Gemini 3 Deep Think rolls out to paid subscribers

After launching Gemini 3 in late November, Google is rolling out its latest Deep Think mode to AI Ultra subscribers.

Now available in the Gemini app for anyone shelling out $250 a month for the pro plan, Gemini 3 Deep Think is the supercharged mode of Google's latest large language model (LLM), designed to tackle more complex problems. According to the company, it "uses advanced parallel reasoning to explore multiple hypotheses simultaneously."

The latest update after Gemini 2.5, Gemini 3 Deep Think has a few bragging rights, as Google says it scored 41 percent on the extremely difficult LLM benchmark, Humanity’s Last Exam.

If you're paying for AI Ultra, you can try Gemini 3 Deep Think in the Gemini app by hitting the prompt bar and selecting the dropdown option.

Demand is high for Google's AI tools of late, despite the company joining competitors like Anthropic and OpenAI in taking home an average AI safety report card this week. The rollout comes days after Google had to cap access to its next gen image generator, Nano Banana, temporarily dropping the number of free image prompts from three to two (this didn't affect Google AI Pro or AI Ultra plan subscribers). Google says its Gemini app is used by 650 million users every month, and with the arrival of Gemini 3, rival OpenAI reportedly lost 6 percent of its users in a week.
