European frontier AI lab behind the FLUX image generation models
Black Forest Labs is the German AI research lab founded in 2024 by Robin Rombach and the original Stable Diffusion authors. Its FLUX image-generation models have rapidly become the open-weights standard, embedded across Grok, X, and hundreds of consumer apps. The company raised $300M in a Series B at a $3.25 billion post-money valuation in December 2025, led by Salesforce Ventures, and has emerged as one of Europe's most credible AI sovereignty plays alongside Mistral.
