Real-Time World Knowledge
Combines Google Search with image context to reduce outdated information bias and render real-world landmarks and facts more accurately.
Nano Banana 2 AI Image Model
Nano Banana 2 is Google's Gemini 3.1-based image model, built for native 4K output, strong character consistency, and Google Search enhancement. Its built-in chain-of-thought reasoning helps it parse complex prompts more accurately and generate higher-quality visuals.
Nano Banana 2 Key Features
Nano Banana 2 shines by using live web information and images to render specific topics with better accuracy.
Ultra-Wide Aspect Ratio Support
Supports ratios like 1:8, 8:1, 1:4, and 4:1, making cover banners, story panels, and long comic compositions much easier to produce.
Multi-Character and Style Consistency
Supports up to 14 reference images to keep characters, outfits, and visual style consistent across multiple frames.
High-Resolution Output with Readable Text
Supports 4K output so posters, comparison cards, and explainer graphics can balance visual depth with clear text layout.
Advanced Text-and-Image Layout
Generates clear, readable multilingual text so creative concepts adapt naturally across languages and cultural contexts. No more garbled text.
Chain-of-Thought Reasoning
Offers adjustable thinking depth. With deeper reasoning, the model performs multi-step analysis before generation for better spatial logic and stricter prompt execution.
Nano Banana 2 Core Feature Examples
Real-Time World Knowledge
Nano Banana 2 can access Google's live knowledge resources and semantically match relevant information before image generation. Compared with models that tend to invent details, it grounds outputs in real-world data and context for higher visual accuracy and credibility.
Prompt Example
Infographic of the water cycle principles
Ultra-Wide Aspect Ratio Support
Nano Banana 2 adapts to many image sizes and adds native support for extreme formats like 4:1 and 8:1, so panoramic visuals and long banners can be generated naturally without forced cropping.
Prompt Example
Highly stylized pop-art fashion portraits across multiple aspect ratios
Multi-Character and Style Consistency
Maintain stable identity consistency throughout the creative process. Nano Banana 2 supports up to 14 reference images, helping preserve character appearance, outfit details, and overall art style across multi-frame or serialized projects.
Prompt Example
Blend the listed objects and animals on the left into a farm environment
Advanced Text-and-Image Layout
Nano Banana 2 produces crisp, readable multilingual text content, helping creative ideas fit naturally across different languages and cultural contexts. Say goodbye to garbled text.
Prompt Example
Close-up shot: an eco-friendly sign made from sustainable material, with artistic illustrations of forest animals and elegant typography that reads "Respect Nature: Please Observe Wildlife from a Distance."
Chain-of-Thought Reasoning
Nano Banana 2 provides adjustable reasoning depth. By increasing thinking depth, the model runs multi-step prompt analysis before rendering, improving spatial logic and placement accuracy while handling layered instructions more faithfully.
Prompt Example
A high-saturation pop-art fashion portrait shot from a low angle, upper body framing. The subject wears a suit patterned with electric-blue spirals and vivid pink concentric circles, paired with yellow heart-shaped sunglasses and oversized pink earrings. The background is a smooth sky-blue solid backdrop with soft lighting and no heavy shadow layering.
