All these workflows had slight flaws with missing buttons or misplaced elements. The workflows above fix this.
OLD-Image GGUF Workflow to fine-tune and upscale an image with lora and prompt support.

OLD-Final GGUF Updated the workflow for GGUF models

OLD-Final Rev A Same as the Final workflow, but adds a button to disable fine-tune and both fine-tune and upscaling are off.

OLD-Final Combines both finetune and the 4x Upscaler (which can be turned off).

Version 1.5 Streamlines the workflow by introducing a multi-LoRA picker, eliminating separate nodes for each LoRA. Adds a button to disable the upscale workflow and removes the "Save to webp" node.

Version 1.4 This version fixes the faint lines that appeared in upscaled images with the previous method.

Version 1.3 adds support for multiple loras.

Version 1.2 cleans up the workflow and removes the 4x upscaler.

Version 1.1 modifies the Lora connection to strengthen its weight and also updates the upscale method.

A lot of peole seem to be asking for a workflow to load LoRAs with flux in ComfyUI.
