FLUX (Black Forest Labs)

About FLUX (Black Forest Labs)

Black Forest Labs is a Freiburg, Germany-based AI company that develops the FLUX family of image generation models. Founded in 2024 by former key researchers from Stability AI, the company has quickly established FLUX as one of the most capable open and commercial image generation model families available, competing directly with Midjourney, DALL-E 3, and Stable Diffusion on quality benchmarks. The FLUX model family includes FLUX.1 [schnell] (fast, Apache 2.0 open source), FLUX.1 [dev] (open weights for non-commercial use), and FLUX.1 [pro] and FLUX.1.1 [pro] (commercial API-only). The commercial models are accessible through Black Forest Labs' own API (api.bfl.ml), as well as via third-party platforms including fal.ai, Replicate, and Together AI. Organisations building pipelines should be aware that routing via US-based API partners (fal.ai, Replicate) means data transits US infrastructure even if the underlying model originates in Germany. For compliance-focused European organisations, the most sovereignty-friendly approach is to access FLUX directly via the Black Forest Labs API or to self-host the open-weight FLUX.1 [schnell] or [dev] variants on EU cloud infrastructure. Self-hosting on EU providers such as Hetzner, OVHcloud, or AWS Frankfurt gives full control over data residency, training, and retention. The open-source [schnell] variant carries no usage restrictions beyond the Apache 2.0 licence. Black Forest Labs is incorporated and headquartered in Germany, meaning the primary legal jurisdiction for the direct API is EU/German law. The company does not publicly claim to train on customer-submitted prompts or images for the commercial API, though buyers should request explicit DPA terms for regulated deployments. As a seed/early-stage company, formal certifications such as ISO 27001 or SOC 2 are not yet in place as of 2025, which is a consideration for enterprise procurement. Pricing for the commercial API is usage-based: FLUX.1.1 [pro] costs approximately $0.04 per image, FLUX.1 [pro] $0.05, and FLUX.1 [dev] $0.025 per image step via the official API. No subscription plans exist at the platform level — costs scale with generation volume. For EU businesses seeking a domestically developed, high-quality image generation API, FLUX represents the strongest sovereignty option currently available in the market.
