Black Forest Labs launches with FLUX.1, a 12B-parameter text-to-image family

FLUX.1 [pro] at a glance

FLUX.1 came in three variants: pro via API, dev with open weights for non-commercial use, and schnell under Apache 2.0. The company also announced a $31 million seed round led by Andreessen Horowitz.

What changed with FLUX.1 [pro]

Black Forest Labs announced itself on August 1, 2024, with the FLUX.1 text-to-image family, all scaled to 12B parameters. FLUX.1 [pro] was the top model, offered through the company's API and on Replicate and fal.ai. FLUX.1 [dev] was an open-weight, guidance-distilled model for non-commercial use, and FLUX.1 [schnell], the fastest, was released under Apache 2.0.

Weights for dev and schnell went to Hugging Face, with inference code on GitHub. The company also announced a $31 million seed round led by Andreessen Horowitz.

Why FLUX.1 [pro] matters for businesses

For businesses, FLUX.1 gave design and marketing tools a high-quality image engine that could be called by API or, for some variants, run in-house. The split licensing mattered: schnell could be used commercially, dev needed a separate agreement, and pro was pay-per-use.
