It’s a shame that some of these models are being depreciated. I was using gemini-2.5-flash-lite-preview-09-2025. for a specific task in my app because it was the only one that could accurately and consistently give me the output/response needed without hallucinations.

@Sajid_Mishal_PK Can you share more about the errors you are running into while trying to use 3.1 Pro? Are you using it via AI Studio or the API?

No. Why are you removing a genuinely good model? For me, Gemini 3.0 Pro is FAR better for creativity and storytelling.
