v2 - adds Prompt cycler to autogenerate images with a text file list of prompts.

v3 -adds SeedVR2 to upscale images to 4K resolution while maintaining ALL the detail quality.

This is a condensed GGUF version of the ComfyUI template workflow for FLUX 2, designed with LOW VRAM USERS in mind.

replaces the diffusion model with GGUFs. optional GGUF text encoder as well for extremely low vram users. (for some reason the fp8 works just as well as the fp16 with WAY less resource use. BE WARNED the text encoder is HUGE, around 18gb for the fp8. for some reason it runs easily on my 8gb vram card with 16gb of regular ram, i think that is because the text encoder and gguf weights arent stored on the vram card at the same time so your either just running sampling steps or encoding it but never at the same time so it should run well on most pcs.)

IMPORTANT!!! :::

FluxGuidance node is tricky, for regular images just use 4.0 . for TEXT you may need to raise the value to 11.0 or 8.0 if artifacting is too strong.

FOR THOSE USING "cow_mistral" text encoder either install missing custom nodes or use the other text encoder file. its small and can fit on most cpus by default!

❗️IMPORTANT FOR PROMPT CYCLER IN VERSION 2❗️

Copy the address of the text file and paste it into the simple string node. REMOVE QUOTATIONS FROM BEGINNING AND END OF FILE ADDRESS OR THE CYCLER WONT RECOGNIZE THE FILE. Then feed the connector node into the text of the clip text encode node of your image generator, NOT THE NODE ITSELF. (Theres a smaller GREEN connector dot on the left side of the box of the clip text encode node, essentially your feeding the string into the box and not the clip nodes connector.)
