What Flux2 is for
Flux2 from Black Forest Labs is a text-to-image model. You describe the frame and it returns a still image in about 10 seconds, billed at $0.03 per image. This page groups 11 modes (Text to Image, Image Editing, Text to Image, Image Editing, Text To Image (Turbo), Text to Image (Flash), Image Editing (Flash), Image Editing (Turbo), Text to Image LoRA, Outpaint, and Image Editing LoRA) so you are not hunting separate URLs for the same family.
Flux2 is billed in Knowlify credits at the compute cost ($0.03 per image). A typical run is about 10 seconds. Published rate: Your request will cost $0.03 for the first megapixel of output, plus $0.015 per extra megapixel of input and output, rounded up to the nearest megapixel. For example, a 1024x1024 image will cost $0.03, and a 1920x1080 image will cost $0.045 ($0.03 for first megapixel + $0.015 for the second megapixel). Similarly, a 512x512 output will cost $0.03 ($0.03 for 0.25 megapixels, rounded to 1 megapixel)
