- 📦 Download the FLUX model, choosing between the dev version and the Schnell version, with the latter potentially prioritizing speed over quality.
- 🔍 Three different encoders are required, with links provided in the description, and should be saved under ComfyUI models in the respective folders.
- 🔄 The VAE model is also necessary, with two versions available depending on the FLUX version you choose, and should be placed in the VA folder.
- 🖼️ Open Art provides a simple workflow for FLUX, which can be downloaded and loaded onto the ComfyUI interface.
- 📝 Write a prompt describing the image you want to generate; there's a video tutorial on crafting good prompts if needed.
- 🎛️ Customize settings such as image width, height, seed, sampler, scheduler, steps, and select the appropriate VAE model for the best results.
- 💻 Be aware that FLUX can be resource-intensive, especially on GPUs with lower VRAM, and consider alternative versions or cloud-based solutions if needed.
- 🎉 The output images from FLUX are of high quality, with impressive details and realism, as demonstrated in the video.
- 📚 FLUX excels at generating text accurately and in context, making it powerful for various creative tasks.
- 🖌️ For even higher quality images, third-party image upscalers like Topaz Photo AI can be used to sharpen and upscale the generated images.
Q & A
What is FLUX and who developed it?
-FLUX is an incredible new image generation model developed by Black Forest Labs, the same team behind Stable Diffusion.
How does FLUX compare to other image generators like M journey and Dolly?
-FLUX is considered as good, if not better than other leading image generators in terms of overall quality and realism. It particularly excels in rendering text and generating human hands.
What is ComfyUI and why is it needed for using FLUX?
-ComfyUI is a user interface that allows users to run the FLUX model on their computers. It's required for setting up and operating FLUX locally.
Which versions of the FLUX model are suitable for local use?
-There are two main versions suitable for local use: the dev version and the Schnell version. The Schnell version is reported to run faster, possibly prioritizing speed over quality.
What additional files are needed to set up FLUX with ComfyUI?
-Three different encoders and a VAE model are needed. There are two versions of the VAE model, one for each of the FLUX versions (dev and Schnell).
Where should the downloaded FLUX model and other files be placed?
-The downloaded FLUX model should be placed in the 'ComfyUI models' under the 'unet' folder. The encoders go in 'ComfyUI models clip', and the VAE model in 'ComfyUI models' inside the 'VA' folder.
How can one get the simple workflow for FLUX?
-The simple workflow for FLUX can be downloaded from a page on OpenArt, and then dragged and dropped onto the ComfyUI interface.
What is the purpose of the prompt in the FLUX workflow?
-The prompt is a description that tells FLUX what image to generate. It's crucial for guiding the model to create the desired output.
What are some factors that can affect the speed and quality of image generation in FLUX?
-Factors include the choice between the dev and Schnell versions, the encoder used (e.g., default fp8 or T5 XXL fp16), the image dimensions, the seed setting, the sampler name, the scheduler, the steps value, and the selected VAE model.
What issues might users with lower-end GPUs encounter when using FLUX?
-Users with lower-end GPUs might experience slow generation times. Options to address this include using the Schnell version of FLUX, trying different encoders, or using cloud-based solutions like Think Diffusion.
How can the quality of generated images be improved further?
-The quality can be improved by using a third-party image upscaler like Topaz Photo AI, which sharpens and upscales the image, reintroducing details.

🖼️ Setting Up Flux Model with Comi UI
This paragraph introduces the Flux model developed by Black Forest Labs, creators of Stable Diffusion. It emphasizes Flux's superiority in image quality and realism over other leading image generators like M journey and Dolly. The script focuses on the process of setting up Flux on a computer using Comi UI, including installing Comi, downloading the model, and configuring the necessary files and settings. The video will guide viewers through the installation of the dev version of Flux, the download and placement of three encoders, and the selection of the VAE model. It also advises viewers to update Comi UI to the latest version and provides a link to a simple workflow for Flux on OpenArt.
📚 Flux's Text Rendering and Image Generation
The second paragraph demonstrates Flux's capabilities in text rendering and generating images with human hands. It showcases the model's ability to produce accurate text and character depictions, as well as its proficiency in generating realistic images. The script describes the process of generating a children's book cover with text and a character, highlighting the model's accuracy and design coherence with the prompt. It also discusses the generation of an image with human hands, noting the correct finger count and realism. The paragraph concludes with a mention of using a third-party image upscaler, Topaz Photo AI, to enhance and upscale the generated images, providing a before-and-after comparison to illustrate the improvements.
