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 original Latent Diffusion and Stable Diffusion team from LMU Munich and Stability AI. Headquartered in Freiburg, Germany, the lab raised a $31M seed round led by Andreessen Horowitz and launched the FLUX.1 family in August 2024 with three tiers: FLUX.1 [pro] (closed, API-only, highest quality), FLUX.1 [dev] (open weights, non-commercial, near-pro quality) and FLUX.1 [schnell] (open weights Apache 2.0, distilled few-step).

Arhitektuur

Rectified-flow Diffusion Transformer (DiT)

FLUX.1 [dev] is the open-weights research variant of the FLUX.1 family, providing near-FLUX.1 [pro] quality with publicly downloadable weights. The architecture is a rectified-flow Diffusion Transformer (DiT) with approximately 12B parameters, trained with the flow-matching objective from the SD3 paper (Esser et al. 2024). It uses T5-XXL plus CLIP-L as parallel text encoders, allowing both long descriptive prompts and short keyword-style prompts. Image tokens come from a learned 16x latent VAE. Sampling typically uses 28-50 flow-matching steps with the Euler sampler at guidance ~3.5. FLUX.1 [dev] is guidance-distilled from a teacher and uses 'guidance' as a conditioning input rather than classifier-free guidance at inference, simplifying multi-step deployment. The model produces images up to 2 MP with strong prompt adherence, photorealistic detail and notably good in-image text rendering.

Parameetrid
~12B parameters
Kontekst
512 tokenit

VÔimalused

  • Near-state-of-the-art photorealism for an open model
  • Up to 2 MP output resolution (1MP standard)
  • Strong prompt adherence via T5-XXL
  • Good in-image text rendering (short strings)
  • Open weights — self-hostable, fine-tunable
  • ControlNet, LoRA and IP-Adapter ecosystem
  • Compatible with FLUX Tools (Fill, Canny, Depth, Redux)
  • Best for: self-hosted creative pipelines, custom fine-tunes, research, ControlNet workflows.

Treening ja litsents

Pretrained on a large licensed and publicly available image-text dataset; then distilled from a teacher to produce the [dev] guidance-distilled checkpoint. Exact composition and token counts are not disclosed.

Litsents: FLUX.1 [dev] Non-Commercial License — free for research and personal use; commercial use requires a separate agreement with Black Forest Labs.

Turvalisuse testimine: Baseline safety filters at the API tier; the open weights ship without an integrated safety classifier and operators are expected to add their own moderation.

Teadaolevad piirangud

  • Non-commercial license restricts production use
  • Lower quality than FLUX.1 [pro] on fine details
  • Slow on consumer GPUs without quantisation
  • Hands and complex small text still imperfect
