Flux Dev has been the talk of the month and many amazing developments already showing up in the opensource community, I’ve been experimenting and documenting many of the latest finding here on the blog so do checkout “flux” search to find all the posts.

In this post I will share my workflow of this Flux Dev (Image to prompt) with Upscaler workflow. Over the past years I’ve created so many images and with the advancement of tools like IPAdapters we hardly need to write a prompt to generate similar images. So as we don’t have anything like IPAdapters at the moment, I created this workflow which can generate the prompt to feed to the Flux model.

The workflow is running fine with 16GB and uses the Flux Dev Fp8 so it will work with 12GB as well.

Try to play with Task setting in Florence2Run node, i’ve set it to more_detailed_caption but you can scale it back for shorter prompt. Other settings to try would be caption or detailed_caption.

Must Do

In order to make sure these new workflows work for you you must do the following:

• Update ComfyUI so you have the latest version
• Install any Missing nodes using ComfyUI Manager

Workflow

The workflow is provided as PNG and JSON file so you can use either to import the workflow into ComfyUI. Simply drag and drop either of these files on your ComfyUI and you will be up and running in no time, make sure you have completed the Must Do above.

Flux Dev Image to Prompt with Upscaler (1492 downloads )

The workflow is easy to follow and comes with some notes to help you understand how to control some settings. The upscaler is set to 2x but works at 4x as well, just takes longer. I’m also embedding the realism LoRA of Flux Dev so you can generate realistic details in the final image.

Of course if you have any questions or comments don’t hesitate to share it below.
