FLUX.2 [flex]
FLUX.2 Flex is a hosted image model focused on text rendering and small visual details. It supports generation and editing while exposing sampling steps and guidance.
Model details
The API exposes both guidance and inference steps, with defaults of 5 and 50. Prompt upsampling is enabled by default. These controls allow the caller to change the sampling process instead of using only a fixed service recipe.FLUX.2 [flex] official documentation
Practical use
Practical guidance. Use Flex when typography or fine visual detail needs deliberate tuning. Change one control at a time and inspect exact spelling at the final output size. A visually convincing poster can still contain an incorrect character or an unreadable line.
