Model Description

Nano Banana 2 is a high-performance AI image generation and editing model built on Gemini 3.1 Flash Image architecture. It delivers outstanding generation speed alongside professional-grade visual quality. Natively supporting text-to-image, image-to-image and multi-reference image fusion, this model features 4K native output, strong character & object consistency, advanced comprehension of complex prompts and accurate multi-language text rendering. It is widely used for marketing posters, brand visuals, product shots, storyboards, infographics and other professional visual creation tasks.

Powered by Google search semantic capabilities, the model accurately follows real-world common sense, landmarks, scientific facts and historical details to reduce unrealistic artifacts. Equipped with an exclusive thinking reasoning module, it thoroughly interprets complicated instructions and optimizes spatial composition, object arrangement and fine details, making it an all-round solution for both mass creative production and high-precision visual design.

Key Features

1. Native 4K Ultra HD Output Supports multiple resolutions including 512px, 1K, 2K and 4K (4096×4096). It is compatible with standard and extreme aspect ratios such as 1:1, 16:9, 9:16, 4:1, 1:4, 8:1 and 1:8, perfectly fitting banners, mobile long images, panoramic visuals and more without composition damage.

2. Real-world Knowledge Integration Backed by semantic search technology, it faithfully restores landmarks, scientific principles, historical details and physical parameters. Ideal for creating credible infographics, science visuals, real-scene images and product diagrams with fewer factual errors.

3. Strong Multi-subject Consistency Stably retains facial features, outfits, props and IP characteristics across sequential creations and multi-character scenes. It accepts up to 14 reference images to unify style, appearance and layout, great for comics, storyboards and serial brand visuals.

Limitations & Notes

1. Prompt Dependency: Output quality relies heavily on detailed prompts. For complex scenes, structure your description in order: subject, action, scene, composition, lighting and style.
2. Speed & Accuracy Trade-off: Higher reasoning strength improves details for complex images but slightly increases generation time. Use default settings for simple creations to boost speed.
3. Reference Image Rules: A maximum of 14 reference images per task. Large style differences between references may weaken visual consistency.
4. Usage Compliance: Please use the model legally and ethically. Do not generate violent, pornographic, illegal or copyright-infringing content. Always review all outputs before use.
