The Gemini 3 update marks one of Google’s most important AI releases of 2025, expanding the Gemini model family across Search, apps, research tools, and developer platforms. With this update, Google is clearly prioritizing speed, multimodal understanding, and deeper reasoning as core requirements for modern AI systems.
In December 2025, Google confirmed that Gemini 3 is now powering multiple consumer and enterprise-facing products, signaling a long-term move away from single-purpose AI tools toward integrated AI platforms.
Gemini 3 Update: Gemini 3 Flash Becomes the Default Model
As part of the Gemini 3 update, Google introduced Gemini 3 Flash as the default AI model for the Gemini app and AI Mode in Google Search. The Flash model is optimized for fast responses and low latency, making it suitable for everyday tasks such as summarization, quick queries, and multimodal interactions.
Gemini 3 Flash supports combined inputs across text, images, audio, and video, allowing users to ask more complex questions without switching tools or workflows.
Gemini 3 Update Introduces Deep Think Reasoning
Another major addition in the Gemini 3 update is Gemini 3 Deep Think, a specialized reasoning mode available to Google AI Ultra subscribers. Deep Think focuses on iterative reasoning, enabling the model to work step by step through complex problems in mathematics, science, and logic.
This mode is designed for researchers, developers, and advanced users who require analytical depth rather than instant responses.
Gemini 3 Update Powers NotebookLM Upgrade
Google also upgraded NotebookLM as part of the Gemini 3 update, rebuilding the research assistant on top of the Gemini 3 architecture. The update improves long-context understanding and allows users to export research sources into structured data tables compatible with Google Sheets.
This positions NotebookLM as a more capable research and productivity tool within Google’s AI ecosystem.
Multimodal Tools Expanded in the Gemini 3 Update
The Gemini 3 update includes enhanced image editing and visual interaction features. Users can now circle, draw, or annotate directly on images to request precise changes, reflecting improvements in Gemini 3’s visual and spatial reasoning capabilities.
These tools highlight Google’s push toward AI systems that understand visual context as naturally as text.
Developer Access Expands With the Gemini 3 Update
For developers and enterprises, the Gemini 3 update expands availability through Google AI Studio and Vertex AI. The updated APIs support multimodal function calling, image-based code execution, and richer AI responses designed for agent-style applications.

Why the Gemini 3 Update Matters
The Gemini 3 update confirms a broader industry shift. AI systems are no longer evaluated solely on output generation, but on how well they integrate speed, reasoning, and multimodal understanding into a single workflow. on Google Blog
Google’s approach reflects growing demand for AI platforms that support continuous, connected productivity rather than isolated tools.
