What is Gemini 3?

Gemini 3 is Google’s most powerful AI system to date. It can understand text, images, videos, audio, and code in a single workflow. The model can analyze complex information, solve advanced problems, and perform tasks that require deep reasoning. Compared to previous versions, Gemini 3 offers faster responses, higher accuracy, and better long-form understanding.

It also comes with a 1 million-token context window, which allows it to read and analyse extremely long documents, notes, research papers, or videos at one time.

Key Features of Gemini 3

1. Highly Improved Reasoning

2. Multimodal Intelligence

3. Gemini 3 Deep Think Mode

Google has introduced a new advanced mode called Deep Think, which boosts the model’s reasoning to an even higher level. This mode is designed for complex scientific, analytical, or coding-related tasks and will soon be available for Google AI Ultra subscribers.

4. Stronger Performance for Developers

Developers can now build apps, websites, 3D games, and full-stack tools using simple natural-language instructions.

5. Better Long-Term Planning

Google Antigravity

Google has launched Antigravity, a new developer environment designed for agent-based coding. Using Gemini 3, developers can plan, write, and improve code, test apps, run browser-based simulations, and automate full development workflows.

This marks a shift from single-prompt usage to goal-based software development, where AI can handle end-to-end tasks with minimal support.
