Run flux with negative prompting via 2 different methods in ComfyUI. Tested on a 16GB RTX A4000 and the fp8 dev model. Affects performance dramatically - approx 2x slower with Dynamic Thresholding, approx 3x slower with Perpendicular Negative Guidance, but it works.
The Flux.1-schnell and merged dev-schnell models don't appear to be compatible with either method.
Demo pics: Prompt is "4k photo, high quality, in a European forest,"
Negative Prompt is " "path, trail"
Description
Implementation of the DynamicThresholding method as described by /u/Total-Resort-3120 on reddit but with a simpler workflow.
Stronger CFG=Stronger prompt guidance for both + and - prompt.
Recommend CFG above 2.

For anyone who wants to try PerpNeg on 8gb vram: generating time increased x3 time, and x2 for dynamic thresholding with cgf 3
Using PerpNegAdaptiveGuidance instead improves generation time considerably with a minimal effect on results, get it here: https://github.com/asagi4/ComfyUI-Adaptive-Guidance
Thanks for this!
It would have help to know what you put in the negative prompt to understand the difference between the images.
I've updated the description. Prompt is "4k photo, high quality, in a European forest,"
Negative Prompt is " "path, trail"
