State-of-the-art prompt recipes for Black Forest Labs Flux.1 (Dev & Schnell). Renowned for exceptional text rendering, anatomical accuracy, and photorealistic skin rendering with lower CFG scale requirements.
Flux follows natural descriptive text without requiring heavy tag repetition.
Keep CFG scale between 2.5 and 4.0 in Flux Dev to prevent burned colors and oversaturation.
Specify exact typography in quotation marks (e.g. "a vintage diner with glowing sign reading 'OPEN 24/7'").
Flux uses flow matching architecture that converges cleanly at lower guidance scales (2.5 - 4.0), whereas higher CFG values cause artifacting and chromatic distortion.
