Hey everyone,

We wanted to give folks a heads up that Gemini 2.5 Pro Preview 05-06 is scheduled for deprecation on June 19, 2025, given that we just launched an updated preview version Gemini 2.5 Pro Preview 06-05 (Gemini 2.5 Pro Preview in AIS) earlier this week, and will be GAing in a matter of weeks.

We recommend switching to the updated model which shows improvements across the board on key benchmarks for coding, science, multimodal understanding and reasoning. We have also improved creative writing, style and structure based on feedback from our previous releases.

Please let us know if you have any issues or concerns with switching to the updated Pro model by June 19, 2025.

These benchmarks are misleading, inflated! Claude Sonnet 4 (Extended Thinking) consistently corrects content generated by Gemini 2.5 Pro Preview 06-05 and it acknowledges its own limitations and reasoning gaps; however, the benchmark results indicate otherwise.

Providers should stop publishing benchmark results and allow the quality and standards of the models to speak for themselves. It is the quality that determines the bench results, not the other way around. I presume that you do not extensively use your own models.

The only advantage your models have is their extensive token count, which is unparalleled.
