Nick_D 1 Hi Everyone -
Firstly, I want to give my thanks to the Gemini team for providing access to such great models. It has been so helpful.
We have some very specific workflows that rely on Gemini 2.5 Flash. Our internal benchmarks show that Gemini 3 flash does not perform as well (even after attempting to tweak prompting following the new prompting guidelines and other changes).
I am sure there are others with the same experience as well, and there is no easy switch.
It would be extremely appreciated if 2.5 flash was not discontinued.
Yes, even our own benchmarks show that the closest model in latency + performance, which is 3.1 flash lite, doesn’t even come close to 2.5 Flash. Seeing issues with thoughts leaking out. I should say, 2.5 flash has been the best model we’ve seen for all round usage and works pretty well with most of tasks.
I am pretty sure, a huge chunk of their traffic and usage comes from this model. Would really appreciate it if the Google team can retain this model for much longer time.
Preach. Retiring 2.5 Flash will be such a massive loss. It’s the only low latency model that is deployed in Australia. I’m able to get 300-400ms completions from 2.5 Flash, making it suitable for voice agents.
3.5 Flash offers 600-700ms completions and doesn’t even get an Australian deployment, so the actual latency is closer to 700-800ms, completely breaking the voice agent use case.
There is honestly no other model deployed in this part of the world that comes close to the quality that 2.5 Flash offers for low latency applications.
