Introduction
WaveSpeedAI has officially integrated Seedream4.5 by ByteDance, bringing one of the most advanced multimodal image-generation models to its platform. ByteDance’s seedream series has long been known for cinematic visuals and strong creative capabilities, but Seedream4.5 stands out as a major technical advancement, delivering sharper detail, higher stability, and more accurate interpretation of complex prompts.

With this update, WaveSpeedAI users gain access to a generation of experience that is more reliable, more visually coherent, and more aligned with industry-level creative standards.
