What is Flux?

Black Forest Labs' open-source image generation model known for photorealistic outputs and text rendering capabilities.

Flux is an open-source AI image generation model by Black Forest Labs that produces photorealistic outputs with industry-leading prompt adherence and in-image text rendering, available for free via self-hosted open weights or approximately $0.003–$0.05 per image through paid API tiers, making it a top choice in the text-to-image generation category for developers, creative agencies, and AI engineers.

Developed by Black Forest Labs—founded in 2024 by the original creators of Stable Diffusion—Flux represents the next generation of open-source AI image generation. Released in August 2024, Flux quickly gained recognition for producing exceptionally high-quality, photorealistic images that rival or exceed proprietary models like DALL-E 3 and Midjourney v6. What sets Flux apart is its combination of open-source accessibility and professional-grade output quality, offering creators a powerful alternative that can be self-hosted locally or accessed through multiple API platforms without the restrictions of closed commercial systems.
