Frequently asked questions
Black Forest Labs FAQs
What is FLUX?
FLUX is a family of image generation models from Black Forest Labs. FLUX.1 Dev and Schnell are open-weight; FLUX 1.1 Pro and Pro Ultra are commercial API models offering the highest quality.
How does FLUX compare to Stable Diffusion?
FLUX consistently outperforms Stable Diffusion 3.5 on image quality benchmarks, particularly for photorealism and prompt adherence. FLUX Schnell is also significantly faster than SD 3.5.
Stability AI FAQs
What is Stable Diffusion?
Stable Diffusion is an open-weight text-to-image model developed by Stability AI. It can be run locally or accessed via the Stability AI API, and has spawned a large ecosystem of fine-tuned variants.
How does Stability AI compare to DALL-E 3?
DALL-E 3 generally produces more photorealistic and instruction-following images out of the box. Stable Diffusion offers more flexibility through open weights, fine-tuning, and self-hosting.
