Taust

Teave Black Forest Labs kohta

Asutatud 2024 · Freiburg, Germany

Black Forest Labs was founded in August 2024 by Robin Rombach, Patrick Esser, Andreas Blattmann and Dominik Lorenz, the team that created Latent Diffusion at LMU Munich and Stable Diffusion at Stability AI. Headquartered in Freiburg, Germany, the lab raised a $31M seed round led by Andreessen Horowitz and has since released the FLUX.1 family and FLUX 1.1 series. FLUX 1.1 [pro] (released October 2024) and the higher-resolution FLUX 1.1 [pro] Ultra (released November 2024) are the flagship commercial tiers, available only through the Black Forest Labs API and partner platforms such as Replicate, fal.ai and Together AI.

Arhitektuur

Rectified-flow Diffusion Transformer (DiT) with native 4 MP rendering

FLUX 1.1 [pro] Ultra is Black Forest Labs' highest-quality commercial image model, released as an API-only tier in November 2024. It builds on the FLUX 1.1 [pro] backbone — a rectified-flow Diffusion Transformer trained with the flow-matching objective from the SD3 paper (Esser et al. 2024) — but is fine-tuned and architecturally extended to produce up to 4 megapixels (2048x2048 or 1568x2520) natively without tiling or super-resolution. Black Forest Labs reports that Ultra achieves these resolutions with the same speed as standard FLUX 1.1 [pro] thanks to architectural and inference optimisations including grouped attention, FP8 inference and improved noise schedules. A complementary 'Raw' mode is exposed that produces less stylised, more photographic outputs. The model uses T5-XXL plus CLIP-L text encoders, the standard 16x latent VAE and 28-50 flow-matching sampling steps.
