Which should you choose?
Choose FLUX.2 Pro if
- price per image is the deciding factor (10 vs 13 credits)
- the final render is what matters and you accept a higher price per generation
- your typical job is final images where detail matters most
Choose Seedream 4.5 if
- you need 4K output
- your typical job is general image generation up to 4K
Still unsure? Run one identical prompt through both. In Vyndexo that is two generations from the same screen and the same credit balance.
