Gemini Image Generation

Generate high-quality images using Google Gemini's image generation API.

When to Use This Skill

Use this skill when the user requests:

  • Image generation from text descriptions
  • Visual assets for websites or apps
  • Icons, logos, or graphics
  • UI mockups or designs
  • Any creative image generation task

Requirements

  • Google Gemini API key must be set in environment variable: GEMINI_API_KEY
  • Python package: google-genai

Instructions

When the user requests an image:

  1. Understand the requirements (subject, style, dimensions, output filename)

  2. Install the required package if needed

  3. Create and execute a Python script to generate the image using the google-genai library with model gemini-2.0-flash-exp

  4. Set appropriate aspect ratio based on user needs (1:1, 16:9, 9:16, 4:3, 3:4)

  5. Save to specified filename and inform the user of the output file location

Best Practices

  • Write detailed, descriptive prompts for better results
  • Specify style, mood, and key elements clearly
  • For UI elements, mention design style (modern, minimal, etc.)
  • For icons, specify size and simplicity level
  • Save images to organized directories
  • Create the output directory before saving if it doesn't exist

Example Prompts

Hero Image: "Modern, minimalist hero section background with gradient from deep blue to purple, abstract geometric shapes, professional tech startup aesthetic, high resolution"

Feature Icon: "Simple, clean icon representing artificial intelligence, blue and white color scheme, minimalist style, suitable for website UI"
