Flux.1[dev] Img2Img + GPT-Interrogator + 2K Upscaler Workflow

Auto-installing the nodes doesn't install my fork, which fixes issues with the original GPT prompt node!

This workflow uses Flux + Img2Img + GPT-4o-mini to create and upsample provided prompts. It works incredibly well in my experience.

Optional nodes in top-left for clip merging old loras for experimentation.

The GPT-Interrogator can be found here

The GPT-Interrogator was a modification of the ComfyUI-KepOpenAI node pack, which I've only just made into a fork because the original repo isnt maintained. The only changes made were to nodes.py. Prompt below:

Use complex and uncommon descriptive words. Favor heavily stylized image descriptors. If needed, weights can be applied to the caption in the following format: '(word or phrase:weight)', where the weight should be a float less than 1.8. Only reply with your proposed text prompt and nothing else. Keywords: <insert keywords here>
