The gemini 2.5 pro model cannot handle my previous complex workflow information, resulting in a status 500 error

Now I cannot use the gemini2.5pro model. I am developing a dialogue program based on GEMINI API, similar to custom gemini, which can add some industry rules. Three hours ago, I could use the model gemini 2.5 pro preview 06-05 normally and complete my work, but now I suddenly cannot reply to my information flow, while gemini 2.5 flash can still reply according to the information flow. I don’t know if you are adjusting the version of the 2.5 pro model, which caused this problem. You can see the two images below. I replaced your latest 2.5 pro model (not 2.5 pro preview) in the development environment and still cannot process it, but three hours ago I could accept the answer content normally.


Hi @user2145,

Welcome to the Forum, Please wait and try your request again as a 500 error usually indicates an unexpected error on Google’s side.

Thank you!

It works fine now. It should be that Google is replacing the 2.5pro model with a new version, which caused some problems. :face_with_raised_eyebrow:
