SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Editing existing visuals can be time consuming and requires multiple tools. This Skill enables users to modify images quickly by describing changes with natural language prompts, leveraging fal.ai Gemini 3 Pro for automated edits.

Core Features & Use Cases

  • Text-guided image edits: modify attributes, objects, backgrounds, or styles based on a prompt.
  • Multi-image context: supports editing with multiple input images to preserve context.
  • Use case: a designer wants to alter the color grade of a product photo or remove an unwanted object across a batch of images.

Quick Start

Ensure FAL_KEY is set in your environment. Then call the Falcon API with a prompt and one or more image URLs, e.g. curl --request POST --url https://fal.run/fal-ai/gemini-3-pro-image-preview/edit --header "Authorization: Key $FAL_KEY" --header "Content-Type: application/json" --data '{"prompt":"Change the background to blue sky","image_urls":["https://example.com/image1.jpg"]}'.
