The following comparisons are conducted by our Ima Studio internal team. We try to understand the capability of Seedream 4.0 and how much it is different from the other products, and we saw many exciting features that Seedream 4.0 supports while others are not good at.

What Seedream 4.0 excels at

1. Higher Resolution Outputs
   • While older versions (like Seedream 3.0) and some competitors output at 2K resolution, Seedream 4.0 supports 4K output for its image generation.
2. Continuity and Variation in Images (Single Prompt → Multiple Outputs)
   • From a single prompt + reference image, it can produce multiple high-resolution variations. This includes creative changes while maintaining consistency.
   • It supports “continuation/rewriting” — i.e. using one image to generate sequels or variants.
3. More Precise and Controllable Multimodal Generation
   • Seedream 4.0 lets the generated images act like “keyframes” (i.e. reference points) which improves control over how the model continues or varies image content.
   • Better at taking reference images + prompts and manipulating styles, poses, angles, etc., with more consistency.
4. Improved Aesthetic Quality and Detail
   • The images are more vivid, with higher fidelity in details like texture, lighting, facial features, etc. Comparisons suggest an aesthetic advantage over previous models.
