ComfyUI Ollama Description

ComfyUI Ollama integrates custom nodes into ComfyUI workflows, leveraging the Ollama Python client to seamlessly incorporate the capabilities of large language models (LLMs).

ComfyUI Ollama Introduction

The comfyui-ollama extension is a powerful tool designed to integrate the capabilities of large language models (LLMs) into the ComfyUI environment. This extension allows AI artists to leverage advanced language models for various creative and experimental purposes. Whether you want to generate text based on prompts, analyze images, or fine-tune parameters for specific tasks, comfyui-ollama makes it easy to incorporate these functionalities into your workflows.

By using this extension, you can enhance your creative projects with the intelligence of LLMs, enabling more sophisticated text generation, image analysis, and context-aware processing. This can be particularly useful for tasks such as generating creative writing, automating content creation, or experimenting with AI-driven art.

How ComfyUI Ollama Works

At its core, comfyui-ollama works by providing custom nodes within the ComfyUI framework that interact with the Ollama server. These nodes allow you to send prompts to the language models and receive generated responses, which can then be used in various parts of your workflow.

Think of it as having a smart assistant that you can ask questions or give tasks to, and it will provide you with intelligent responses based on the input you provide. For example, you can input a text prompt, and the model will generate a continuation or a relevant response. Similarly, you can input an image, and the model can analyze and describe it.

The extension requires a running Ollama server that is accessible from the host running ComfyUI. This server handles the heavy lifting of processing the prompts and generating responses using the language models.

ComfyUI Ollama Features


The OllamaVision node allows you to query input images. This means you can input an image, and the model will analyze it and provide a description or other relevant information. This feature is particularly useful for tasks that involve image recognition or analysis.

Example Use Case:

  • Input an image of a painting, and the model can describe the scene, identify objects, or even suggest a title for the artwork.


The OllamaGenerate node enables you to query a language model using a given text prompt. This node is ideal for generating text based on specific inputs, such as writing prompts, dialogue generation, or content creation.

Example Use Case:

  • Provide a prompt like "Once upon a time in a distant land," and the model will generate a continuation of the story.


The OllamaGenerateAdvance node offers advanced querying capabilities with fine-tuned parameters and the ability to preserve context for generating chained responses. This node is useful for more complex tasks that require maintaining context across multiple interactions.

Example Use Case:

  • Create a chatbot that can hold a conversation, remembering previous interactions and responding accordingly.

ComfyUI Ollama Models

The extension supports various models available through the Ollama library. Each model has different capabilities and is suited for different tasks. Here are some examples:

  • Llama 3: A versatile model suitable for general-purpose text generation.
  • Phi 3 Mini: A smaller model that is faster and requires less memory, ideal for quick tasks.
  • Gemma: A model designed for creative writing and storytelling.
  • LLaVA: A model with vision capabilities, useful for image analysis tasks. Example Use Case:
  • Use Llama 3 for generating detailed and coherent text, while using LLaVA for tasks that involve both text and image inputs.

Troubleshooting ComfyUI Ollama

Here are some common issues you might encounter while using the extension and how to resolve them:

Common Issues and Solutions

  1. Ollama Server Not Reachable
  • Solution: Ensure that the Ollama server is running and accessible from the host running ComfyUI. Check your network settings and firewall configurations.
  1. Model Not Responding
  • Solution: Verify that the model is correctly loaded and available on the Ollama server. You can check the server logs for any errors or issues.
  1. Incorrect or Unexpected Outputs
  • Solution: Review the input prompts and parameters. Sometimes, tweaking the prompt or adjusting the parameters can lead to better results.

Frequently Asked Questions

  • Q: How do I install the extension?
  • A: Follow the installation instructions provided in the original readme or use the ComfyUI manager to install via the git URL.
  • Q: Can I use multiple models in a single workflow?
  • A: Yes, you can use different nodes with different models in the same workflow to achieve more complex tasks.
