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!

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.
