Intent:
Provide a clean reference implementation for Flux.2 Klein text-to-image generation.
This workflow focuses on simplicity,reproducibility, and education rather than including every available feature.
----------------------------------------------------
Version 1.0
Created as a simple reference workflow for users getting started with Flux.2 Klein.
If using non-gguf models, you may need to change the model loaders accordingly. The remainder of the workflow should remain unchanged.
Some models may produce washed-out images at lower resolutions (for example, Dark Beast).
Purpose:
✓ Educational
✓ Minimal
✓ Easy to extend
Verified
✓ Text-to-Image
Verified Settings:
✓ CFG : 7.0
✓ Sampler : Euler
✓ Scheduler : Simple
These settings were used to validate this workflow and are recommended as the baseline configuration.
Recommended Resolution :
✓ 384×640 (Observation - size picker doubles the resolution automatically when combined with Flux.2 Klein model, If you want exact dimensions, use 'Empty Latent Image' node instead)
Hardware Tested:
✓ RTX 2080 (8 GB)
✓ 64 GB System RAM
✓ ComfyUI 0.27.0
