TL;DR
Compare Seedream v5.0 and Seedream v4.5 for image generation and reference-image editing.
Two generations, both with edit support
Seedream v5.0 and v4.5 are both active in KrafLayer, and both include reference-image editing alongside standard text-to-image generation.
v5.0 is the current generation. v4.5 remains available as a tested alternative with a slightly different output character.
When to choose Seedream
- Use Seedream when you want broad aspect ratio support and higher-resolution image output options.
- Use the edit variants when you want to keep the original identity while changing style or details.
- Compare Seedream against Nano Banana when you want a high-quality image lane at a different cost profile.
