FLUX.1 Schnell
The FLUX.1 Schnell model is a 12 billion parameter rectified flow transformer that generates high-quality images from text descriptions. It's trained using latent adversarial diffusion distillation, which allows it to produce images in just 1 to 4 steps, matching the performance of closed-source alternatives. With its cutting-edge output quality and competitive prompt following, this model is a powerful tool for generating images. But how does it work? Simply provide a text prompt, and the model will use its advanced algorithms to create a high-quality image. It's available for use under the apache-2.0 licence for personal, scientific, and commercial purposes, and can be used with the diffusers python library or in Comfy UI for local inference. However, keep in mind that the model may amplify existing societal biases and may struggle with complex or nuanced scenarios.

Capabilities
The FLUX.1 [schnell] model is a powerful tool that can generate images from text descriptions. But what does that really mean? Let’s break it down.
Generating Images
With this model, you can create images from text prompts. Want to see a picture of a cat holding a sign that says “hello world”? Just provide the prompt, and the model will generate an image for you.
Key Features
Here are some of the model’s key features:
- Cutting-edge output quality: It produces high-quality images that match the performance of ==Other Models==.
- Competitive prompt following: The model can follow text prompts accurately, making it a great tool for generating images that match your ideas.

Limitations
This model is not perfect. It’s not intended to provide factual information, and it may amplify existing societal biases. Always use it responsibly.
Lack of Factual Information
It’s not designed to provide factual information. It’s a statistical model that generates images based on patterns and associations in the data it was trained on. So, if you’re looking for accurate information, this model might not be the best choice.
Societal Biases
As with any statistical model, it may amplify existing societal biases. This means that the images it generates might reflect and even reinforce stereotypes or prejudices present in the data it was trained on.
Format
Architecture
This model uses a rectified flow transformer architecture, which is a type of neural network designed to generate images from text descriptions.
Data Formats
This model supports text input and generates images as output. Specifically, it takes in text prompts and produces images in the form of pixels.
Input Requirements
To use this model, you’ll need to provide a text prompt that describes the image you want to generate. For example:
prompt = "A cat holding a sign that says hello world"
The model also requires some technical parameters to be set, such as the number of inference steps and the guidance scale. Don’t worry too much about these - you can start with the default values and experiment later.
Output
The model generates an image based on your text prompt. You can save this image to a file using a library like Pillow.
Here’s an example of how to use this model with the diffusers library:
import torch
from diffusers import FluxPipeline
pipe = FluxPipeline.from_pretrained("black-forest-labs/FLUX.1-schnell", torch_dtype=torch.bfloat16)
pipe.enable_model_cpu_offload() # save some VRAM by offloading the model to CPU
image = pipe(prompt, guidance_scale=0.0, num_inference_steps=4, max_sequence_length=256).images[0]
image.save("flux-schnell.png")
Note that this code assumes you have the diffusers library installed and have replaced the prompt variable with your own text prompt.
Special Requirements
Keep in mind that this model is a large model with 12 billion parameters, so it may require significant computational resources to run. Additionally, the model is not intended to provide factual information and may amplify existing societal biases.
Before using this model, make sure you’ve read and understood the limitations and out-of-scope use cases outlined in the documentation.
