Google has just unveiled Nano Banana 2 (Gemini 3.1 Flash Image), its latest AI model for image generation and editing. Combining the speed of Gemini Flash with the advanced capabilities of Nano Banana Pro, this new model promises high-quality, fast, and precise visuals across Google’s AI ecosystem.
Speed Meets Advanced Features
Previously, users had to choose: Nano Banana for speed or Nano Banana Pro for high-quality generation with complex reasoning. Nano Banana 2 eliminates that compromise.
Now, you get:
- The rapid processing of Gemini Flash
- The consistency, accuracy, and complex instruction-following of Nano Banana Pro
Practically, this means:
- Maintaining likeness for up to 5 characters in one workflow
- Preserving fidelity for up to 14 objects
- Improved instruction adherence and text rendering
- Multilingual text generation directly inside images
Resolutions can reach 4K, supporting multiple formats. The model leverages Gemini’s knowledge base, enriched in real time via Google Search, enabling precise infographics, diagrams, and current events visuals.
Example Capabilities
- Assemble up to 14 distinct objects into one coherent image
- Keep multiple characters consistent across scenes
- Generate and translate legible text within visuals for multilingual support
Think of it as the best of both worlds: speed without sacrificing quality or reasoning.
Where Nano Banana 2 Is Available
The rollout is immediate across multiple Google products:
- Gemini app: Replaces Nano Banana Pro in Fast, Thinking, and Pro modes (Pro users can still access Nano Banana Pro for fine control)
- Google Search: AI Mode & Google Lens
- AI Studio and Gemini API
- Google Cloud Vertex AI
- Flow: Default model with no credit usage
- Google Ads: Assisting campaign creation
Additionally, Nano Banana 2 is expanding to 141 new countries and territories with support for eight additional languages.
SynthID: Tracking AI-Generated Content
Google is also highlighting content provenance tools. Nano Banana 2 integrates SynthID, an invisible watermark that identifies AI-generated images. It’s now coupled with Content Credentials (C2PA), providing metadata about AI usage in image creation.
Since its November launch, SynthID verification in the Gemini app has been used over 20 million times. Google plans to integrate C2PA verification directly into the app soon, enhancing transparency for AI-generated media.
The Takeaway
Nano Banana 2 represents a major leap in AI image generation:
- Fast, precise, and high-resolution output
- Multi-character and multi-object consistency
- Built-in multilingual text capabilities
- Integrated provenance tracking with SynthID and C2PA
For designers, marketers, and developers, Nano Banana 2 is set to become the go-to model for creating professional-grade visuals across Google’s AI tools and cloud services.
With speed, accuracy, and transparency combined, Google is bridging the gap between creative freedom and reliability in AI image generation.
