What is FLUX.1?

FLUX.1 is an open-source AI image generation model developed by the founding team of Stable Diffusion. With 12B parameters, it is the largest text-based image model to date. It includes three variants: the top-performance FLUX.1 [pro], the open-source, non-commercial FLUX.1 [dev], and the fast and efficient FLUX.1 [schnell]. FLUX.1 stands out for its superior image quality, highly realistic human anatomy, and advanced cue word following capabilities, setting a new industry standard for AI image generation.

Features of FLUX.1

  • Large-scale parametersWith 12B (12 billion) parameters, it is one of the largest open-source text-to-image models to date.
  • Multimodal architectureBased on a hybrid architecture of multimodal and parallel diffusion Transformer blocks, it provides powerful image generation capabilities.
  • High-performance variantIt offers three different model variants with different performance and uses, including the professional version (FLUX.1 [pro]), the development version (FLUX.1 [dev]), and the fast version (FLUX.1 [schnell]).
  • Image qualityIt surpasses other popular models in terms of visual quality, cue word adherence, size/aspect ratio variability, font and output diversity.
  • Open source and accessibilitySome model variants, such as FLUX.1 [dev] and FLUX.1 [schnell], are open source and easy to study and use in non-commercial applications.
  • Technological innovationThe introduction of flow matching training methods, rotation position embedding, and parallel attention layers improves model performance and hardware efficiency.

Technical Principles of FLUX.1

  • Multimodal architectureFLUX.1 employs a multimodal architecture, which means that the model can process and understand multiple types of data simultaneously, such as text and images, thereby better capturing the correlations between different data.
  • Parallel Diffusion Transformer BlockThe model utilizes a parallel diffusion Transformer structure, an advanced neural network component that can efficiently process sequential data and enhance the model's ability to encode and decode information.
  • Stream matching training methodFLUX.1 improves upon traditional diffusion models using a flow matching method. This method is a general technique for training generative models, simplifying the training process and improving the quality of generated models.
  • Rotational Position EmbeddingThe model incorporates rotational position embedding, a special encoding method that enhances the model's ability to recognize features at different locations in an image, thereby improving the image's detail representation.
  • Parallel attention layerBy using a parallel attention mechanism, the model can simultaneously focus on multiple parts of the input sequence, which helps to capture long-distance dependencies and improve the accuracy of generated images.

How to use FLUX.1

  • Select the appropriate model variant:
    • FLUX.1 [pro]: Suitable for commercial applications that require top-tier performance and need to be accessed via API.
    • FLUX.1 [dev]: For non-commercial use, it is an open-source, guided distillation model available on HuggingFace.
    • FLUX.1 [schnell]: Suitable for local development and personal use, it is the fastest model and can also be obtained on HuggingFace.
  • Setting up the environment:For local deployment, you need to set up the Python environment and install the necessary dependency libraries.
  • Install FLUX.1:You can clone the official GitHub repository to your local environment using Git and install the necessary Python packages by following the guide.
  • Using API:For FLUX.1 [pro], you need to register and obtain an API key to access the model.
  • Write code:Write scripts to interact with the model and generate images, based on the official documentation or sample code.
  • Generate image:Using the interface provided by the model, input a text prompt, and the model will generate an image based on the text.

Below is a simple usage example, assuming you have already set up the environment and installed the necessary dependencies:

# 克隆FLUX.1 GitHub仓库
git clone https://github.com/black-forest-labs/flux

# 进入仓库目录
cd flux

source .venv/bin/activate

# 安装依赖
pip install -e '.[all]'

# 根据需要设置环境变量，例如指定模型权重路径
export FLUX_SCHNELL=path_to_flux_schnell_sft_file

# 使用提供的脚本进行图像生成
python -m flux --name 'FLUX.1 [schnell]' --loop
