> Last week, we released a major update to Gemini 3 Deep Think to solve modern challenges across science, research and engineering. Today, we’re releasing the upgraded core intelligence that makes those breakthroughs possible: Gemini 3.1 Pro.

So this is same but not same as Gemini 3 Deep Think? Keeping track of these different releases is getting pretty ridiculous.

Deep Think is a few 3.1 models working together. It was suspected last week that Deep Think was composed using the new 3.1 model.

3.1 == model

deep think == turning up thinking knob (I think)
