Seedream 4.5
ByteDance's cinematic AI image model — production quality at an accessible price
Seedream 4.5 is ByteDance's image generation and editing model — built by the company behind TikTok and trained on one of the world's largest visual content libraries. It unifies image creation and editing in a single architecture, delivering cinematic lighting, strong character consistency, and professional text rendering. On Keyo Studio, Seedream 4.5 is one of the most affordable paths to production-ready images, starting at just 1 credit per generation.
What is Seedream 4.5?
Seedream 4.5 is ByteDance's fourth-generation image model, designed for professional creative workflows. It handles both text-to-image generation and image editing in a unified architecture — you can create from a prompt, then refine the result without switching tools. ByteDance trained it on an enormous volume of visual content and engagement data, giving it a strong sense of visual aesthetics and composition that stands out from competitors. It supports output resolutions up to 4K across multiple aspect ratios.
Multi-reference image composition
Seedream 4.5 accepts up to 10 reference images in a single generation request, enabling complex multi-source workflows. It accurately identifies subjects across references and preserves their details — depth, perspective, lighting, and identity — while compositing them into a new scene. This makes it a strong tool for product photography (swap backgrounds while keeping the product exact), character consistency across a series, and brand-asset workflows where visual identity must remain locked.
Cinematic lighting and photorealism
Built with a cinematic-first approach, Seedream 4.5 produces images with natural, film-quality lighting and rich detail. It understands spatial relationships and renders complex scenes with accurate depth and perspective. Whether you're creating product visuals, lifestyle imagery, or concept art, the output has a polished, production-ready look that requires minimal post-processing.
Professional text rendering
Like other top-tier models, Seedream 4.5 handles text rendering with precision — generating accurate spelling, supporting diverse font styles, and integrating text naturally into compositions. Labels, fine print, and intricate typographic elements remain clear and legible, making it suitable for packaging mockups, social media graphics, marketing materials, and any design that includes readable text.
Best use cases
Seedream 4.5 is ideal for creators who need consistent, production-quality images at scale: product photography and lifestyle shots, marketing banners and social content, storyboards and character-consistent series, brand assets with locked visual identity, and any workflow where multiple reference images need to blend into a cohesive result. Its accessible pricing makes it practical for high-volume production where cost matters as much as quality.
