3 and 3.1 Pro are both marked as deprecated by Google. Even if they're the best Google offers, it would be foolish to choose a model that's explicitly deprecated.
It's not a technical problem, it's a commercial one. If Google can't ship a model to replace the one they deprecated, that tells you everything you need to know about choosing a Gemini model for whatever you're trying to do.
3.1 Pro is not deprecated!
https://ai.google.dev/gemini-api/docs/deprecations
That link shows 3.1 pro listed as deprecated with no replacement model.
No, that's the "preview" version (gemini-3.1-pro-preview) aka the beta/early version before the official release of 3.1 Pro.
