Introducing ByteDance Seedream 4.5 Edit Sequential: Multi-Image Editing with Unbreakable Character Consistency

The challenge of maintaining consistent character identity across multiple images has long been one of AI’s most frustrating limitations. Whether you’re building a product catalog, creating a marketing campaign, or developing character designs, the inability to preserve visual continuity between images has forced creative teams into tedious manual workflows. That changes today with the arrival of ByteDance Seedream 4.5 Edit Sequential on WaveSpeedAI.

This specialized multi-image editing model represents a significant leap forward in batch image processing, automatically tracking and preserving subject identity across entire series of images while applying controlled, consistent edits to every output.

What is Seedream 4.5 Edit Sequential?

Seedream 4.5 Edit Sequential is ByteDance’s purpose-built solution for applying the same transformation across multiple images while maintaining rock-solid identity preservation. Unlike traditional image editing tools that process each image in isolation, this model intelligently detects and locks onto your main subject—whether a person, product, or character—and ensures that facial structure, proportions, and distinctive features remain stable across every generated output.

The model builds on the foundation of Seedream 4.5’s industry-leading photorealism and material rendering while adding a specialized sequential processing pipeline. When you provide a set of source images containing the same subject, the model analyzes and tracks that subject throughout the series, then applies your requested edits with remarkable consistency.

What sets this apart from competitors like FLUX Kontext or Qwen Image Edit is its specialized architecture for batch operations. While those models excel at single-image editing tasks, Seedream 4.5 Edit Sequential is engineered from the ground up for multi-image workflows where continuity is non-negotiable.

Key Features

• Multi-image subject tracking: Automatically detects and locks onto the primary subject across all input images, treating them as the same person or object throughout the editing process

• Character consistency lock: Preserves facial structure, body proportions, hairstyles, and overall visual identity across every edited output—even with different angles, outfits, and lighting conditions

• High reference fidelity: Maintains lighting consistency, color balance, and key visual details from your source images while implementing the requested changes

• Controlled, repeatable edits: A single prompt drives consistent transformation across your entire batch, eliminating the variation that plagues single-image workflows

• 4K-ready resolution: Supports output sizes up to 4096×4096 pixels, delivering print-quality results suitable for commercial publication

• Production-grade quality: Produces sharp edges, low artifacts, and stable composition that meet professional creative standards

Real-World Use Cases

E-commerce Catalog Production

For online retailers managing hundreds or thousands of product SKUs, Seedream 4.5 Edit Sequential transforms the catalog update process. Upload your product photography series, describe the seasonal change you need—“add winter holiday styling with snow accents and warm lighting”—and receive a complete, visually cohesive set ready for publication. Background replacements, style transfers, and seasonal updates that once required hours of manual work now happen in minutes.

Brand Campaign Development

Marketing teams can generate campaign visuals where the same model, mascot, or hero product appears across social posts, ad sets, landing pages, and thumbnails with guaranteed consistency. When your brand relies on recognizable characters or spokespersons, maintaining their exact appearance across dozens of touchpoints becomes effortless.

Character Design and Storyboarding

Game developers, comic creators, and animation studios can dramatically accelerate their character asset workflows. Generate consistent character designs across multiple poses, outfits, and environments without the identity drift that typically requires extensive manual correction. Build complete character sheets or storyboard sequences where every frame maintains the established look.

Product Line Variations

When launching product variants—different colors, configurations, or seasonal editions—this model ensures every variation looks like it belongs to the same family. The subtle visual cues that communicate product coherence are preserved automatically, from material textures to lighting angles to compositional balance.

Getting Started on WaveSpeedAI

Using Seedream 4.5 Edit Sequential on WaveSpeedAI is straightforward:

1. Upload your source images — Provide the images you want to edit, ensuring they contain the same main subject or product across the series

2. Set your max_images parameter — Specify how many edited outputs you need from your input set (important: include this count in your prompt as well)

3. Write your edit prompt — Describe the shared transformation you want applied globally, for example: “Change outfit to a black suit, add soft studio lighting, keep poses and background consistent”

4. Choose your resolution — Select target dimensions up to 4096×4096 for maximum detail

5. Submit and review — The model processes your batch and delivers your consistent series

Pro tip: Put your cleanest, clearest reference image first in the sequence—the model relies on it most heavily for establishing identity. Use clear, global instructions rather than per-image directions for best results.

At just $0.04 per output image, producing an 8-image series costs only $0.32, making professional-grade batch editing accessible for projects of any scale.
