# ChatBox with Global AI: Desktop and Mobile Setup

> Configure ChatBox on desktop and mobile to call GPT, Claude, and Gemini through Global AI with the platform URL and token.

ChatBox is a cross-platform graphical chat client that supports custom OpenAI and Anthropic compatible providers, so it connects to Global AI directly. This page walks through the full setup. The desktop and mobile flows are the same.

<Warning>
  Before you begin, complete the redemption and key steps in the [Integration overview](/en/clients/overview#before-you-integrate).
</Warning>

Download: [chatboxai.app](https://chatboxai.app)

## Configuration

<Steps>
  <Step title="Open Settings">
    Open ChatBox and click **Settings** in the lower left.
  </Step>

  <Step title="Choose a model provider">
    Open **Model Provider** and choose **Claude** (or OpenAI if you want GPT). Fill in:

    * **API Key**: paste your `sk-` token
    * **API Host**: `https://globalai.vip/v1`
    * **Path**: leave blank (default)
  </Step>

  <Step title="Add the latest models manually">
    ChatBox's built-in model list may not include the newest versions, so add them manually. Click **New**, paste the model ID from the [Pricing page](https://globalai.vip/pricing) (for example `claude-sonnet-5`) into **Model ID**, **check all capability options**, keep other defaults, and save.
  </Step>

  <Step title="Start chatting">
    Close settings, return to the home page, click **New chat**, choose the model you just added in the lower right, and send a message. A normal reply confirms the integration.
  </Step>
</Steps>

## Troubleshooting

<AccordionGroup>
  <Accordion title="401 / Unauthorized">
    The key was copied incompletely or with whitespace. Recopy from [/keys](https://globalai.vip/keys) and check.
  </Accordion>

  <Accordion title="Connection timeout or cannot connect">
    The most common cause is a proxy or circumvention tool. Turn them off and retry.
  </Accordion>

  <Accordion title="A model is not found">
    The model ID is misspelled, or the model is not allowed in your token's scope. Search for it on the [Pricing page](https://globalai.vip/pricing) to confirm the spelling.
  </Accordion>
