Flux AI - Free AI Image Generator

Black Forest Labs' image generation family — from fast drafts to professional-grade output

Flux AI is a family of image generation models from Black Forest Labs (BFL), the German AI company founded by the original creators of Stable Diffusion. On Genkee AI, six Flux variants are available — each optimized for different workflows. Flux Schnell (1 credit, 3-15s) is the fastest image model on the platform, ideal for rapid idea exploration. Flux Dev (1 credit) adds image-to-image support. Flux 1.1 Pro (2 credits) is the flagship with the best prompt adherence and detail. Flux 1.1 Pro Ultra (2 credits) generates at 4K resolution (2048×2048) — the highest resolution image output on Genkee AI. Flux Kontext Pro and Kontext Max add image editing capabilities, letting you modify specific parts of an existing image with text instructions. Flux models are known for their clean, well-composed outputs and exceptionally strong text rendering in images — if you need readable text, logos, or typography inside your generated image, Flux is the best choice.
