WaveSpeed High-quality image generation from ByteDance
Seedream 4.0 is an image generation model developed by ByteDance, designed to produce images from text prompts and source image inputs. It supports a context window of 10,000 tokens and accepts image URL arrays alongside numerical parameters, enabling flexible control over generation behavior. The model is part of ByteDance's Seedream series and is available through MindStudio's model catalog.
Seedream 4.0 is best suited for workflows that require image generation guided by reference images, making it useful for tasks like style transfer, image variation, and visually consistent content creation. Its support for source image inputs distinguishes it from purely text-to-image pipelines, allowing users to anchor outputs to existing visual references. Developers can integrate it into MindStudio applications without managing separate API keys.
