Descrição da fonte
Basic ComfyUI workflow for Chroma Diffusion
Necessary extension , put into "ComfyUI\custom_nodes" folder:
https://github.com/lodestone-rock/ComfyUI_FluxMod
Models folder same as for Flux:
"ComfyUI\models\unet"
"ComfyUI\models\clip"
Chroma GGUF models run same as normal ones, use "Load Chroma Diffusion Model" and "Padding Removal" custom nodes with T5 text encoder only.
Checkpoints for GPU's with high VRAM :
https://huggingface.co/lodestones/Chroma/tree/main
Checkpoints for GPU's with medium VRAM :
https://huggingface.co/silveroxides/Chroma-GGUF/tree/main
T5 text encoder (e4m3fn preferred for medium VRAM):

Suggested parameters to use:
I prefer euler ancestral with beta scheduler as it follows prompt better than just euler beta or other combinations as I experimented.
It produces a lot of dots look like trypophobia hell and noise clusters at image edges. So "ModelSamplingFlux" with "max_shift" = 1.5 "base_shift" = 0.5 improves quality pretty much.
Other parameters same as for Flux:
good results at 25 steps with CFG 4.0-5.0, faster at 20 steps

Comentário gerado por IA
Explicação gerada por IA com base nos detalhes da fonte e da configuração. As sugestões são claramente identificadas.
Propósito
This ComfyUI workflow is for generating Chroma Diffusion images from a text prompt, using a Chroma checkpoint and T5 text encoder; its named VAEDecode and SaveImage components suggest decoded images can be saved as output.

Entradas e saídas
For Chroma GGUF models, the description specifies a T5 text encoder only and the custom nodes “Load Chroma Diffusion Model” and “Padding Removal.”
Choose a Chroma checkpoint from the listed high- or medium-VRAM collections; e4m3fn is preferred for the T5 encoder on medium VRAM.
Configuração
Install the ComfyUI_FluxMod extension in ComfyUI\custom_nodes.
Place model files in ComfyUI\models\unet and ComfyUI\models\clip.
Dependências
Named model files include chroma-unlocked-v16-Q4_0.gguf and stableDiffusion3SD3_textEncoderT5E4m3fn.safetensors.
Other named components are ChromaDiffusionLoader, ChromaPaddingRemoval, CLIPLoader, CLIPTextEncode, EmptyLatentImage, and KSampler.
The named list also includes ModelSamplingFlux, SaveImage, VAEDecode, and VAELoader.
Configuração
Try Euler ancestral with a beta scheduler as a starting setting; the description’s author prefers it to Euler beta and other combinations.
Sugestão · não verificado
If dot-like marks or edge noise appear, try ModelSamplingFlux with max_shift = 1.5 and base_shift = 0.5.
Sugestão · não verificado
The description suggests 25 steps with CFG 4.0–5.0 and also mentions 20 steps as an option.

Precauções
No model-use license is listed; check the applicable usage terms before using the checkpoint or encoder.
