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.

Description
A different blockmerge technique with awesome results, imo the best so far. What do you guys think, which one do you prefer? Let me know so I can drop the fp16 as well.

Hi, i tested merge 3 a little bit. For me It looks improved compared to merge 2. A FP16 version would be great. Thanks for creating this fantastic model.
v3 rocks !! FP16 please :)
Very good job !
Q8_0 GGUF would be appreciated. It has better quality than FP8 while maintaining small file size. It runs better on my 12 GB VRAM system.
Im sorry, what text encoder and vae should i use to run fp8 model? Thanks!
Sampler: er_sde
Steps: 10-14
CFG Scale: 4-5 (with the png workflow) or 2-3 with the custom comfy one.
I suggest the GNER-T5 clip (you can use standard T5)
vae: flux
Thank you!
