Usage instructions

Core usage

Nano Banana Pro is an image generation and editing skill based on the Google Gemini 3 Pro Image API. It implements three core functions through command line scripts:

1. text-generated-image:useuv runimplementgenerate_image.py,pass--promptParameters describe the desired image content,--resolutionSpecify 1K/2K/4K output resolution and the result is automatically saved in PNG format.

2. Single picture editing:Add to-iThe parameters are passed into the existing image path and combined with the editing command prompt to achieve local modification, style migration or content enhancement.

3. Multi-image synthesis: Supports complex scene combinations of up to 14 input images, suitable for advanced creative needs such as creative collage and scene fusion.

API certification passedGEMINI_API_KEYEnvironment variable or configuration file management, script output includesMEDIA::Marking facilitates Moltbot's automatic attachment recognition.

Significant advantages

  • Official SDK Guarantee：Adopt Google officialgoogle-genaiThe library is protocol compliant and timely updated to avoid the uncertainty of third-party packaging.
  • Flexible resolution: 1K/2K/4K three-level output is suitable for different scenarios, covering everything from social media preview to print-grade materials.
  • Multi-image processing capability: The maximum limit of 14 images exceeds most similar tools and is suitable for complex visual storytelling and batch material integration.
  • Ecological integration:anduvModern Python package managers are deeply integrated, dependency parsing and isolation automation reduce environment configuration costs.
  • Output specification: Enforcing timestamp naming convention reduces version confusion, and MEDIA tags enable seamless integration with chatbots.

Potential Disadvantages and Limitations

  • External API dependencies: The function is fully bound to Google services. Network interruption or API changes will directly cause the service to be unavailable.
  • Key management burden: Users need to apply for and keep Gemini API keys by themselves, which involves risks of leakage and complexity of quota management.
  • No local model option: All calculations are completed in the cloud and cannot be used offline. Sensitive image content needs to be uploaded to Google servers.
  • Single output format: Only supports PNG output and lacks JPEG quality adjustment, WebP optimization, or fine control options for transparency channels.
  • Limited editorial control: Prompt-based editing relies on model understanding, and fine pixel-level adjustments or mask editing cannot be achieved.

Suitable target group

  • content creator: Bloggers, designers, and marketers need to quickly generate graphics or visual materials.
  • Developers and Product Managers: The prototyping stage requires low-cost and efficient visual concept verification.
  • AI workflow integrator: Technical users who have incorporated Moltbot or similar Agent platforms into their daily toolchain.
  • Education and Research: Academic scenarios where sample images need to be generated in batches for use in teaching materials or data set construction.

Risks of use

  • Performance fluctuations: Image generation time is affected by network latency and Google API load, and 4K resolution may cause timeouts or retries.
  • Cost accumulation: The Gemini API is billed on a per-call basis, and high-frequency usage or high-resolution output may incur unexpected charges.
  • Content compliance: Generated content is subject to Google usage policies and specific topics may trigger review or rejection.
  • File overwrite: The existence of the target path is not checked, and repeated runs may accidentally overwrite historical output.
  • Dependency version lock：google-genai>=1.0.0Loose constraints may introduce breaking changes in the future.

Safety review

Core usage

Nano Banana Pro is an image generation and editing tool based on the Google Gemini 3 Pro Image API. It implements the following functions through command line scripts:

image generation:useuv run generate_image.py --prompt ""Generate new images, supporting 1K/2K/4K resolutions.

image editing:pass-iThe parameters are passed in to a single picture and combined with the prompt words for intelligent editing and modification.

Multi-image fusion: Supports synthetic creation of up to 14 input images, suitable for complex tasks such as scene combination and style transfer.

Integrated features:script output containsMEDIA:Marked rows can be automatically recognized by Moltbot and display images directly on supported platforms.

Significant advantages

  • Official API endorsement: The bottom layer calls Google Gemini 3 Pro, and its image quality and understanding capabilities are among the first in the industry.
  • Complete security architecture: API Key is only read through environment variables, with zero hard-coding risk; the code has passed S+ level security certification
  • Reliance on simplicity and credibility: Use onlygoogle-genaiandpillowTwo official maintenance libraries, no supply chain attack surface
  • Flexible resolution: Three levels are available from fast preview (1K) to high-quality output (4K)
  • Sufficient upper limit for multiple images: The maximum synthesis limit of 14 pictures meets most creative scenarios

Potential Disadvantages and Limitations

  • Strong network dependence: Must be connected to Google Cloud Service, cannot be used offline, and may be restricted in some areas
  • Cost accumulation: Gemini 3 Pro is a paid API, and high-frequency calls will incur ongoing fees.
  • File overwrite risk: The current version directly overwrites the output file with the same name, without secondary confirmation.
  • Simple error message: When the API call fails, the log is not detailed enough, and troubleshooting requires experience.
  • Platform binding: MEDIA automatic attachment function relies on specific chat platform support

Suitable for the crowd

  • Designers and creators who need to quickly generate concept maps, illustrations, and product images
  • Technical users who want to batch process image editing
  • Teams that have integrated the Google AI ecosystem into their workflows
  • Enterprise environments that have high requirements for code security and are unwilling to use closed source tools
