# Automate Sovereign AI Workflows with Meliai in n8n

> Connect Meliai to n8n using the OpenAI Chat Model node. Set your API key and base URL once, then use any Meliai model in your n8n AI workflows.

n8n's OpenAI Chat Model node supports custom base URLs, which means you can point it at Meliai and immediately use any of Meliai's 60+ models in your automated workflows — no custom code required. Configure your credentials once, and every AI node in your n8n instance can route inference through sovereign European infrastructure.

<Steps>
  <Step title="Add an OpenAI Chat Model node">
    Open your workflow in n8n and add an **OpenAI Chat Model** node. You'll find it in the node panel under **AI → Language Models**.
  </Step>

  <Step title="Create new OpenAI credentials">
    In the node's credential selector, choose **Create new credential** and fill in the following fields:

    | Field        | Value                      |
    | ------------ | -------------------------- |
    | **API Key**  | Your `sk-mel-...` key      |
    | **Base URL** | `https://api.meliai.ai/v1` |

    Save the credential — you can reuse it across all OpenAI-compatible nodes in your instance.
  </Step>

  <Step title="Enter your model ID">
    In the **Model** field of the Chat Model node, type the Meliai model ID you want to use. You can find available model IDs in the [models reference](/api-reference/models).
  </Step>

  <Step title="Connect to an AI Agent or Chain node">
    Wire the Chat Model node into an **AI Agent**, **Basic LLM Chain**, or any other AI orchestration node in your workflow. The Chat Model node acts as the language model backend for whichever orchestrator you choose.
  </Step>

  <Step title="Test and activate your workflow">
    Use **Execute Workflow** to run a test with sample input. Once the output looks correct, toggle the workflow to **Active** so it runs on your configured trigger.
  </Step>
</Steps>

<Note>
  All n8n AI features work with Meliai through the OpenAI-compatible endpoint — including **AI Agent**, **Basic LLM Chain**, **Summarization Chain**, **Question and Answer Chain**, and **Information Extractor**. Any node that accepts an OpenAI Chat Model credential will work.
</Note>

<Tip>
  Append a routing suffix to the model ID in the Model field — for example, `<MODEL_ID>:eco` — to control how Meliai selects a provider for that node. Useful when you want to optimise different workflow branches for cost, speed, or carbon footprint independently.
