Flux (Black Forest Labs)
Open-source image generation model among the most accurate on the market, accessible via API or locally
Overview
Flux is the image generation model family from Black Forest Labs (founded by researchers from Stable Diffusion). Open-weight versions (Flux.1 Schnell and Dev) are freely downloadable for local use, while Flux.1 Pro and FLUX.2 Pro are accessible via paid API at roughly $0.02 to $0.06 per image depending on resolution.
Flux is recognized for exceptional photographic rendering, precision on text within images, and ability to follow complex prompts. It integrates into dozens of third-party tools (Krea, ComfyUI, Replicate) but requires technical skill to exploit directly.
Our verdict
Flux is built for developers and technical teams who want the best image generation engine embedded in their own product or pipeline. For an SME without developers, access it via Krea AI or Recraft instead of direct integration. It's not a turnkey tool.
