ComfyUI Ollama is a custom node designed for the ComfyUI workflow, utilizing the ollama Python client, which enables users to easily incorporate Large Language Models (LLMs) into their workflows or simply conduct GPT experiments. The primary advantage of this plugin is its ability to interact with the Ollama server, allowing users to perform image queries, prompt LLMs with given prompts, and query LLMs with fine-tuned parameters while maintaining the context of the generation chain.
