Introduction:

Wrapped Joy Caption alpha 2 node for comfyui from https://huggingface.co/spaces/fancyfeast/joy-caption-alpha-two Easy use, for GPU with less 19G, please use nf4 for better balanced speed and result. This Node also took a reference from /chflame163/ComfyUI_LayerStyle and https://huggingface.co/John6666/joy-caption-alpha-two-cli-mod

Please notice🔥:

🔥BF16 need at least 19GB free VRAM to run

🔥NF4 need at least 10GB free VRAM to run

🔥Insufficient VRAM will lead to error in Comfyui

Usage:

-inside comfyui

-click comfyui manager

-Install Via git Url https://github.com/TTPlanetPig/Comfyui_JC2 or inside the folder ./comfyui/custom_nodes run

git clone https://github.com/TTPlanetPig/Comfyui_JC2

-for python_embeded comfyui version, inside folder ./comfyui/custom_nodes/Comfyui_JC2 run

../../../python_embeded/python.exe -m pip install -r requirements.txt

I will assume you have the pytorch ready in your PC, in case you don't, install from here:

pip install torch==2.4.0 torchvision==0.19.0 torchaudio==2.4.0 --index-url https://download.pytorch.org/whl/cu121  
# (NOT Recommended if you don't familar with embeded python)

Model preparation:

-clip vision: https://huggingface.co/google/siglip-so400m-patch14-384/tree/main download all files and place in ComfyUI\models\clip_vision\google--siglip-so400m-patch14-384

-LLM: https://huggingface.co/unsloth/Meta-Llama-3.1-8B-Instruct download all files and place in ComfyUI\models\LLM\unsloth--Meta-Llama-3.1-8B-Instruct

-Joy capiton lora: https://huggingface.co/spaces/fancyfeast/joy-caption-alpha-two download all files and place in ComfyUI\models\Joy_caption\cgrkzexw-599808, i will suggest you use huggingface-cli to avoid mistaken on the names.

• Or you can download the models here and unzip it into your folder *
• https://pan.baidu.com/s/1yYRlDKclehSPv-tUVwfVHw?pwd=b84c *

Make sure your model is well placed as below.

Key options:

1. For 3090/4090 use bf16 otherwise nf4. please notice nf4 accuracy is lower than bf16, you can directly figure out.

2. For differnt purpose on the prompts

   

3. not always longer is better:

   

4. if enabled, the loaded clip,llm,lora model will not offload

   

5. if enabled, all the extra option will be effective. if disabled, even you enabled in detail options.

   

6. Must use together to be affective,

   ,

Enjoy!
