However, I would like to send another message regarding Gemini 2.5 Pro—where should I send it? I really hope the Google Dev team realizes that Gemini 2.5 Pro is a masterpiece among the Gemini models they have created.
Agree. We should continue sending messages and opening tickets even if it looks like Google doesn’t care. The goal is to gather as much attention as possible.
I am a Gemini pro user for somereason Gemini flash chat intrept and Gemini starts to show un wanted error like network issue while it’s working find , or sometimes error like cannot prosses information or cannot search web and this won’t fix till next day.
Do you know where I should send a message regarding the Gemini 2.5 Pro?
Is it Google AI Studio? What platform are you using?
Right now, people on the ArcaLive chat channel are freaking out saying Gemini 3.7 Flash is dead on AI Studio.
Gemini 3.7 Flash was removed without announcement, despite being it a “stable” model: https://ai.google.dev/gemini-api/docs/changelog
Maybe it was the model involved in that Irregular incident? 
That might be related to the launch of Gemini 4. There is talk that they are removing “3.7 Flash” to free up server capacity for the launch of Gemini 4 Argon.
By the way, what address should I use to contact the Google Dev team regarding Gemini 2.5 Pro?
I’m experiencing the same issue. The only difference is that Gemini 3.5 Flash isn’t even listed for me. I only have Flash 3.8, Flash 3.6, and Flash 3 available.
I hope that if these models were actually removed ahead of the Gemini 4 Argon release, they’ll eventually be brought back.
Unfortunately, it appears that Flash 3.5 and 3.7 Flash have been completely disabled. Instead of 3.5 Flash, Google recommends using 3.6 Flash or 3.8 Flash. Instead of 3.7 Flash, Google recommends using 3.8 Flash.
That’s a real shame. Personally, I liked 3.5 Flash and 3.7 Flash better than 3.6 Flash and 3.8 Flash…
They force us to use the model failed them! Replacing 2.5 Pro with 3.1 Pro is itself a joke!
That’s a real shame. Personally, I liked 3.5 Flash and 3.7 Flash better than 3.6 Flash and 3.8 Flash…
I absolutely agree!
They are violating their own policies without announcing it or providing reasons for doing so.
Gemini 3.5 Flash and Gemini 3.7 Flash both were declared “stable”, so shutdown or automatically routing requests to other models should have been announced at least 4 weeks in advance.
For Preview models it was 2 weeks; this already was violated when they shut down Gemini 3 Pro Preview.
Obviously, now even “stable” doesn’t mean anything any more. 
And when exactly did the exchange actually happen? They added it retroactively to the changes from October 8th.
– Did they treat their enterprise customers the same way? I suspect not.
Meanwhile, the extremely unreliable Gemini 3 Flash Preview is still available. I think that’s something we really don’t need to understand. 
… Maybe I’ll use Gemini 4 Argon for specific tasks – if and when we actually get it. But I certainly won’t make the mistake of using one of their models as a ‘daily driver’ again in the future.
I am, finally, incredibly disappointed and angry.

Edit: I learned that the models are still available to enterprise customers. And I submitted my feedback via Search AI Mode chat:
I’m no social media person. But if anyone set up a petition for getting Gemini 2.5 and 3.5 Flash and 3.7 Flash models back, you may point me to it.
Hello. Do you know where I should send a message regarding Gemini 2.5 Pro? I don’t know where to lodge a complaint.

All Great Models from AI Studio Playground got removed. That’s it, I am moving to Claude.
Bye Bye AI Studio and Gemini.
Once the model got deprecated, no way it is possible to bring it back!
It was possible at least once with gpt 4o. And technically Gemini 2.5 pro isn’t deprecated yet.
Hello Guys, Multiple models from 3 series got deprecated recently. But they haven’t deprecated 2.5 Series, So it shows a Positive sign that they will re-open the 2.5 pro model behind the payment wall once enough compute resources were available!
