New Delhi: Google has recently announced that they have begun rolling out its Gemini 3 Deep Think mode to Google AI Ultra subscribers within the Gemini application itself. This latest mode delivers enhanced reasoning capabilities and is specifically designed to handle those complex maths, science and logic-based problems. Deep Think was previewed last month during the release of Google’s Gemini 3 AI models, but is only now becoming available to users. Google also stated that the latest Gemini 3 Deep Think mode builds upon the earlier Gemini 2.5 Deep Think variants and uses advanced parallel reasoning to evaluate multiple hypotheses at once.

This will help the AI assistant work through intricate equations, multi-step logic problems and other tasks that require deeper contextual understanding. It comes with the Humanity’s Last exam: 41.0% with code execution. ARC-AGI-2: 45.1% with code execution. Google has also added that Ultra subscribers can try Gemini 3 Deep Think starting today by selecting Deep Think in the prompt bar and choosing Gemini 3 Pro in the model selector.
Google released its Gemini 3 AI model last month, bringing a significant upgrade to the Gemini application, Search’s AI Mode and several Google services. Gemini 3 has been engineered to provide more intelligent, more accurate and more natural responses than previous generations. The company also stated that the model delivers significantly deeper reasoning, enabling it to understand user intent more effectively, follow lengthy instructions with better reliability and break down complex tasks with fewer follow-up prompts.
Gemini 3 also features improved multimodal understanding, enabling it to process and interpret text, photos, screenshots, PDFs, and videos with greater accuracy. This allows capabilities such as summarising long documents, analysing detailed images or explaining visual elements like graphs and charts. Gemini 3 now supports larger context windows and improved planning, helping it complete more extensive tasks, including organising information, generating structured plans or assisting with research with reduced errors. Google also said that Gemini 3 is its most secure model to date, with better defences against misleading prompts and more robust handling of sensitive or high-risk queries.
