| | ![FLUX.1 [dev] Grid](./dev_grid.jpg) |
| | |
| | `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](https://blackforestlabs.ai/announcing-black-forest-labs/). |
| | |
| | # Key Features |
| | 1. Cutting-edge output quality, second only to our state-of-the-art model `FLUX.1 [pro]`. |
| | 2. Competitive prompt following, matching the performance of closed source alternatives . |
| | 3. Trained using guidance distillation, making `FLUX.1 [dev]` 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 [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 [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](https://docs.bfl.ml/) (currently `FLUX.1 [pro]`) |
| | - [replicate.com](https://replicate.com/collections/flux) |
| | - [fal.ai](https://fal.ai/models/fal-ai/flux/dev) |
| | - [mystic.ai](https://www.mystic.ai/black-forest-labs/flux1-dev) |
| | |
| | ## ComfyUI |
| | `FLUX.1 [dev]` is also available in [Comfy UI](https://github.com/comfyanonymous/ComfyUI) for local inference with a node-based workflow. |
| | |
| | ## Diffusers |
| | |
| | To use `FLUX.1 [dev]` 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-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. |
| |
|
| | # 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. |
