Key Features of Seedream 4.0

Unified Generation and Editing

Seedream 4.0 unifies text-to-image creation and precise image editing in a single workflow, eliminating tool-switching and preserving visual consistency. With natural prompt control, you can add, remove, or replace objects while maintaining composition, lighting, and style—accelerating concepting, iteration, and production-quality results.

4K Speed and Quality in Seedream 4.0

Deliver crisp, production-ready visuals up to 4096 px with fast inference that keeps creative momentum high. Whether you’re building hero images or detailed UI assets, Seedream 4.0 balances resolution, fidelity, and throughput so teams can prototype quickly and ship polished visuals on time.

Multi-Reference and Batch Workflows

Maintain character, product, or brand consistency using multiple reference images while generating cohesive sets in one run. Seedream 4.0 supports multi-reference alignment and batch outputs, enabling storyboard sequences, A/B style explorations, and catalog variations with controllable structure, palette, and camera cues.

Natural-Language, Single-Sentence Edits

Precisely direct changes with plain language—“remove the logo,” “replace the cup with a mug,” or “move the light to the left.” Seedream 4.0 interprets intent and applies localized edits without degrading the rest of the image, making revisions faster and reducing manual post-processing.

Seedream 4.0 Style Transfer

Apply flexible aesthetics—from watercolor, pencil, and cel-shaded to cyberpunk neon or architectural linework—while preserving subject identity. Seedream 4.0 maps styles to composition and materials intelligently, enabling explorations that feel intentional rather than filter-like, ideal for branding, mood boards, and visual R&D.

Knowledge-Driven, Accurate Generation

Create diagrams, charts, timelines, and annotated scenes that remain readable and on-brief. Seedream 4.0 leverages strong prompt understanding to place labels, arrows, and legends correctly. With reliable spatial reasoning, Seedream 4.0 produces instructive assets for marketing, education, and product documentation with minimal cleanup.

How to Use Seedream 4.0?

Step 1: Set Up Your Prompt and Inputs

In Seedream 4.0, define a clear prompt, choose size (1K/2K/4K or custom width/height), select aspect_ratio or match_input_image, decide sequential_image_generation (disabled/auto), set max_images, and add image_input references for style or identity. Enable enhance_prompt when you need extra fidelity before Seedream 4.0 renders the first pass.

Step 2: Generate and Refine with Natural-Language Edits

Run the first generation, then refine in Seedream 4.0 using single-sentence edits like “replace the logo” or “move the light left.” Adjust guidance and settings, switch styles, or increase resolution. Use multi-reference to keep subjects consistent and iterate quickly until Seedream 4.0 matches your creative intent.

Step 3: Batch, Compare, and Export

Use batch workflows in Seedream 4.0 to explore variations across poses, palettes, or camera angles. Leverage max_images in auto mode to storyboard scenes, then export 4K outputs via returned URIs. Organize versions, pick winners, and hand off production-ready assets with minimal retouching.
