Just added fp16 for v.3
About 2.0 version
Welcome to version 2.0! It’s packed with changes compared to the last one, but trust me, they’re all upgrades. I’ve been torturing this model for ages before giving it the green light to meet the world. Realism got a serious facelift, but don't worry, it can still rock any other style you throw at it.
It swallows LoRAs for Chroma like breakfast. When it comes to Flux.1 - Krea, it sweats a little bit more, but hey, it gets the job done! For this version, just stick to the basic ComfyUI workflow to keep your sanity, though feel free to experiment with the rest.
My personal sweet spot is euler_ancestral (er_sde) - beta, 10-14 steps with 2-2.6 CFG. But hey, tastes are like prompts, everyone has their own. For example, if you use ddim_uniform, you can crank the CFG all the way up and watch the camera run away into a wide shot. As for aspect ratios and resolutions? I'm currently in an open relationship with all of them; they all work great. Quick edit, you can use seed_2 or _3 for better results but at a heavy speed cost.
If your GPU is crying for mercy, do yourself a favor: generate at 512 or 768, pick your favorites, and upscale them later (fun fact: this thing is an absolute beast of an upscaler).
A couple of pro-prompting tips: use (candid photography) if you want to keep things real and avoid getting accidental cartoons. Keep in mind that (candid photo) is a different beast, less stylized, more of an 'amateur holding a phone' vibe. I always use "motion blur" in negative, except when I want a more amateurish feel.
If you enjoy playing with it, don't be shy, drop your findings and your best generations below. Enjoy!
Chroma Merge
This model is a custom merge designed to streamline the power of Chroma for everyday use. By combining Chroma HD with Cenkrechro V25 and GonzaloMoChroma, I’ve aimed to create a "best of all worlds" experience that retains the iconic character and deep knowledge of the base Chroma model while significantly improving generation speed and ease of use.
What’s inside:
Base: Chroma HD
Additions: Cenkrechro V25 & GonzaloMoChroma
Optimizations: Integrated LoRAs for improved anatomy and lighting consistency.
Why this merge?
In my opinion, Chroma is the best model currently available.. My goal is to bring more creators into the Chroma community by providing a versatile, "plug-and-play" version of this incredible architecture.
Recommended Settings:
Sampler: er_sde
Steps: 10-14
CFG Scale: 4-5 (with the png workflow)
I suggest the GNER-T5 clip
I hope you enjoy the results! If you like the model, please share your generations in the gallery below—I’d love to see what you create.

i love you❤️
on your next release; could you do a mxfp8 version?
Is that the Nvfp4 ?
@panorios no, mxfp8 is a mix of fp16 and fp8 but mostly fp8 speed and size. IDK if that's the best way to explain it, but that's what it does i believe.
@delta45424155 I am sorry, I don't know how to do this but I will take a look into it.
Hey would it be possible to release the full fp16 model of version 2.0?
Sure, soon.
First, again a great model V2, just like the first one. Can u give me a example how to upscale the image. Or share a workflow to use
Hey thanks, I use Krita mostly but all methods that require a model like ultimate upscaler, in comfy, should work fine.
Do you still use the workflow of the V1? or can you share a new one
@warsound75 No, for this I use the default chroma workflow. Check the images I uploaded the have the workflow and settings.
Is there any fp16 for this v2 ?
Is there an fp16 version of this or only fp8? Love the model.
Too bad Chroma model is not that popular, I personally like it. But cmon, there must be an alternative place to download BF16 version if not CivitAI... Anyone?
