Seedream 4.0: 4K-native AI image generation from ByteDance
Picsart's AI Image Generator integrates Seedream 4.0, the ByteDance Seed image model that brought native 4K generation, photorealistic detail, and strong prompt fidelity to the AI image space. Built for creators who need clean, high-resolution output from a single prompt, Seedream 4.0 powers product shots, social visuals, and design-ready imagery — all available alongside Seedream 4.5 on Picsart.

What is Seedream 4.0?
Seedream 4.0 is ByteDance Seed's text-to-image model and the first release in the Seedream family. It generates native 4K images directly from natural-language prompts, with strong prompt fidelity, photorealistic detail, and reliable composition. Seedream 4.0 set the foundation for the Seedream family — fast iteration, production-ready output, and a workflow built for creators who ship visuals on a deadline.
