# Imagen 4 Image Generator Generate images from text prompts using Imagen 4 on Vertex AI, save to CC Pages, and send to Discord. ## Usage Call the generation script directly: ```bash ~/.claude/scripts/imagen-generate.sh "your prompt here" ``` ### Options ```bash # Basic generation (1 image, 1:1 aspect ratio, fast model) ~/.claude/scripts/imagen-generate.sh "a cute cat sitting on a GPU server" # Custom aspect ratio: 1:1, 3:4, 4:3, 16:9, 9:16 ~/.claude/scripts/imagen-generate.sh "TPU pod in a datacenter" --aspect 16:9 # Multiple images (1-4) ~/.claude/scripts/imagen-generate.sh "neural network visualization" --count 2 # Model tier: fast (default, $0.02), standard ($0.04), ultra ($0.06) ~/.claude/scripts/imagen-generate.sh "detailed architecture diagram" --model standard # High resolution (2K/4K, only standard and ultra models) ~/.claude/scripts/imagen-generate.sh "landscape photo" --model standard --resolution 2048x2048 # Custom output filename ~/.claude/scripts/imagen-generate.sh "logo design" --output my-logo # Disable prompt rewriter (use exact prompt) ~/.claude/scripts/imagen-generate.sh "minimal line drawing" --no-rewrite # Combine options ~/.claude/scripts/imagen-generate.sh "B200 GPU rack in datacenter, photorealistic" --aspect 16:9 --model standard --count 2 ``` ### Output - Images saved to `/var/www/cc/assets/imagen/` as PNG - Returns the public URL: `https://cc.higcp.com/assets/imagen/{filename}.png` - When called from Discord context, send the URL using `send-to-discord.sh --plain` ### Workflow for Discord ```bash # 1. Generate image URL=$(~/.claude/scripts/imagen-generate.sh "your prompt" --aspect 16:9) # 2. Send to Discord ~/.claude/scripts/send-to-discord.sh --plain "$URL" ``` Or just run the script — it prints the URL which you can share. ## Models - **`imagen-4.0-fast-generate-001`** (default) — Fast, $0.02/image, 1K resolution, 150 QPM - **`imagen-4.0-generate-001`** (standard) — Best quality, $0.04/image, up to 4K resolution, 75 QPM - **`imagen-4.0-ultra-generate-001`** (ultra) — Highest quality, $0.06/image, up to 4K resolution, 30 QPM ## Supported Aspect Ratios All models: `1:1`, `3:4`, `4:3`, `16:9`, `9:16` ## Supported Resolutions - **fast**: 1024x1024, 896x1280, 1280x896, 768x1408, 1408x768 - **standard/ultra**: Above + 2048x2048, 1792x2560, 2560x1792, 1536x2816, 2816x1536 ## Prompt Tips - Be specific and descriptive: "a red sports car on a mountain road at sunset, photorealistic" > "car" - Imagen 4 has a built-in prompt rewriter that enhances your prompt (enabled by default) - Supports Chinese prompts natively (simplified & traditional) - For technical diagrams, add style keywords: "technical illustration", "blueprint style", "infographic" - To disable prompt enhancement, use `--no-rewrite` ## Prerequisites - `google-genai` Python SDK (already installed for STT) - GCP project with Vertex AI API enabled - Application Default Credentials configured ## Files ``` ~/.claude/scripts/ └── imagen-generate.sh # Image generation script /var/www/cc/assets/imagen/ # Generated images (web-accessible) ```
