FireRed Image Edit enables precise image editing with natural-language instructions, supporting both English and Chinese prompts with multi-image references. Ready-to-use REST inference API, best performance, no cold starts, affordable pricing.

Features

FireRed Image Edit is a powerful AI image editing model that combines elements from multiple reference images into a single cohesive output. Upload reference images of people, objects, or styles, then describe how to combine them — the model intelligently merges elements while maintaining natural composition and lighting.


Why Choose This?

  • Multi-image composition Combine elements from multiple reference images into one seamless result.

  • Natural language editing Describe your edit in plain text — reference images by Figure number for precise control.

  • Flexible sizing Specify custom output size, or leave blank to match the first image’s aspect ratio.

  • Intelligent blending Automatically adapts lighting, perspective, and style for realistic integration.

  • Prompt Enhancer Built-in tool to automatically improve your edit descriptions.


Parameters

ParameterRequiredDescription
promptYesText description of the desired edit (use “Figure 1”, “Figure 2” to reference images)
imagesYesReference images to combine (click ”+ Add Item” to add more)
sizeNoOutput size; if empty, matches the first image’s aspect ratio

How to Use

  1. Upload reference images — add all images containing elements you want to combine.
  2. Write your prompt — describe the edit using “Figure 1”, “Figure 2”, etc. to reference specific images.
  3. Set size (optional) — specify output dimensions, or leave blank to use first image’s ratio.
  4. Use Prompt Enhancer (optional) — click to automatically refine your description.
  5. Run — submit and download your edited image.

Best Use Cases

  • Virtual Try-On — Put a person in different outfits from reference photos.
  • Character Compositing — Combine character features with new environments or accessories.
  • Product Visualization — Show products on different models or in various settings.
  • Creative Compositing — Merge elements from multiple sources for unique imagery.
  • Marketing & Ads — Create customized visuals by combining brand assets.

Pro Tips

  • Use “Figure 1”, “Figure 2”, etc. in your prompt to reference images in upload order.
  • Clear, front-facing reference images produce the best element extraction.
  • The first image determines the default output aspect ratio when size is not specified.
  • Describe the scene context (location, lighting, mood) for more cohesive results.
  • For best results, use reference images with similar lighting conditions.

Notes

  • Both prompt and images are required fields.
  • Ensure uploaded image URLs are publicly accessible.
  • Output size defaults to first image’s aspect ratio if not specified.
