Google has launched Gemini 3, its most advanced AI model yet, featuring the new Deep Think mode, enhanced multimodal learning, stronger coding tools, and agent-based automation across its ecosystem.
Gemini 3: Major Upgrades
Gemini 3 builds on earlier milestones—such as multimodal support, long-form context handling, and higher-level reasoning—with marked improvements in step-by-step reasoning, multimodal interpretation, custom interface generation, and developer resources. For the first time, Gemini 3 is rolling out simultaneously across Google Search (AI Mode), the Gemini app, AI Studio, Vertex AI, and Google’s new agentic development environment, Antigravity.
Deep Think Mode: AI That Analyzes Deeper
The headline feature, Deep Think, enables Gemini 3 to spend more computation effort on difficult analytical or scientific tasks, yielding superior step-by-step reasoning and accuracy. In evaluations, Deep Think achieved 41.0% on Humanity’s Last Exam (no tools) and 93.8% on GPQA Diamond, outpacing Gemini 3 Pro and even top competitors. This advanced mode is in extended safety review and will roll out to Google AI Ultra subscribers.
Multimodal Workflows and Interface Generation
With its unified multimodal architecture, Gemini 3 can reason across text, images, audio, video, and code within a single model, supporting use cases like:
- Converting handwritten notes into structured documents.
- Summarizing long videos and lectures.
- Generating dynamic visuals and interactive tools directly in Google Search via AI Mode.
Gemini 3 also introduces new interface-generation options in the Gemini app, including Visual Layout (magazine-style arrangements) and Dynamic View (agent-powered interactive interfaces).
Developer and Enterprise Enhancements
For developers, Gemini 3 now delivers stronger coding, zero-shot capabilities, and agentic workflows, excelling in benchmarks such as WebDev Arena and SWE-bench. The new Antigravity environment allows Gemini 3 to plan, code, execute, and validate outputs end to end, integrating various Gemini components for seamless automation.
Agentic Automation: Gemini Agent
The new Gemini Agent, based on Project Mariner, is capable of multi-step automation, handling tasks such as organizing emails, managing calendars, extracting travel data, and drafting replies. The agent confirms sensitive actions and is designed to avoid tool-use drift during long-term task management.
Availability and Safety
Gemini 3 Pro is rolling out globally in the Gemini app and AI Mode, for Google AI Plus, Pro, and Ultra subscribers. Deep Think, due to its advanced reasoning power, remains in safety review but will be available to Google AI Ultra users. Gemini 3 brings improved resistance to prompt manipulation, cyberattack protections, and is being audited by external organizations for safety.
Impact and Roadmap
Google CEO Sundar Pichai emphasized that Gemini 3 is part of a broader AI roadmap focused on intelligence, agentic systems, and personalization. Gemini now powers multiple Google products at scale, with over 13 million developers building on its platform and feature-rich generative AI available to billions of users worldwide.
