ComfyUI Ollama

Custom ComfyUI Nodes for interacting with Ollama using the ollama python client.

Integrate the power of LLMs into ComfyUI workflows easily or just experiment with LLM inference.

To use this properly, you would need a running Ollama server reachable from the host that is running ComfyUI.
