Which should you choose?
Choose FLUX.2 Flex if
- your work is mostly: general image generation
Choose Seedream 5.0 Pro if
- price per image is the deciding factor (15 vs 16 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
Still unsure? Run one identical prompt through both. In Vyndexo that is two generations from the same screen and the same credit balance.
