My account has constant glitches with models - Pro 3.1 model missing again. It started couple weeks ago when I’ve been on Plus subscription. I thought OK that might be new politics let’s upgrade to Pro subscription. After that model been available for a week but now it’s disappeared. What is going on with your models?!
Hi @Shep,
Gemini 3.1 Pro has been retired and is no longer selectable in Gemini Enterprise. There is no supported way to continue using this model.
We recommend transitioning to Gemini 3.8 Flash. To help bridge any performance differences and achieve similar depth:
- Increase reasoning capacity: Use the highest available thinking setting for complex, multi-step, or analytical tasks.
- Refine key prompts and Gems: Newer generations interpret instructions differently. Adding explicit structural constraints, requesting step-by-step logic, or supplying few-shot examples will yield significantly better output.
We recognize that Flash behaves differently from 3.1 Pro across certain tasks, and your feedback is essential as we continue tuning performance.
