Z-Image Turbo is a model for volume work and prompt testing: text-to-image only, no resolution choice, at a fraction of FLUX.2 [pro]'s price. Pick FLUX.2 [pro] when the image is going to be published, when you need 2K, or when you want to build a scene from several reference photos. In my tests FLUX.2 [pro] produced clearly better images.
Key differences

- In-image text. Z-Image lists English and Chinese text rendering. In my tests both models got Polish diacritics wrong.

When to pick Z-Image Turbo

Cost in practice
FLUX.2 [pro] at 1K costs about 3.4 times as much per image as Z-Image Turbo, and at 2K about 4.8 times as much. At 100 images that gap shows in your balance; at a handful it hardly matters. Neither model charges for references (Z-Image takes none). Rates: $0.02 per image and from $0.0688 per image (1K); all models on /pricing.
My tests on promptowy.com (Polish blog): in the image ranking FLUX.2 [pro] scored 7.6/10 and Z-Image Turbo (run locally, same model) 5.7/10. Z-Image misspelled the accented Polish sign and drew in the masthead of a magazine whose style it was only meant to imitate; FLUX.2 [pro] also dropped accents on the sign. In an earlier 32-model test Z-Image correctly spelled a made-up word (no diacritics) on a sign, and FLUX.2 [pro] was among the photorealism leaders.
