![FLUX.1 [schnell] Grid](./schnell_grid.jpeg) |
|
|
|
`FLUX.1 [schnell]` is a 12 billion parameter rectified flow transformer capable of generating images from text descriptions. |
|
For more information, please read our [blog post](https://blackforestlabs.ai/announcing-black-forest-labs/). |
|
|
|
# Key Features |
|
1. Cutting-edge output quality and competitive prompt following, matching the performance of closed source alternatives. |
|
2. Trained using latent adversarial diffusion distillation, `FLUX.1 [schnell]` can generate high-quality images in only 1 to 4 steps. |
|
3. Released under the `apache-2.0` licence, the model can be used for personal, scientific, and commercial purposes. |
|
|
|
# Usage |
|
We provide a reference implementation of `FLUX.1 [schnell]`, as well as sampling code, in a dedicated [github repository](https://github.com/black-forest-labs/flux). |
|
Developers and creatives looking to build on top of `FLUX.1 [schnell]` 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](https://docs.bfl.ml/) (currently `FLUX.1 [pro]`) |
|
- [replicate.com](https://replicate.com/collections/flux) |
|
- [fal.ai](https://fal.ai/models/fal-ai/flux/schnell) |
|
- [mystic.ai](https://www.mystic.ai/black-forest-labs/flux1-schnell) |
|
|
|
## ComfyUI |
|
`FLUX.1 [schnell]` is also available in [Comfy UI](https://github.com/comfyanonymous/ComfyUI) for local inference with a node-based workflow. |
|
|
|
## Diffusers |
|
To use `FLUX.1 [schnell]` with the 🧨 diffusers python library, first install or upgrade diffusers |
|
|
|
```shell |
|
pip install -U diffusers |
|
``` |
|
|
|
Then you can use `FluxPipeline` to run the model |
|
|
|
```python |
|
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. Remove this if you have enough GPU power |
|
|
|
prompt = "A cat holding a sign that says hello world" |
|
image = pipe( |
|
prompt, |
|
guidance_scale=0.0, |
|
num_inference_steps=4, |
|
max_sequence_length=256, |
|
generator=torch.Generator("cpu").manual_seed(0) |
|
).images[0] |
|
image.save("flux-schnell.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. |
|
|
|
# Out-of-Scope Use |
|
The model and its derivatives may not be used |
|
|
|
- In any way that violates any applicable national, federal, state, local or international law or regulation. |
|
- For the purpose of exploiting, harming or attempting to exploit or harm minors in any way; including but not limited to the solicitation, creation, acquisition, or dissemination of child exploitative content. |
|
- To generate or disseminate verifiably false information and/or content with the purpose of harming others. |
|
- To generate or disseminate personal identifiable information that can be used to harm an individual. |
|
- To harass, abuse, threaten, stalk, or bully individuals or groups of individuals. |
|
- To create non-consensual nudity or illegal pornographic content. |
|
- For fully automated decision making that adversely impacts an individual's legal rights or otherwise creates or modifies a binding, enforceable obligation. |
|
- Generating or facilitating large-scale disinformation campaigns. |
