Update 26.11.24
This workflow eliminates the need for a face and skin detailer. The idea is to render directly at a significantly higher resolution and then correct any imperfections in the image using a simple ultimate upscaling process.

Additionally, image details are enhanced through the Detail Daemon and additional noise injection. In the initial samplers, the sigmas are split to allow the first steps to render with high guidance and the final steps with low guidance. This makes the images appear more natural and less AI-like.

This approach works very well but requires extremely powerful hardware and is not particularly fast. However, the resulting images are of exceptionally high quality.

Update 07.10.24

The workflow now supports GGUF models, improved ViT-L/14 CLIP, and has a significantly enhanced UltimateUpscaler thanks to the fill nodes.

Attention: The skin detailer with upscaler workflow is extremely hardware-intensive. On an RTX 3090, it takes about 10-12 minutes to generate a single image. If you want to generate images faster, please use the older workflow.

Flux is a 12 billion parameter model and it's simply amazing!!! Here’s a workflow from me that makes your face look even better, so you can create stunning portraits.

You can find the download links for the Flux model in the notes within the workflow.
