Unique capability
Real-Time Web Intelligence
The only image model with built-in Google Search and Image Search grounding. Generate images anchored to real, current information.
Google Search Grounding
Uniquely powered by real-time Google Search and Image Search — a capability no other image model has.
Live world knowledge
Generate images of real events, places, products, and trending topics using current information from Google Search.
Contextual accuracy
Prompts referencing real-world concepts get grounded in accurate, up-to-date data — not training cutoffs.
Differentiators
What Makes Nano Banana 2 Different
1
Low Latency & Cost-Effective
Built on the Gemini 2.5 Flash architecture, Nano Banana 2 delivers fast generation at a fraction of the cost of comparable models — ideal for high-volume workflows and iterative creative work.
2
SynthID Digital Watermark
Every generated and edited image is automatically watermarked with Google's SynthID technology, providing verifiable content credentials (C2PA) for responsible AI use.
3
Complex Instruction Handling
Unlike models that require multiple steps, Nano Banana 2 can execute complex editing instructions in a single pass — reading diagrams, understanding spatial relationships, and applying multi-part changes at once.
4
Multimodal Input & Output
Accepts both text and images as input, and outputs text alongside images. This enables conversational image editing workflows where you can describe changes and receive both the edited image and an explanation.
Conversational workflow
Iterate Through Conversation
Unlike one-shot generators, Nano Banana 2 supports multi-turn image iteration. Describe your changes, see results, and refine — in a chat-like loop.
- 1Start with a text prompt or upload an image
- 2Ask follow-up changes in natural language
- 3Refine composition, style, and details iteratively
- 4Export any step in the conversation as final output
