ComfyUI LLM Helper

A collection of helper nodes for working with LLM APIs in ComfyUI, intended to complement other LLM custom nodes.

Installation

cd ComfyUI/custom_nodes
git clone https://github.com/bedovyy/ComfyUI-LLM-Helper
cd ComfyUI-LLM-Helper
pip install -r requirements.txt

Usage

LLMHelper GET /models

• Set your LLM server's base_url and select API key from environment variables (loaded securely from ComfyUI/.env).
• Click "Update model names" to query the real /models endpoint and instantly refresh the model_name dropdown with available models, then use the outputs downstream.

LLMHelper POST /models/unload

• Sends an unload request to llama-server when running in router mode, freeing the model from memory.
