Seedream 4.5 — Bring Commercial Design Back to Efficiency
ByteDance’s next-generation multimodal AI image model, built for e-commerce, advertising, brand design and content creators. Fast, consistent, and production-ready.
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.
Model comparison (2025 practical overview)

Seedream 4.5 = commercial design production engine; Midjourney = artistic illustration; DALL·E = narrative/creative generation; Flux = lightweight experiments.
How to use (official recommended flow)
- Provide input: text prompt (Chinese works) and/or reference images (product photos, portraits, sketches).
- Choose mode/style: advertising, commercial photography, poster layout, product shot, or series-consistency mode.
- Generate images: single image 30–60s; multiple variations in parallel with high success rate.
- Refine scene: change background, adjust lighting/angle/color, add or format text.
- 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.
