Frequently Asked Questions

Seedream 4.5 is ByteDance's flagship image generation model that combines high-fidelity 2K output (upscalable to 4K) with exceptional text rendering capabilities. Its standout feature is the unified generation and editing workflow, allowing seamless inpainting and outpainting without switching tools. Ranked #10 on LM Arena with a score of 1147, it competes directly with Google's Nano Banana while offering superior typography handling and multi-reference image support.
Seedream 4.5 achieves industry-leading text rendering accuracy at over 99%, solving one of the most persistent challenges in AI image generation.
