How to decide
My image ranking on the Polish blog used the same five prompts for each model: Nano Banana Pro scored 9.0/10 and FLUX.2 [pro] 7.6/10. Without text FLUX.2 held up well, with 8.5 for the illustration, the portrait and the food shot, and it was quicker (13 s against 18.6 s, measured with another provider). The Polish sign pulled it down to 5/10, and a separate typography test found at least four errors in three graphics. So: text in the image - Nano Banana Pro; pure photo - FLUX.2 [pro].

Questions
I like FLUX.2 but need lettering. What can I do?
Leave empty space in the layout and add the text yourself in an editor afterward. That avoids broken accents entirely.
Can FLUX get to 4K?
Not with FLUX.2 [pro], which tops out at 2K. For bigger files, up to 4 MP, look at FLUX.2 [max].
Does a failed image cost anything?
No. If a generation fails or is rejected, the held amount goes back to your balance in full.
