What is Flux?

Flux is a family of image generation models from Black Forest Labs (founded by ex-Stability AI researchers). It’s renowned for producing the most photorealistic AI images available, particularly excelling at portraits, skin textures, and product photography.

The Flux family includes multiple models: Flux Schnell (fast, open), Flux Dev (development, open), Flux Pro (premium, API), and Flux 2 (latest generation). Flux gained rapid adoption in 2024-2025 by offering Midjourney-competitive quality with more accessible pricing and local running options.

What makes Flux special is photorealism. When you need images that look like actual photographs — realistic skin, proper lighting physics, convincing depth of field — Flux delivers.
