Seedream v4 vs Flux Pro 1.1
The flagship-versus-flagship question, and it splits cleanly by subject. Seedream v4 wins photography: skin keeps its texture instead of turning to plastic, and light falls the way a real source falls. Flux Pro 1.1 wins constructed imagery: graphic composition, illustration, product renders, anything with a designed rather than observed look.
Seedream is also the cheaper of the two and reaches a larger maximum dimension, up to 4,096 pixels on a side against Flux Pro's 2,048. If your work is portrait or product photography, that combination makes Seedream the straightforward pick. If it is illustration or concept art, the Flux look is the one you are after and the price gap is what it costs.
Choose Seedream v4 if
- Portraits, people, skin
- Natural light and photographic realism
- You need dimensions beyond 2048px
Choose Flux Pro 1.1 if
- Illustration, concept art, graphic composition
- A designed look rather than an observed one
- Fine detail across a complex constructed scene
