Seedream 4.5 is ByteDance's premium image generation and editing model released in December 2025, delivering all-round improvements over Seedream 4.0 in subject identification accuracy, reference image fidelity, and typographic rendering — including dense small-text and multi-line layouts. It supports up to 14 reference images per request, produces outputs at up to 4K resolution, and ranks among the top models on the LM Arena global image generation leaderboard. Generation takes 8 to 14 seconds depending on complexity, prioritizing output quality over speed for final production assets such as brand campaigns, product photography, and client-facing creative work.
