# Anthropic Claude Partner Nodes ComfyUI Official Example

> This article will introduce how to use Anthropic Claude Partner nodes in ComfyUI to complete conversational functions

Anthropic Claude is a family of powerful AI models known for strong reasoning, safety, and long-context capabilities. ComfyUI has integrated the Anthropic Claude API through Partner Nodes, allowing you to use Claude directly in your workflows for conversational and image analysis tasks.

In this guide, we will walk you through using the Anthropic Claude node in ComfyUI.

<Tip>
  To use the Partner Nodes, you need to ensure that you are logged in properly and using a permitted network environment. Please refer to the [Partner Nodes Overview](/tutorials/partner-nodes/overview) section of the documentation to understand the specific requirements for using the Partner Nodes.

    <Tab title="Portable or self deployed users">
      Make sure your ComfyUI is updated.

      * [Download ComfyUI](https://www.comfy.org/download)
      * [Update Guide](/installation/update_comfyui)

      Workflows in this guide can be found in the [Workflow Templates](/interface/features/template).
      If you can't find them in the template, your ComfyUI may be outdated. (Desktop version's update will delay sometime)

      If nodes are missing when loading a workflow, possible reasons:

      1. You are not using the latest ComfyUI version (Nightly version)
      2. Some nodes failed to import at startup
    </Tab>

    <Tab title="Desktop or Cloud users">
      * The Desktop is base on ComfyUI stable release, it will auto-update when there is a new Desktop stable release available.
      * [Cloud](https://cloud.comfy.org) will update after ComfyUI stable release.

      So, if you find any core node missing in this document, it might be because the new core nodes have not yet been released in the latest stable version. Please wait for the next stable release.

## Supported Models

| Model          | Strengths                                                                                                                                                          |
| -------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| **Opus 4.7**   | Anthropic's most capable model. Step-change improvement in agentic coding, complex reasoning, and nuanced analysis. 1M context window. Knowledge cutoff: Jan 2026. |
| **Opus 4.6**   | Previous generation flagship with strong all-around performance. 1M context window.                                                                                |
| **Sonnet 4.6** | Best balance of speed and intelligence for most workloads. 1M context window. Fast latency.                                                                        |
| **Sonnet 4.5** | Fast and capable, good for everyday tasks. 200k context window.                                                                                                    |
| **Haiku 4.5**  | Fastest and most cost-effective option for simple queries and high-throughput use cases. 200k context window.                                                      |

All models support both text-only and multimodal (text + image) inputs with up to 20 images per request.

  Open in Comfy Cloud

<Card title="Download Workflow" icon="download" href="https://github.com/Comfy-Org/workflow_templates/blob/main/templates/api_anthropic_claude.json">
  Download JSON or search "Anthropic Claude" in Template Library
</Card>

<Note>
  In the corresponding template, we have built a prompt for analyzing and generating role prompts, used to interpret your images into corresponding drawing prompts.
</Note>

Refer to the numbered steps in the workflow image to complete the basic workflow execution:

1. In the `Load Image` node, load the image you need AI to interpret (optional — skip for text-only queries)
2. In the `Anthropic Claude` node, modify `prompt` to set your conversation prompt, or change `model` to select a different Claude model
3. (Optional) Set the `system_prompt` to define the model's behavioral instructions
4. Click `Run` or press `Ctrl(cmd) + Enter` to execute the conversation
5. After the API returns results, view the AI response in the `Preview Any` node

### Additional Notes

* Adjust `max_tokens` (up to 32000) and `temperature` (0.0 to 1.0) in the node's advanced options
* The `seed` parameter controls whether the node re-runs — results are non-deterministic regardless of seed value
