Overview
FLUX.1 spans Dev, Krea, Schnell, and SRPO variants with text-to-image, image-to-image, and Redux style endpoints. FLUX.1 [dev] is a 12-billion-parameter model generating high-fidelity images from natural language with consistent multi-generation results. Its image-to-image endpoint transforms existing images while preserving composition, supporting style transfers across common formats. Krea, described as a Black Forest Labs collaboration with Krea AI, tunes the 12B flow transformer for aesthetic quality with 28-step default inference and up to 4-megapixel output.
