Bakgrunnur

Um Black Forest Labs

Stofnað 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).

Arkitektúr

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.

Breytur: ~12B parameters
Samhengi: 512 tákn

Geta

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.

Þjálfun og leyfi

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.

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

Öryggispróf: 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.

Þekkt takmörk

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
