FAQPage Schema
How do I generate GenAI images from text prompts using a command line interface?▼

To generate GenAI images from text prompts, run the genai-cli image command with your desired prompt string. This Skill uses the Nano Banana Pro model to create high-quality images directly from your terminal.

Can I use an existing image for image-to-image transformations via CLI?▼

Yes, you can perform image-to-image transformations by using the --input option with the genai-cli image command. This applies your text prompt to an existing image to create modified visual outputs.

What do I need to run batch generation workflows for image variations?▼

Batch generation and controlled variations require a configured Google GenAI API key, the genai-cli tool, and a Python environment. These dependencies enable rapid concept exploration through multiple image iterations.

Does the genai-cli tool support setting custom aspect ratios for image generation?▼

Yes, genai-cli supports custom aspect ratios for image generation using the --aspect option. You can specify dimensions like 16:9 when running your text prompt to control the output format.

What is the best way to automate rapid visual experimentation from plain prompts?▼

The best way to automate rapid visual experimentation is using genai-cli for prompt-based generation. It enables batch generation and controlled variations, allowing quick concept exploration from plain text prompts.

Why does genai-cli image generation require a keyring dependency?▼

GenAI image generation requires keyring to securely manage and retrieve your configured Google GenAI API key. This ensures safe credential storage within your Python environment for CLI access.
