why the new output is worse for your specific needs.
Without this kind of detailed, reproducible evidence, your post reads more like a complaint than a bug report or a request for help. It’s impossible for others to validate your experience or offer constructive suggestions. Unfortunately, getting back access to a specific, potentially internal or deprecated, experimental version is usually not possible. The best path forward is to clearly document the shortcomings you’re experiencing with the current model using specific examples.
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.
But also, what on Earth happened to the UI and why did they decide to update it? It’s not just that the old UI was incredible but that the new UI they have is seriously awful like I have no idea what’s behind their thought process on the changes. Virtually all of the important tools are now hidden behind sub-buttons hidden behind buttons, but in trying to ‘simplify’ the workspace they’ve really stripped out easy accessibility to a lot of the important functionality and now you have to ‘find’ it by looking through their subpar UI.
