ComfyUI Extension: comfyui-prompt-enhancer

Ollama Prompt Enhancer

A crazy node that pragmatically just enhances a given prompt with various descriptions in the hope that the image quality just increase and prompting just gets easier.

Hints

This node requires an N-th amount of VRAM based on loaded LLM on top of stable diffusion or flux. <br> Since ollama keeps a given model loaded via olama run <model> as long the instance is running.

So for example using SD1.5 ~ 5GB VRAM + Mistral:3B uses around 16 GB VRAM (this is just predicted on my system under windows). <br> Have to be careful when loading too many models since it overloads the vram and you must probably quit ollama and restart the instance. <br> Ollama must be running or else the node will not be found / visible when starting comfyui.

Features:

• Simple node, just enter text and go
  • INPUT: CLIP
  • FIELD:
    • model (this is the model liste loaded from ollama)
    • positive text (llm enhanced from selected model)
    • negative text (llm enhanced from selected model)
  • OUTPUT:
    • ENHANCED_PROMPT
    • NEGATIVE_PROMPT (atleast what the llm determines, the one selected)
    • ORIGINAL_PROMPT

Installation

You need to have ollama installed from https://ollama.com before continue.<br> When within your custom python environment go to the custom_nodes/comfyui-prompt-enhancer folder and install via pip install -r requirements requirements.txt. <br>If you feeling lucky you can also install via pip install ollama That should be it.
