Google took one of its biggest steps in the AI race on November 18, 2025 by officially announcing the Google Gemini 3 model. The new-generation model offers a more powerful AI infrastructure for both Google’s ecosystem and developers. Gemini 3 raises the bar not only in speed and capacity but also in deep reasoning, long context window, multimodality, and autonomous workflows.
Gemini 3 Release Date
Gemini 3 was officially released worldwide on November 18, 2025.
With the announcement:
- It was immediately integrated into the Gemini app.
- Early access was provided for Gemini Advanced / AI Premium users.
- Developers could access Gemini 3 Pro Preview via AI Studio, Google Antigravity IDE, and Vertex AI.
This makes Google one of the few companies to make a new model simultaneously available for individual users and professionals.
Gemini 3 Key Features
1. Deep Reasoning – “Deep Think” Mode
The most notable innovation. Deep Think is an advanced reasoning model that provides long-term and multi-step reasoning capabilities.
This mode enables:
- Engineering problem solving
- Complex analyses
- Multi-step planning
- Code review and debugging
This mode will be gradually rolled out as security testing is completed.
2. Much Larger Context Window
Gemini 3 offers approximately 1 million tokens in its context window. This allows comprehensive analysis of:
- 1000+ page PDFs
- Dozens of research reports
- Long documents and codebases
3. Multimodal Processing Capability
Gemini 3 integrates text, images, audio, video, and code in a single model.
This allows:
- Video analysis
- Presentation creation
- Visual detail extraction
- Code explanation and generation
4. Deeper Integration into Google Ecosystem
Gemini 3 is embedded into several Google services:
- Google Search
- Gmail
- Google Drive
- Workspace
- Android
With the Deep Research feature, users can analyze, summarize, and generate reports from hundreds of files in Drive with a single command.
5. Developers: New Antigravity IDE
Gemini 3 comes with Google’s new coding environment, Antigravity IDE.
This IDE allows developers to:
- Run AI agents independently
- Create step-by-step logs (“Artifacts”)
- Document outputs such as terminals, screenshots, and change lists
How Gemini 3 Compares to Competitors
Compared to ChatGPT 5.1
