Seedream 5.5 Edit API for Stable Multi-Turn Editing and Transparent Assets

Seedream 5.5 Edit API on Flaq AI delivers stable multi-turn image editing, precise local changes, and transparent asset creation. Refine clothing, accessories, product details, and scene elements across successive edits while preserving the detail, color, and composition of unedited regions. Combine reference images and natural-language instructions to build production visuals through a single API workflow.

Key Features of Seedream 5.5 Edit API

Stable Multi-Turn Editing: Maintain visual consistency across repeated edits, preserving detail and color in unedited regions as you progressively refine the same image.
Precise Local Changes: Replace an individual accessory, recolor a product, or adjust a facial detail while retaining surrounding textures, other objects, and the overall composition.
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.
Text Replacement in Images: Update a heading, label, or displayed number while preserving the surrounding layout and typography.
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 Flaq 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 Flaq 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.

Best Use Cases for Seedream 5.5 Edit API Integration

Product Creative Revisions: Recolor a garment or replace an individual ring while retaining the product shape, camera angle, and surrounding details.
Portrait and Fashion Iteration: Change outfits, accessories, and settings across successive edits while maintaining the subject's identity and appearance.
Reusable Transparent Graphics: Prepare reference-based subjects and decorative elements for campaign layouts and presentation slides.
Poster and Label Updates: Replace a campaign headline, product label, or information display without redesigning the whole image. Supply the final wording when preparing another language version.
Campaign Adaptation: Refine an approved concept through successive changes to props, accessories, and scene details while keeping the rest of the design consistent.
Reference-Guided Design: Build product or character scenes from multiple references, specifying how subject scale, shadows, and perspective should fit together.

Note Use reference images you have permission to edit, and ensure images and prompts comply with ByteDance's safety guidelines. If a request fails, check the inputs and returned error before retrying.
