image-generation

name: image-generation description: Generate images from text descriptions using AI. Use when the user asks to create, generate, draw, or design an image, illustration, icon, or any visual content.

Image Generation

Generate images using the generate_image tool.

Parameters

Prompt Structure

Build prompts with these 5 components:

1. Style/medium — photograph, illustration, watercolor, digital art, vector, 3D render
2. Subject — who or what, with specific details (pose, clothing, expression, material)
3. Setting — location, time of day, atmosphere, weather
4. Action — what is happening in the scene
5. Composition — camera angle, framing (close-up, wide shot, bird's eye, low angle)

Example: "Cinematic photograph of a futuristic city skyline at golden hour, with flying vehicles crossing between skyscrapers, shot from a rooftop balcony with shallow depth of field, warm amber tones"

Aspect Ratio Guide

Choose based on the intended use:

• 1:1 — social media posts (Instagram feed, profile pictures)
• 16:9 — banners, landscape, YouTube thumbnails, presentations
• 9:16 — stories, reels, vertical mobile content
• 4:3 — classic photo, presentations
• 3:2 — standard photography
• 4:5 — Instagram portrait posts
• 21:9 — ultrawide cinematic banners

Reference Images

Reference images provide visual context. The model sees them BEFORE the text prompt.

For logos and brand assets:

• Add the logo path to reference_images
• In the prompt, be explicit: "Place the provided logo at the bottom center of the image. Do not modify the logo's shape, colors, or proportions — use it exactly as provided, only resize it to fit the composition"
• Never describe what the logo looks like — just describe where and how to use it

For style references:

• Add the style image to reference_images
• In the prompt: "Generate in the same visual style as the provided reference image"

For editing existing images:

• Add the image to reference_images
• Describe the desired changes: "Change the background to a sunset beach scene while keeping the subject unchanged"

Text in Images

• Enclose exact text in quotes: Write the text "SALE 50% OFF"
• Describe typography explicitly: "bold white sans-serif font with a subtle drop shadow"
• Specify placement: "centered at the top of the image"
• Keep text minimal for social media — one headline maximum to avoid clutter

Google Search Grounding

Set google_search: true when the image needs real-time or factual data:

• Stock prices and financial charts
• Weather forecasts
• Current events and news topics
• Sports scores and standings
• Real product data

Example: "Visualize the Bitcoin price trend over the last 7 days as an infographic"

Quality Tips

• Be descriptive, not repetitive. Don't use "4K, masterpiece, trending on artstation" — the model understands natural language. Describe the scene vividly instead.
• Use photographic language for realistic images: camera model, focal length (85mm f/1.4), lighting setup (soft key light with rim light), film stock (Kodak Portra 400)
• Be specific about colors and materials: "matte black aluminum with brushed gold accents" instead of just "dark with gold"
• Resolution matters: Use size: "2K" for social media, size: "4K" for print-quality assets
• Composition keywords: rule of thirds, symmetrical, leading lines, negative space, flat lay, isometric

What NOT to Do

• Don't describe reference images — just describe how to USE them
• Don't add quality spam keywords — focus on scene description
• Don't leave aspect ratio unset for social media — always pick the right ratio
• Don't put too much text in the prompt for text-in-image — keep it to one headline
• Don't forget to use google_search when the image needs current real-world data
