Flux (Black Forest Labs)
Photorealistic AI image generation
By Black Forest Labs
Our verdict
Flux is our primary image generation tool for client work. The photorealistic quality, text rendering, and prompt adherence are best-in-class. We use Flux Pro via fal.ai for product photography generation, OOH artwork, and source images that feed into our video pipeline. Flux Schnell (the open-source tier) is excellent for exploration. The lack of a polished web UI is irrelevant for production use where we are calling the API directly.
