# Vercel AI Gateway

> Set up Coreply with Vercel AI Gateway to route requests to upstream providers through one endpoint.

AI Gateway is a routing layer. You still choose an upstream model from another provider, such as OpenAI or Google.

## Setup

<Steps>
  <Step title="Create a gateway key">
    Create an AI Gateway key, or use a Vercel access token if that is how your gateway is configured.
  </Step>

  <Step title="Choose Vercel AI Gateway in the app">
    Open Coreply and choose **Vercel AI Gateway** under **API Provider**.
  </Step>

  <Step title="Enter your settings">
    Fill in the following values:

    | Field           | Value                                                                                       |
    | --------------- | ------------------------------------------------------------------------------------------- |
    | API key         | Your AI Gateway key or Vercel access token                                                  |
    | Model           | A namespaced upstream model such as `openai/gpt-5.6-luna` or `google/gemini-3.5-flash-lite` |
    | Team ID or slug | Optional                                                                                    |
  </Step>

  <Step title="Configure the upstream provider options">
    Use the upstream provider namespace in **Provider Options**. For example:

    ```json theme={null}
    {"openai": {"reasoningEffort": "none"}}
    ```

    or

    ```json theme={null}
    {"google": {"thinkingConfig": {"thinkingLevel": "minimal"}}}
    ```
  </Step>
</Steps>

<Tip>
  **Model** must use the provider-prefixed format that AI Gateway expects, such as `openai/...` or `google/...`.
