Image Editor

Edit and transform existing images using text prompts with Google's Gemini 3 Pro model via fal.ai.

See references/fal-api.md for setup, Python patterns, and error handling.

API Endpoint

fal-ai/gemini-3-pro-image-preview/edit

Parameters

Required

• prompt (string): The editing instruction describing what changes to make
• image_urls (array of strings): URLs of the images to edit (use fal_client.upload_file() for local files)

Optional

Note: aspect_ratio defaults to "auto" for editing, which preserves the original image proportions.

CLI Script

python3 scripts/fal_generate.py \
    --endpoint edit \
    --prompt "Add snow to this mountain scene" \
    --image /path/to/mountain.jpg \
    --output edited.png

Tips

• Be specific about what changes you want: "make the sky sunset orange" is better than "change the sky"
• Use aspect_ratio: "auto" (the default) to preserve original image proportions
• Multiple images can be provided for context, style transfer, or combining elements
• Set enable_web_search: True for style-grounded edits ("make it look like a Monet painting")
• Always include safety_tolerance: "6" for maximum creative flexibility
• Upload local files with fal_client.upload_file() before passing to image_urls
