Hello, Since March 16–17, 2026, I have noticed a significant increase in the costs for API calls using the gemini-3-flash-preview model. We do not use the caching system or the Google search system.

I have the same problem (Note that the token use on yesterday increased %15 compared to march 5, while the costs has increased almost 6 times) (Note2 : i use gemini-3-flash-preview model) [Screen Shot 2026-03-21 at 13.10.59 PM]
