`FLUX.1 Depth [dev] LoRA` is a LoRA extracted from [FLUX.1 Depth [dev]](https://huggingface.co/black-forest-labs/FLUX.1-Depth-dev), a 12 billion parameter rectified flow transformer capable of generating an image based on a text description while following the structure of a given input image.
For more information, please read our [blog post](https://blackforestlabs.ai/flux-1-tools/).
The LoRA is applicable to [FLUX.1 [dev]](https://huggingface.co/black-forest-labs/FLUX.1-dev).

# Key Features
1. Cutting-edge output quality.
2. It blends impressive prompt adherence with maintaining the structure of source images based on depth maps.
3. Trained using guidance distillation, making `FLUX.1 Depth [dev] LoRA` more efficient.
4. Open weights to drive new scientific research, and empower artists to develop innovative workflows.
5. Generated outputs can be used for personal, scientific, and commercial purposes as described in the [`FLUX.1 [dev]` Non-Commercial License](https://huggingface.co/black-forest-labs/FLUX.1-dev/blob/main/LICENSE.md).

# Usage
We provide a reference implementation of `FLUX.1 Depth [dev]`, 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 Depth [dev]` are encouraged to use this as a starting point.

## API Endpoints
`FLUX.1 Depth [pro]` is available in our API [bfl.ml](https://docs.bfl.ml/)

## Diffusers

To use FLUX.1-Depth-dev-lora with the 🧨 diffusers python library, first install or upgrade `diffusers`, `peft`, and `image_gen_aux`.

```bash
pip install -U git+https://github.com/huggingface/diffusers
pip install git+https://github.com/asomoza/image_gen_aux.git
pip install -U peft
```

Then you can use the `FluxControlPipeline` to run it:

```py
import torch
from diffusers import FluxControlPipeline, FluxTransformer2DModel
from diffusers.utils import load_image
from image_gen_aux import DepthPreprocessor

pipe = FluxControlPipeline.from_pretrained("black-forest-labs/FLUX.1-dev", torch_dtype=torch.bfloat16).to("cuda")
pipe.load_lora_weights("black-forest-labs/FLUX.1-Depth-dev-lora", adapter_name="depth")
pipe.set_adapters("depth", 0.85)

prompt = "A robot made of exotic candies and chocolates of different kinds. The background is filled with confetti and celebratory gifts."
control_image = load_image("https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/robot.png")

processor = DepthPreprocessor.from_pretrained("LiheYoung/depth-anything-large-hf")
control_image = processor(control_image)[0].convert("RGB")

image = pipe(
    prompt=prompt,
    control_image=control_image,
    height=1024,
    width=1024,
    num_inference_steps=30,
    guidance_scale=10.0,
    generator=torch.Generator().manual_seed(42),
).images[0]
image.save("output.png")
```
