Overview

FLUX Kontext Pro Multi Image Editor edits or combines one or more source images from natural-language instructions and can return one to four edited images. Use it for product, campaign, social, or brand visuals that need multiple image references, source assets, or composition inputs in one edit request.

Use cases

  • Combine product, background, and style references into a new edited visual.
  • Use multiple source images to guide a campaign or ecommerce image revision.
  • Generate several composite options from the same image set and prompt.
  • Change aspect ratio while applying a multi-image edit direction.

Input tips

  • Provide one or more public image_urls that can be fetched without login.
  • Use at least two image URLs when the request should combine or compare source images.
  • Write a prompt that explains each source image's role and the desired edit.
  • Choose num_images from 1-4 when you want multiple edit options.
  • Set safety_tolerance from 1-6, where 1 is most strict and 6 is most permissive.
  • Adjust aspect ratio, guidance scale, prompt enhancement, output format, or seed only when needed.

Expected output

The AI Tool returns one or more edited images with downloadable URLs and optional content type, file name, file size, width, and height, plus the prompt used, seed, timing metadata, safety flags, and cost metadata. The shared FLUX output view renders a single image or gallery and shows prompt, seed, image count, timings, safety status when flagged, and the FLUX Kontext Pro Multi model label.

Caveats

  • Input image URLs must be public and reachable.
  • Multi-image prompts need clear roles for each source image to reduce unwanted blending or omissions.
  • Aspect-ratio changes can alter framing, composition, or fine details.
  • Generated text, logos, product details, faces, and image edges should be reviewed before use.
  • Safety tolerance and safety flags may block, alter, or mark some outputs.
