Google released the first AI model in the Gemini 3 series last month, and it quickly became a massive hit. Even free users can try Gemini 3 Pro and Nano Banana Pro, though the access comes with daily limits.

Now it looks like Google just launched a more powerful Gemini 3 Deep Think model. Gemini 3 Deep Think is rolling out to Google AI Ultra subscribers and acts as the successor to Gemini 2.5 Deep Think.

How is Gemini 3 Deep Think better than Gemini 2.5 Deep Think?

According to Google, “This new mode delivers a meaningful improvement in reasoning capabilities, designed to tackle complex math, science and logic problems that challenge even the most advanced state-of-the-art models”

Gemini 3 Deep Think “uses advanced parallel reasoning to explore multiple hypotheses simultaneously.”

How to Use the Gemini 3 Deep Think Model?

If you are using the basic Google Gemini AI plan or the Pro plan, you won’t be able to use the latest Deep Think Model.

Gemini 3 Deep Think Model is exclusively available to all Google Ultra subscribers. So, if you have Ultra Plan, you can enable and use this new model by following these steps.

• Open the Google Gemini app on your device or visit the website.
• In the prompt field, select the ‘Deep Think’ option from the toolbar.
• Select ‘Gemini 3 Pro’ from the model selector.
• Now type the text prompt and press Enter.

Gemini 3 Deep Think offers significant upgrades in computational reasoning, especially for complex mathematical and scientific challenges. The model sets a new standard for AI-driver reasoning.
