innFactory AI Consulting from Rosenheim, Germany advises enterprises across the DACH region (Germany, Austria, Switzerland) on GDPR-compliant use of image generation models. FLUX by Black Forest Labs is the leading European AI alternative for image generation - developed in Freiburg im Breisgau, Germany by the founders of Stable Diffusion, with EU data residency and highest quality standards.
German AI Innovation from Freiburg im Breisgau
Black Forest Labs, headquartered in Freiburg im Breisgau, Germany, stands for European AI sovereignty. Founded by the creators behind Stable Diffusion, the company combines cutting-edge research with the strategic advantage of being a German entity. For enterprises in the DACH region, this means a world-class image generation model from a German provider that enables complete data sovereignty.
With the FLUX.2 generation (introduced in November 2025), Black Forest Labs sets new benchmarks in image generation. The family includes four variants - [pro], [flex], [dev] and [klein] (added January 2026) - covering the full spectrum from cloud API to self-hosting and on-device generation.
FLUX.2 [pro] - The New Flagship
The flagship FLUX.2 [pro] delivers photorealistic images up to 4 megapixels, based on a novel latent flow matching architecture combining a 24-billion parameter Mistral-3 vision-language model with a 32-billion parameter rectified flow transformer:
- 32k token context window for detailed, multi-part prompts
- Multi-reference: Up to 8-10 reference images simultaneously for consistent characters, products, and styles
- Clean typography: Precise text rendering, even at small sizes
- Photorealism: Realistic lighting and physics, eliminating the “AI look”
FLUX.2 [klein] - Open Source for Edge & Consumer Hardware
In January 2026, Black Forest Labs released FLUX.2 [klein], the fastest variant in the family:
- Sub-second generation on modern GPUs
- 4B variant under Apache 2.0 - free for commercial use
- 9B variant under Non-Commercial License
- Only ~13 GB VRAM for the 4B variant - runs on RTX 3090/4070
