Image generation models, a widely used subset of generative AI, are designed to interpret written language and convert text into images in almost any artistic style. Pushing the boundaries of image generation, Black Forest Labs has introduced a new series of models—optimized for PC and workstation use—that run fastest on GeForce RTX and NVIDIA RTX GPUs.
Fluxible Capabilities
FLUX.1 AI, developed by Black Forest Labs, is a suite of text-to-image models built on the diffusion transformer (DiT) architecture. This design allows models with a large number of parameters to remain efficient. FLUX models are trained on 12 billion parameters, ensuring high-quality image generation.
DiT models are both efficient and computationally demanding, making NVIDIA RTX GPUs crucial for running these models—particularly the largest ones, which cannot operate on non-RTX GPUs without significant modifications. Flux models now support NVIDIA’s TensorRT software development kit, boosting their performance by up to 20%. Users can explore Flux and other models with TensorRT via ComfyUI.
Flux Appeal
FLUX.1 stands out for producing high-quality, diverse images with excellent prompt adherence—meaning the AI accurately follows and executes instructions. Strong prompt adherence results in images that closely match the described elements, style, and mood in the text prompt, whereas weak adherence may lead to partial or complete deviation from the prompt.
FLUX.1 is especially notable for its precise rendering of human anatomy, including challenging features like hands and faces. It also excels at generating legible text within images, addressing a common issue in text-to-image models. This makes FLUX.1 particularly useful for projects requiring clear text representation, such as promotional content and book covers.
FLUX.1 AI is available in three versions, allowing users to choose the best fit for their workflow without sacrificing quality:
- FLUX.1 pro: Offers state-of-the-art image quality for enterprise users and is accessible via an API.
- FLUX.1 dev: A streamlined, free version of FLUX.1 pro, still delivering high-quality images.
- FLUX.1 schnell: The fastest version, perfect for local development and personal use, licensed under Apache 2.0.
The dev and schnell models are open source, and Black Forest Labs provides their weights on Hugging Face, fostering innovation and collaboration within the image generation community by enabling developers and researchers to build upon these models.
Community Adoption
The dev and schnell versions of Flux models have seen over 2 million downloads on Hugging Face within just three weeks of their release.
Users have praised FLUX.1 for its ability to create visually stunning, detailed, and realistic images, as well as its capacity to handle complex prompts without needing extensive parameter adjustments.
FLUX.1’s versatility across artistic styles, combined with its efficiency in generating images quickly, makes it an invaluable tool for both personal and professional projects.
Getting Started
Users can access FLUX.1 through popular platforms like ComfyUI. The community-run ComfyUI Wiki provides step-by-step guides to help users get started.
