Deep Think is based on the same foundation as Gemini 2.5 Pro, but it increases the "thinking time" with greater parallel analysis. According to Google, Deep Think explores multiple approaches to a problem, even revisiting and remixing the various hypotheses it generates. This process helps it create a higher-quality output.

Google is rolling out its most advanced version of Gemini yet, called Deep Think. It's available exclusively to AI Ultra subscribers on the Gemini app.

A version of the AI model achieved gold-medal standard at the International Mathematical Olympiad earlier this year.

The best answer I got in talking to Google about recent launches is that people expect capabilities like deep research and canvas out of modern LLM-powered offerings. That does make sense, with the other new feature announced for AI Mode being the ability to upload a PDF with your prompt.

Google's AI Mode is getting several new features this week, including Canvas for studying, image and PDF file uploads, and more.

Google says the model outperformed several of its competitors in key AI benchmark tests and a variation of the model even achieved the gold-medal standard at this year’s International Mathematical Olympiad (IMO),

Google DeepMind, Alphabet Inc.’s artificial intelligence research arm, today announced the rollout of Gemini 2.5 Deep Think, a new creative problem-solving AI model. The company stated the model is capable of addressing complex problems by considering multiple ideas simultaneously and choosing the best answer.
