• Reference-Based Transparent Assets: Use image references to create standalone elements with native transparency for compositing and layout work.
• Multiple Reference Images: Combine subject, product, and setting references with instructions for their relative scale, perspective, and lighting in the final composition.
• Natural Visual Detail: Refine photographic imagery with attention to materials, skin textures, and lighting.

• Flexible Output Settings: Choose a resolution up to 2K, supported output proportions, and an automatic, transparent, or opaque background.

How to Use Seedream 5.5 Edit API on Best Image AI

• Input: Provide reference image URLs and a natural-language editing prompt. Identify the role of each reference, the precise object or region to change, and the details to preserve.
• Text Changes: Specify the original wording and its exact replacement, including punctuation and line breaks. Describe the position, type style, and spacing to retain.
• Output Settings: Select a supported aspect ratio and resolution for each request, and choose the background treatment needed for the final asset.
• Output: Each completed task returns one PNG image through Best Image AI's image-task workflow. Transparent results also use PNG.
• Successive Edits: Submit the previous output as an image input with your next instruction. Make each request self-contained: identify the current object, describe its target state, and repeat key preservation requirements instead of relying on earlier conversation history.
• Billing: The charge includes the output image at the selected resolution and every supplied reference image, starting with the first. Repeated image URLs are charged as separate input entries.
