Regarding my previous post about asking the Perchance devs what specific version of Chroma Flux they were using, while doing a bit of research, Google’s AI overview lead me to Perchance using Chroma Flux Radiance. I looked up Chroma Flux Radiance on Hugging Face, generated some images in my usual style on a Hugging Face demo as a test, compared the images I generated with Perchance, and it was 100% match. The images were strongly similar/identical. And after some realization, I confirmed the model on Perchance was Chroma Flux Radiance. And I am proud to announce:

Perchance uses Chroma Flux Radiance!
