Seedream 4.5 is built for readable design, poster layouts, and high-resolution visuals
A Seedream image model focused on typography, designer-level composition, prompt adherence, high-resolution output, and strong visual quality.
Enhanced typography
Seedream 4.5 is tuned for sharper, more legible text inside images, making it useful for posters, logos, UI mockups, product cards, and marketing layouts where words need to survive the generation step.
Designer-level composition
The model handles complex poster-style layouts with clearer hierarchy across title, subtitle, body text, logos, product imagery, and background elements, so generated visuals feel closer to designed material than a raw image prompt.
Strong prompt adherence
Seedream 4.5 follows detailed descriptions for subject, layout, mood, and visual style more closely, which helps when you need a specific arrangement rather than a loosely related beautiful image.
High-resolution output
Seedream 4.5 is designed for high-resolution generation. The model supports custom width and height ranges in its provider spec; on Raphael AI, the entry keeps control simple with documented ratios and 2K / 4K quality presets.
Strong aesthetic quality
Seedream 4.5 performs well on visual-quality benchmarks such as MagicBench, and is a practical choice for polished marketing images, product visuals, posters, and high-impact creative assets.
