About FLUX.1 Dev
FLUX.1 Dev is an open-weight, guidance-distilled text-to-image model developed by Black Forest Labs, designed for non-commercial use. The model represents a leap forward in image synthesis, combining a powerful 12 billion parameter rectified flow transformer with cutting-edge diffusion techniques. With open access to its weights, FLUX.1 Dev empowers researchers, educators, and developers to create high-quality, diverse images from text prompts.
Key Features
- 12 Billion Parameter Rectified Flow Transformer: Enables advanced synthesis and high image fidelity.
- Guidance Distillation: Trained using guidance distillation for improved efficiency and faster image generation, rivaling closed-source alternatives.
- Open-Weight Architecture: Fully accessible weights for research, customization, and workflow innovation.
- Competitive Prompt Adherence: Matches or exceeds industry standards for prompt following and output quality.
- Non-Commercial License: Ideal for research, education, and personal projects.
- Efficient Hardware Requirements: Runs on consumer-grade GPUs with 8GB+ VRAM and 16GB RAM.

Improvements Over Previous Models
Compared to earlier FLUX models, FLUX.1 Dev introduces:
- Greater Efficiency: Through guidance distillation, images are generated faster with less computational overhead.
- Higher Quality Outputs: Image fidelity and prompt adherence are near parity with the premium FLUX.1 Pro model.
- Open Research Focus: Full model weights are released, enabling reproducibility and further innovation.
- Broader Accessibility: Designed to run on widely available hardware, lowering the barrier for experimentation.
How FLUX.1 Dev Stands Out
FLUX.1 Dev offers a unique combination of open access, efficiency, and high output quality. Unlike most leading text-to-image models (such as Midjourney or DALL-E 3), FLUX.1 Dev’s open-weight approach allows full transparency, reproducibility, and the potential for community-driven improvements. Its efficiency through guidance distillation means faster iteration cycles and powerful prototyping potential for artists, researchers, and students.
Example Usage in Python (HuggingFace Diffusers)
FLUX.1 Dev is available on HuggingFace under black-forest-labs/FLUX.1-dev. To use the model in Python:
from diffusers import DiffusionPipeline
pipeline = DiffusionPipeline.from_pretrained("black-forest-labs/FLUX.1-dev", torch_dtype="auto")
prompt = "A futuristic cityscape at sunset, vibrant and detailed"
image = pipeline(prompt).images[0]
image.save("flux_output.png")
Note: Accept the model’s non-commercial license on HuggingFace before downloading weights.
Access and Availability
- Open Weights: Download from HuggingFace FLUX.1 Dev
- Cloud APIs: Available through Replicate, Fal.ai, and Mystic.ai
- Local Inference: Supported in ComfyUI
