Generate or edit images using AI models (FLUX, Gemini). Use for general-purpose image generation including photos, illustrations, artwork, visual assets, concept art, and any image that isn't a technical diagram or schematic. For flowcharts, circuits, pathways, and technical diagrams, use the scient

Generate Image Generate and edit high quality images using OpenRouter's image generation models including FLUX.2 Pro and Gemini 3 Pro. When to Use This Skill Use generate image for: Photos and photorealistic images Artistic illustrations and artwork Concept art and visual concepts Visual assets for presentations or documents Image editing and modifications Any general purpose image generation needs Use scientific schematics instead for: Flowcharts and process diagrams Circuit diagrams and electrical schematics Biological pathways and signaling cascades System architecture diagrams CONSORT diagrams and methodology flowcharts Any technical/schematic diagrams Quick Start Use the scripts/generate image.py script to generate or edit images: This generates/edits an image and saves it as generated image.png in the current directory. API Key Setup CRITICAL : The script requires an OpenRouter API key. Before running, check if the user has configured their API key: 1. Look for a .env file in the project directory or parent directories 2. Check for OPENROUTER API KEY=<key in the .env file 3. If not found, inform the user they need to: Create a .env file with OPENROUTER API KEY=your api key here Or set the environment variable: export OPENROUTER API KEY=your api key here Get an API key from: https://openrouter.ai/keys The script will automatically detect the .env file and provide clear error messages if the API key is missing. Model Selection Default model : google/gemini 3 pro image preview (high quality, recommended) Available models for generation and editing : google/gemini 3 pro image preview High quality, supports generation + editing black forest labs/flux.2 pro Fast, high quality, supports generation + editing Generation only : black forest labs/flux.2 flex Fast and cheap, but not as high quality as pro Select based on: Quality : Use gemini 3 pro or flux.2 pro Editing : Use gemini 3 pro or flux.2 pro (both support image editing) Cost : Use flux.2 flex for generation only Common Usage Patterns Basic generation Specify model Custom output path Edit an existing image Edit with a specific model Edit with custom output Multiple images Run the script multiple times with different prompts or output paths: Script Parameters prompt (required): Text description of the image to generate, or editing instructions input or i : Input image path for editing (enables edit mode) model or m : OpenRouter model ID (default: google/gemini 3 pro image preview) output or o : Output file path (default: generated image.png) api key : OpenRouter API key (overrides .env file) Example Use Cases For Scientific Documents For Presentations and Posters For General Visual Content Error Handling The script provides clear error messages for: Missing API key (with setup instructions) API errors (with status codes) Unexpected response formats Missing dependencies (requests library) If the script fails, read the error message and address the issue before retrying. Notes Images are returned as base64 encoded data URLs and automatically saved as PNG files The script supports both images and content response formats from different OpenRouter models Generation time varies by model (typically 5 30 seconds) For image editing, the input image is encoded as base64 and sent to the model Supported input image formats: PNG, JPEG, GIF, WebP Check OpenRouter pricing for cost information: https://openrouter.ai/models Image Editing Tips Be specific about what changes you want (e.g., "change the sky to sunset colors" vs "edit the sky") Reference specific elements in the image when possible For best results, use clear and detailed editing instructions Both Gemini 3 Pro and FLUX.2 Pro support image editing through OpenRouter Integration with Other Skills scientific schematics : Use for technical diagrams, flowcharts, circuits, pathways generate image : Use for photos, illustrations, artwork, visual concepts scientific slides : Combine with generate image for visually rich presentations latex posters : Use generate image for poster visuals and hero images
