Photonic Fusion Chroma - Debloated

Introducing the refined, BF16 version of the original model: Photonic Fusion Chroma - Debloated. I’ve taken the original 22GB beast and stripped away all the unnecessary "bloat" to bring you a proper 16+GB version that’s easier on your storage and VRAM, I’ve also tucked in a minor fix. Honestly, this checkpoint has been on a strict regimen of Ozempic to slim down to this fighting weight, but don't let the smaller size fool you; the Photonic structure and high-fidelity detail are punchier than ever. I recommend you delete V1 and save your disk space and some extra VRAM and use this version, this is the exact same model just slimmed down and better.

Huge thank you to VioletCrow for the Q4 GGUF version of my checkpoint, many in this community will be very grateful for your efforts to be able to use this model on far less VRAM now!!!

UPDATE 04/26/2026 and now the Q8 GGUF version as well!

Welcome to Photonic Fusion Chroma!

Man Chroma is a difficult beast to tame, after two failed attempts at a finetune the 3rd time was a charm. I thought I was going hang up my hat with my SDXL series but I am still around tinkering and I always wanted to add my own coat of paint to Chroma.

As always with my checkpoints it excels at male anatomy but the base Chroma model already did amazingly well at this I just trained in far more variety. I feel that anything base Chroma could do can still be done here but with more variety and with improved skin texture and more of that moodiness vibe I enjoy. And great news if you are not into gay males it still does women very well as well as all general types of art, fantasy art and animation styles. I hope you enjoy! ~~I have no plans at the moment to create any smaller quantized or GGUF versions sorry~~.

I’ve spent weeks grinding on my own custom finetunes for Photonic Fusion, but it wasn't quite hitting the exact vibe I wanted on its own. To get that specific lighting/mood, I merged my weights with dawncreates Chroma. So yes, I merged my custom finetune with this other amazing model to get the balanced look I wanted and I hope you enjoy the final output!

ComfyUI I recommend Res_2s + Beta57 (but almost as good and even slightly faster euler + beta)
Steps 25-40 (I usually go 28-30)
CFG: 3-6 (I usually go with 4)
Resolution: up to you it does well with all common aspect ratios
Upscaling: lanczos 1.5x-2x, 4x-ClearRealityV1, 18-20 Steps, CFG 3-4, 0.27-0.33 Denoising. Optional: SeedVR 3rd final upscale.

If you find a better combination of settings ass always I ask that you please share with the community in the comments below!

For some of the sample images I have used some amazing prompts found right here on CivitAI, I wanted to test some amazing prompts I have seen for Z-Image, Flux and other Chroma models to see how well they performed on mine. So thank you to those that share their prompts!

Lastly, in this version the model does struggle some with sexual positions. If I make a second version I hope to address this.

Thank you Lodestone - https://civitai.com/models/1330309/chroma

Thank you dawncreates - https://civitai.com/models/2086389/uncanny-photorealism-chroma

Also I don't believe in locking my models that are available on TensorHub or CivitAI behind a paywall like some do but I gladly accept donated --> Coffee and Beer <-- your donations help me to keep motivated to continue making new checkpoints and LoRA's for all our enjoyment! To those that are generous enough to throw me a few dollars I thank you! <3
