# Cursor

> Connect ePhone AI to Cursor to use GPT, Claude, DeepSeek, and other models for AI-assisted coding.

[Cursor](https://cursor.sh) is a VS Code-based AI coding IDE with built-in AI chat, code completion, and code generation.

## Setup Steps

<Steps>
  <Step title="Open Cursor Settings">
    Press `Cmd/Ctrl + Shift + J` in Cursor, or go to **File → Preferences → Cursor Settings**.
  </Step>

  <Step title="Go to the Models Tab">
    In the settings panel, click the **Models** tab on the left. Scroll down to the **OpenAI API Key** section.
  </Step>

  <Step title="Enter Your API Credentials">
    * **OpenAI API Key**: Enter your ePhone AI API key (starts with `sk-`)
    * **Override OpenAI Base URL**: Enter `https://api.ephone.ai/v1`

    Click **Verify** to confirm the connection.
  </Step>

  <Step title="Add or Select Models">
    In the Models list, type any model name supported by the platform — for example `gpt-4o`, `deepseek-r1`, or `claude-opus-4-5-20251101`.
  </Step>
</Steps>

## Notes

<Warning>
  Cursor's third-party API mode currently only supports the **Chat feature**. Cursor Tab (inline completions) and Agent mode require an official Cursor subscription.
</Warning>

* Enter the full model name directly, e.g. `claude-opus-4-5-20251101`
* For the best stability, set your token's provider to `Official` or `Enterprise` in the ePhone AI console
* If a model appears unavailable, verify that it's included in your token's allowed model list
