Seedream 4.5 — Cinematic 4K Portrait With Layered Lighting
Seedream 4.5 generates native 4K images with accurate lighting, layered shadows, and convincing material rendering — realistic skin, fine fabric, metal, and glass. Complex lighting setups like backlighting and multi-source illumination are handled naturally, producing film-quality results rather than typical AI art.
Seedream 4.5 — Multi-Reference Style Fusion
Seedream 4.5 accepts up to 14 reference images in a single generation — an industry-leading input capacity. Combine style references, character concepts, color palettes, and scene elements and the model intelligently fuses them into a cohesive, high-quality output.
Before
AfterSeedream 4.5 — Consistency (Reference → Output)
Generate a batch of up to 15 images and Seedream 4.5 locks onto character identity — face shape, hairstyle, body proportions — and maintains these attributes across every image. Props stay stable, color palettes stay cohesive, and lighting conditions remain consistent. No identity drift, no facial glitches, no pose mismatches.
Seedream 4.5 — Branded Poster With Accurate Typography
Seedream 4.5 renders both English and Chinese text accurately within images — stable text blocks, correct alignment, and legible typography at any size. Ideal for posters, packaging, branded content, UI mockups, and multilingual signage where text quality is non-negotiable.
Seedream 4.5 — Complex Prompt Adherence
Seedream 4.5 interprets complex, multi-layered prompts with high accuracy — handling spatial relationships, artistic terminology, abstract concepts, and nuanced creative briefs. Describe a scene with multiple subjects, specific lighting conditions, and compositional requirements and the model delivers what you described, not an approximation.
