Nano Banana 2 FAQs

What is Nano Banana 2?

Nano Banana 2 is an AI image generation tool developed by Tool.Video. It creates visual content using text prompts or reference images, with enhanced speed and output quality. A key feature is Google Web Search grounding, which integrates real-time information to inform generated images, allowing for current events or location-specific details.

What is the Web Search feature?

The Web Search feature connects Nano Banana 2 to Google's search engine, enabling the AI to incorporate live data into image generation. This allows prompts to reference recent events, specific locations, or current trends. For example, users can generate visuals of a city's skyline with up-to-date landmarks or depict scenes based on news topics.

What's the difference between Text-to-Image and Image-to-Image modes?

Text-to-Image generates visuals solely from descriptive text prompts. Image-to-Image uses an uploaded reference image to influence style, composition, or specific elements. The reference image can guide facial features, as prompts may include instructions like keeping faces identical. Users can upload up to nine reference images per generation, with each file limited to 5MB.

How many credits does it cost?

Credit consumption varies based on generation complexity, resolution, and feature usage like Web Search or upscaling. The interface displays a credit balance (e.g., 1407 / 20000). Specific costs per operation are not publicly fixed; users should check their account dashboard or Tool.Video's pricing page for current rates and credit packages.

Can I use generated images commercially?

Commercial usage rights are defined by Tool.Video's terms of service. Generated images may be subject to licensing restrictions. Users intending commercial use should review the legal agreements on the Tool.Video website or contact support for clarification on permissible applications and attribution requirements.

What image formats are supported for upload?

For reference images in Image-to-Image mode, Nano Banana 2 accepts common formats such as JPEG and PNG. Uploads are limited to a maximum file size of 5MB per image. Supported output download formats typically include standard raster formats like PNG and JPEG, ensuring compatibility with most editing software and web platforms.

What resolutions and aspect ratios are available?

Nano Banana 2 supports high-resolution outputs up to 4K (4096 × 4096 pixels). Common aspect ratios like 16:9 and 1:1 are available. The tool can upscale lower-resolution inputs to 4K, as demonstrated by converting a 150 × 150 pixel image to a 4096 × 4096 pixel output while maintaining detail.

Can I generate multiple images at once?

The interface provides separate "Create Image" buttons, suggesting individual generations. Batch generation capabilities are not explicitly detailed. The Playground API may allow programmatic multiple requests, but rate limits and concurrent generation policies should be confirmed in the API documentation.

What art styles are supported?

Nano Banana 2 supports a wide range of art styles, from surrealism and fantasy to specific cultural aesthetics like ukiyo-e (浮世绘) and Cuphead-inspired visuals. It also handles isometric 3D, claymation, flat vector illustration, macro photography, and advertising-style photography. Users can combine styles in prompts for hybrid effects.

How do I use the API?

The Playground API and MCP (Model Context Protocol) are available for developers to integrate Nano Banana 2 into custom applications. Access requires an API key from Tool.Video's developer portal. Detailed endpoints, authentication methods, and usage examples are provided in the official API documentation on the Tool.Video website.

Are there API rate limits?

API rate limits are implemented to ensure fair usage but specific thresholds are not listed in the public context. Limits may vary by subscription tier. Users should consult the API documentation or their account settings for precise request quotas per minute or day.

How does Nano Banana 2 compare to Nano Banana Pro?

Nano Banana 2 emphasizes faster generation and improved base results. Nano Banana Pro appears to be a more advanced version, handling complex tasks like automated city poster generation with dynamic data, intricate infographics, and multi-step compositions. Pro likely offers greater control and specialized features for professional workflows.

What is the maximum number of reference images allowed per generation?

In Image-to-Image mode, users can upload up to nine reference images simultaneously. The interface indicates this with a counter (e.g., "Reference Image(1/9)"). This allows combining multiple visual inputs to guide the AI on composition, style, or specific elements while adhering to the 5MB per file size limit.

How do I upscale an image to 4K using Nano Banana 2?

To upscale, use the Image-to-Image mode and provide a low-resolution input image. Include a prompt specifying "Upscale to 4K" or similar instructions. The tool will process the image, enhancing details and resolution to 4096 × 4096 pixels, as shown in examples where a small input yields a high-fidelity 4K output.

What are the available output image formats?

Generated images can be downloaded in standard formats suitable for editing and sharing. Commonly supported formats include PNG for lossless quality and transparency support, and JPEG for smaller file sizes. The exact formats may be visible in the download options next to the generated preview.

What is the Playground API and MCP, and how can I access them?

The Playground API allows programmatic access to Nano Banana 2's generation capabilities. MCP (Model Context Protocol) likely refers to a standardized interface for interacting with AI models. Both are accessible via Tool.Video's developer dashboard after authentication. Documentation provides endpoints for text-to-image, image-to-image, and feature toggles like Web Search.
