FLUX.1 is a family of image generation models from Black Forest Labs (the team behind Stable Diffusion) that sets new quality benchmarks for prompt adherence, human anatomy accuracy, and photorealism. The models are available in three variants: FLUX.1 Pro (highest quality, API-only), FLUX.1 Dev (open-weight for research), and FLUX.1 Schnell (fastest, permissive Apache license). AI image enthusiasts, researchers, and developers building generation pipelines use FLUX.1 for its superior prompt following and anatomically correct human generation compared to SDXL. FLUX.1 Dev can be self-hosted on consumer GPUs via Comfy UI, making it accessible to the open-source community. FLUX.1's release in late 2024 significantly shifted the image generation landscape, with many Midjourney and SDXL users migrating for its prompt accuracy and hand/face rendering quality. It is now available through most major image generation platforms and APIs.

What the community says

The image generation community on Reddit r/StableDiffusion reacted to FLUX.1 as a major step forward, with widespread reporting of better hand generation, face accuracy, and prompt following than SDXL. Seen as the new open-source baseline to beat. Based on community discussions from Reddit.
