Chroma (experimental)
Chroma is a diverse open-source model based on the Flux architecture. It can generate photography and various art styles.
It's currently still in a "raw" state. When optimized versions, finetunes and control models come out in the future it will allow to cover more of the plugin features.
Model download (manual)
Download one of these and put it in /models/diffusion_models (the unet folder also works):
- BF16: chroma-unlocked-v50.safetensors
- FP8: chroma-unlocked-v50_float8_e4m3fn_learned_svd.safetensors
- Quantized versions (GGUF)
You also need VAE and text encoder (T5). They are the same as Flux, if you have that running you can skip.
- ae.safetensors →
/models/vae - t5xxl_fp8_e4m3fn_scaled.safetensors →
/models/text_encoders
The Flux discussion has some more information. The prerequisites are the same, but note that LoRA, Control models, etc. are not compatible.
Important
Make sure ComfyUI & comfyui-tooling-nodes are up-to-date if you're running a custom server!
How to Use
There is a built-in Chroma style with recommended settings. Use natural language to prompt.
