      Create a painting in the style of 16th or 17th century art, reminiscent of
      the works of Caravaggio or Rembrandt. The scene should have dramatic
      chiaroscuro, with deep shadows and bright highlights. Brushstrokes should
      be fluid and delicate, blending colors subtly to achieve a realistic
      texture. Use a warm, earthy color palette, emphasizing deep reds, browns,
      and ochres, with golden light casting soft highlights on the subject. The
      composition should be balanced and harmonious, with attention to classical
      proportions and depth, evoking the grandeur and realism of Renaissance and
      Baroque masterpieces. The image to be depicted is that of a Templar
      dressed in a white tunic with a painted red cross and a red sheer organza
      cape. He is kneeling in a dark place while contemplating the golden Holy
      Grail. The scene is divided into two parts: one hellish and one heavenly
      to highlight the contrast between the two dimensions in which he finds
      himself.  On one side elements such as Crows dry branches and thorns and
      on the other elements such as Roses Lilies and Dahlias. On one side a dove
      on the other a black crow

FLUX.1 [dev] is a 12 billion parameter rectified flow transformer capable of generating images from text descriptions. For more information, please read our blog post.

Key Features

Cutting-edge output quality, second only to our state-of-the-art model FLUX.1 [pro].
Competitive prompt following, matching the performance of closed source alternatives .
Trained using guidance distillation, making FLUX.1 [dev] more efficient.
Open weights to drive new scientific research, and empower artists to develop innovative workflows.
Generated outputs can be used for personal, scientific, and commercial purposes as described in the FLUX.1 [dev] Non-Commercial License.

Usage

We provide a reference implementation of FLUX.1 [dev], as well as sampling code, in a dedicated github repository. Developers and creatives looking to build on top of FLUX.1 [dev] are encouraged to use this as a starting point.

API Endpoints

The FLUX.1 models are also available via API from the following sources

bfl.ml (currently FLUX.1 [pro])
replicate.com
fal.ai
mystic.ai

ComfyUI

FLUX.1 [dev] is also available in Comfy UI for local inference with a node-based workflow.

Diffusers

To use FLUX.1 [dev] with the 🧨 diffusers python library, first install or upgrade diffusers

pip install -U diffusers

Then you can use FluxPipeline to run the model

import torch
from diffusers import FluxPipeline

pipe = FluxPipeline.from_pretrained("black-forest-labs/FLUX.1-dev", torch_dtype=torch.bfloat16)
pipe.enable_model_cpu_offload() #save some VRAM by offloading the model to CPU. Remove this if you have enough GPU power

prompt = "A cat holding a sign that says hello world"
image = pipe(
    prompt,
    height=1024,
    width=1024,
    guidance_scale=3.5,
    num_inference_steps=50,
    max_sequence_length=512,
    generator=torch.Generator("cpu").manual_seed(0)
).images[0]
image.save("flux-dev.png")

Limitations

This model is not intended or able to provide factual information.
As a statistical model this checkpoint might amplify existing societal biases.
The model may fail to generate output that matches the prompts.
Prompt following is heavily influenced by the prompting-style.
