Cursor

Cursor Configuration

Cursor is the most popular AI code editor, deeply integrating AI capabilities based on VS Code, with support for custom OpenAI API endpoints.

Method 1: Settings UI Recommended

1. Open Cursor → go to Settings → Models
2. Find the OpenAI API Key field and enter:

sk-xxxxxxxxxxxx

3. Click Override OpenAI Base URL and enter:

https://betarouter.com/v1

4. Check the models you want to use (e.g. gpt-4o, claude-sonnet-4-20250514)
5. Click the Verify button to test the connection

Tip

If the model you need is not in the list, click + Add Model to add it manually.

Method 2: Environment Variables

Add environment variables to your shell config file:

~/.zshrc

export OPENAI_API_KEY="sk-xxxxxxxxxxxx"
export OPENAI_BASE_URL="https://betarouter.com/v1"

Reload and restart Cursor:

source ~/.zshrc

Note

Environment variables affect all programs that read them. If you only want to configure Cursor, Method 1 is recommended.

Verify Configuration

After configuring, open a file in Cursor and press Cmd + L (macOS) or Ctrl + L (Windows/Linux) to open the Chat panel and send a message to test.
