Ostris Nodes ComfyUI

This is a collection of custom nodes for ComfyUI that I made for some QOL. I will be adding much more advanced ones in the future once I get more familiar with the API.

Installation

Just git clone this repo into your ComfyUI custom_nodes folder and restart.

cd <your_comfyui_folder>/custom_nodes
git clone https://github.com/ostris/ostris_nodes_comfyui.git
cd ostris_nodes_comfyui
pip install --upgrade -r requirements.txt

LLM Prompt Upsampling (BETA)

Based on the fantastic work of sayakpaul/caption-upsampling. It uses an LLM to expand your prompt into a more complex prompt with more descriptive detail.

WARNING: This is experimental. It will likely remove TI embeddings. It loads in 4bit mode but will still be VRAM hungry.

• LLM Pipe Loader - Loads the LLM pipeline to use
  • model_name (STRING) Huggingface model name e.g. HuggingFaceH4/zephyr-7b-beta
• LLM Prompt Upsampling - Upsamples a prompt
