    V1 - 6/23 - Initial Release - GGUF'S ARE HERE!

    ===========================================================================

    CRUX (chroma/flux) hybrid models are created by DR34MSC4PE with the best of both worlds:

    • In a blurb? It is a hybrid model between Chroma/Flux that puts back the removed components (modulation layers, etc) from FLUX.1-dev by selectively merging it with a special variant of C4PACITOR but, importantly, keeping Chroma's de-distilled (unchained) nature and output layers.

    • Can be used with Chroma or FLUX de-distilled workflows (CFG enabled)

    • Can even be used with flux.1-dev workflows, but you'll need to increase the FluxGuidance to > 4 for adherence most times. Sampler research into "what all works" is ongoing but has been surprising!

    • For the moment, it is recommended to use CHROMA or classic CFG enabled workflows (including negative prompts!) vs. FLUX unless you want to help research the boundaries with us!

    • Specific anime/illustration tuning to introduce some lost artistic concepts

    • NSFW tuned and capable of realism and artistic/anime images. Female anatomy is well represented as a result of CHROMA + C4PACITOR's advance knowledge on these subjects. It tends to lean toward the latter's style.

    • FLUX LoRA seem to work but testing is ongoing for efficacy.

    • We have not tested this in any inference tool except ComfyUI yet - YMMV! Keep us posted!

    Just tested in forge, and it works. What have you discovered for sampler/scheduler so far?

    Definitely not when treating it as FLUX checkpoint with the exception that I was able to to do a handful of decent images when using a flux guider of like 5-6 and the res2m and the Euler sampler. Beta scheduler.

    but that said it was still wild looking - at this point it should be treated as a Chroma checkpoint if you’re looking for immediate usability and not to play around helping us see what works and doesn’t.

    @c0ur4ge I've been using normal CFG of 6 and found either Beta or DDIM to be best. Still testing different samplers.

    @TheCasualPersuer interesting. I’ll have to check it out in forge after I kick out the GGUFs in the coming day or so. Please keep me posted! Love to see how it performs in different scenarios.
