I strictly tested the new FLUX.2 Klein models for the last 48 hours, running them on everything from an RTX 4090 to a struggling 12GB RTX 3060. The verdict? It is incredibly fast, but the workflow is full of traps.
If you tried loading this recently, you likely hit the RuntimeError: mat1 and mat2 shapes cannot be multiplied crash or saw generation speeds tank just by changing resolutions. I found the fixes.
This is a summarized guide. For the full JSON workflow and download files, check the original article on my site.
