Batch generation

One-line Chinese prompts often produce production-ready visuals — reference images recommended for identity locking and series consistency.

Core advantages

Exceptional consistency

Identity embedding and multi-image chain reasoning keep a person or product constant across dozens of outputs — no style drift.

Designer-grade layout & typography

Built-in layout priors and typography rules keep small text legible and compositions balanced — deliver client-ready posters with less editing.

Photorealistic lighting & materials

Trained on commercial photography & advertising imagery; supports cinema-grade lighting, correct perspective and realistic materials in 4K output.

High-efficiency batch production

One-click background/scene/light swaps and batch rendering allow 10+ consistent variations in minutes — perfect for detail pages and campaign series.

Reference-driven control

A multimodal visual encoder recognizes product structure, facial features and brand tone; fuse multiple references to keep color and style consistent across scenes.

Fast & approachable

Short prompts (even in Chinese) work well. No 'magic prompt' required — the model is optimized for production workflows.

Technical upgrades (4.5 vs 4.0)

Cleaner training data

Design- and photography-focused datasets produce a premium, "high-end" output.

Identity embedding

Improved subject consistency — faces don't collapse, products don't drift.

Layout priors

Professional typography and stable visual hierarchy out of the box.

Enhanced scene & lighting

More cinematic feel and accurate spatial depth.

Where it fits

Seedream 4.5 excels where consistency, layout and production speed matter most.

E-commerce

Generate hero images, product detail pages, lifestyle scenes and promotional creatives. Swap backgrounds, props and lighting for electronics, beauty, baby products, home, small appliances and FMCG.

Advertising & Brand Visuals

Produce KV visuals, campaign posters, packaging mockups and UI compositions with layout-ready text and stable composition—less guesswork, more deliverables.

Content Creators

Quick thumbnails and covers for TikTok/Douyin, Xiaohongshu and WeChat. Emotion-driven imagery and attention-grabbing cover art delivered fast.

Interior / Spatial Visualization

Room renderings, layout proposals and lighting simulations with reliable perspective and depth logic.

How to use (official recommended flow)

  1. Provide input: text prompt (Chinese works) and/or reference images (product photos, portraits, sketches).
  2. Choose mode/style: advertising, commercial photography, poster layout, product shot, or series-consistency mode.
  3. Generate images: single image 30–60s; multiple variations in parallel with high success rate.
  4. Refine scene: change background, adjust lighting/angle/color, add or format text.
  5. Finalize: export to Photoshop/Figma/Premiere for final polishing.

Tips: keep prompts concise, use reference images to lock identity/style, reuse composition keywords (eg. "clean composition, centered layout"), and generate multiple versions to pick the best.

Typical workflows by role

Designers

Produce poster drafts, KVs and hero visuals in minutes—save ~60% of exploratory time. Batch-produce variations for Photoshop refinement.

E-commerce managers

Upload smartphone product photos and receive multiple scene variants, banners and detail images. Generate 20+ headline variants for A/B tests.

Ad agencies

Create moodboards and KV proposals aligned with brand tone and layout expectations. Previsualize cinematic scenes to improve pitch success.

Why layouts look like real designers’ work

  • Training emphasizes design artifacts: headline/subhead balance, whitespace and hierarchy.
  • Built-in layout priors (centered composition, rule-of-thirds, splits and headline blocks) are applied automatically.
  • Robust text rendering keeps fonts legible and free from visual collisions.
  • Style templates favor high-end commercial aesthetics, so outputs read as premium.

Community feedback

“Higher consistency; multi-image editing and typography have clearly improved.” — community user

“Great for e-commerce and ads: keeps style and subject stable across batches.”

Common notes: occasional paid-download watermark, strict NSFW filtering, and less reliability on extremely complex human poses.

FAQ

Is it allowed for commercial use?
Paid subscriptions typically grant commercial rights so generated assets can be used in e-commerce, ads and brand materials.
How good is Chinese text layout?
Chinese typography has been specifically optimized—posters, ads and packaging render clearly and reliably.
How fast and reliable is generation?
Single-image generation ~30–60 seconds; batch workflows complete in minutes with low failure rates—designed for high-volume production.
How is consistency achieved?
Upload a reference image, use series-consistency mode and consistent composition keywords—identity embedding keeps subject features aligned across scenes.
What is it not suitable for?
Ultra-highly realistic portrait close-ups, complex multi-person dynamics, avant-garde artistic styles, explicit NSFW content, and extreme experimental compositions.
