Purpose
Nano Banana 2 is an AI image generation and editing platform, officially positioned as a 4K image generation tool for posters, advertisements, storyboards, and brand assets. It is powered by Gemini 3.1 Flash Image, with emphasis on in-image typography, character consistency, and the ability to continuously edit using natural language.
Main Capabilities
- In-image text: Officially stated to directly control font style, tone, and font size, generating clear, readable, and accurate multi-line text, suitable for posters, event drafts, and holiday cards, and can perform multilingual translation and localization of text within images.
- Resolution and aspect ratios: Supports native 4K resolution and 14 aspect ratios. Officially stated resolution support ranges from 512px to native 4K, and provides 2K/4K upscaling.
- Subject consistency: Officially stated to maintain likeness across up to 5 characters and preserve fidelity for up to 14 objects, used for continuous frames such as storyboards.
- Natural language editing: Both models support conversational editing; simply describe modifications in everyday language, with no need for complex software and no need to regenerate from scratch.
- Real-world knowledge and search: Officially stated to be driven by the Gemini knowledge base and combined with real-time information from Google Search, used to render trending topics and generate infographics containing current data.
- Multiple reference images (Pro): Nano Banana Pro provides a wider context window and can upload up to 14 reference images, such as logos, color palettes, and character design sheets, for brand consistency.
How to Use
The official three-step process is:
- Describe the idea: Write a detailed prompt in natural language, specifying the subject, lighting, composition, and style.
- Choose a model and generate: Choose Nano Banana 2 for fast image output within 3-4 seconds, or choose Nano Banana Pro for studio-level precision; multiple aspect ratios can be selected, up to 4K.
- Edit, refine, and export: Modify with natural language instructions, switch between Nano Banana 2 and Nano Banana Pro within the workflow, and download at production-ready quality. Officially, it is also recommended to write prompts by "thinking like a creative director" and avoid piling up tags; for Nano Banana Pro, the ICS framework can be used, namely specifying Image type (image type, such as blueprint, infographic, poster), Content (content, such as source data or subject), and Style (style, such assurvival guides, cinematic, editorial style). The official recommendation is also to use an "edit rather than reroll" approach, for example, "keep the composition, but change the lighting to golden hour."
Model comparison
- Nano Banana 2 vs. the original Nano Banana: The official description says the original can generate images, but text rendering is blurry, and details break down at larger sizes; Nano Banana 2 is based on Gemini 3.1 Flash, fixes these problems, and offers clear multi-line text, sharper edges, and native 4K.
- Nano Banana 2 vs. Nano Banana Pro: The official description says Nano Banana 2 takes 3-4 seconds to generate and handles most creative tasks well; Nano Banana Pro takes 10-20 seconds, but produces studio-grade results with richer textures and stronger subject fidelity. Choose the former when you need speed, and switch to the latter when you care about every pixel.
- Nano Banana 2.1 vs. Nano Banana 2: The official recommendation is to compare the two when you need to understand what has been updated and then choose a model for a project.
Use cases
The officially listed scenarios include:
- Marketing and advertising: Use Nano Banana 2's speed to generate ready-to-publish visual assets in minutes; use Nano Banana Pro to load a complete brand style guide and produce assets fully aligned with the brand tone.
- Storyboards and storytelling: Maintain character consistency across scenes, first use Nano Banana 2 to quickly draft storyboard frames, then use Nano Banana Pro's studio-grade control to polish key shots.
- Product design and visualization: Generate exploded views, lifestyle scene mockups, and product renderings from text descriptions; Nano Banana Pro's support for 14 reference images helps maintain visual consistency.
- Data visualization and infographics: Both use real-time web search to generate infographics containing current data and turn notes into polished diagrams.
Plans and limits (according to the official page)
The official page lists three tiers:
