Multi-Reference Image Generation: The Workflow Game-Changer

Beyond Simple Text-to-Image

Standard AI image generators accept one prompt -> one image. Advanced models add one reference image for style transfer. Seedream 4.5 accepts up to 5 reference images and intelligently synthesizes them into a coherent output.

Use Case 1: E-Commerce Product Photography

Product photo on white background + lifestyle reference image = product naturally placed in scene. No Photoshop required:

{"model":"doubao-seedream-4.5",
 "prompt":"Natural lifestyle placement of the product",
 "reference_images":["https://cdn.example.com/product.jpg",
                     "https://cdn.example.com/lifestyle-room.jpg"],
 "n":4}

Use Case 2: Brand-Consistent Social Media

Style guide + product + setting = on-brand social posts, all programmatic:

{"model":"doubao-seedream-4.5",
 "prompt":"Summer sale announcement, beach theme",
 "reference_images":["https://brand.example.com/style-guide.jpg",
                     "https://brand.example.com/product-hero.jpg"]}

Use Case 3: Group Photo Composition

AI has historically struggled with group photos. Seedream 4.5 handles it by processing individual portraits and composing a natural group shot:

{"model":"doubao-seedream-4.5",
 "prompt":"Team photo in modern office, natural lighting",
 "reference_images":["person1.jpg","person2.jpg","person3.jpg"]}

Performance Notes

Multiple references add ~2-5 seconds to generation time per image
Best results with references of similar resolution (recommend 1024px+)
Works with both Seedream 4.5 ($0.034/image) and Seedream 4.0 ($0.027/image)
