I run complicated, messy PDFs through these models. 2.5 Pro required a lot of kludgy hacks to get it to fully "see," but from 3.1 pro on I've removed many of them and haven't spotted problems.
3.7 Flash scores better than 3.1 pro on most benchmarks, leading me to believe that even if your OCR requires reasoning to interpret text or data, 3.7 Flash is probably going to be better.
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.
That link shows 3.1 pro listed as deprecated with no replacement model.
these models aren’t successors and barely have a common ancestor, they are independently baked in the training oven and assigned a semantic version randomly by someone trying to show initiative but not trying to do on the toes of the last guy who got promoted first
So 3 pro is outdated and will likely never exit preview
The “flash” and “lite” models are the real “pro” in colloquial ideas of fleshed out and capability, at this point.
they’re better, faster and cheaper, larger context windows keeping up with the industry and more
3.7 Flash is better at coding, sure, but AI is not just for coding.
