Cursor — Grok Code & Editors

Cursor: The Native AI Editor

Cursor is a code editor built on VS Code that integrates AI directly into its interface. Unlike Cline, which is an extension, Cursor is a standalone editor with built-in AI features: inline completion, contextual chat, and multi-file edits.

Grok configuration in Cursor

Cursor supports custom models via the OpenAI API, allowing you to use grok-build-0.1 as the generation engine.

Configuration with grok-build-0.1

Step 1: Open Settings

Open Cursor settings:

macOS: Cmd+,
Windows/Linux: Ctrl+,

Navigate to the Models section.

Step 2: Configure API Key

In the API Keys subsection, enter your xAI API key.

Step 3: Set Base URL

In the “Override OpenAI Base URL” field, enter:

https://api.x.ai/v1

This field tells Cursor to send requests to the xAI server instead of OpenAI.

Step 4: Add the Model

In the model field, enter grok-build-0.1
Click “Add Custom Model”

The model now appears in the list of available models. You can select it from the Cursor chat model selector.

Step 5: Verify

Open the Cursor chat panel (Ctrl+L), select grok-build-0.1 from the model selector, and ask a question about your code.

Cursor Features with grok-build-0.1

Contextual Chat

Cursor chat automatically sends the open file and selected code as context. You can also add files with @:

“@package.json which dependencies are outdated?”

Composer (Multi-file)

Composer mode lets you edit multiple files in a single interaction. Cursor displays a diff for each modified file, which you can accept or reject individually.

Inline Completion (Tab)

Cursor Tab completion uses the configured model to suggest code as you type. With grok-build-0.1 speed, suggestions appear nearly instantly.

Cmd+K (Quick Edit)

Select code, press Cmd+K (or Ctrl+K), and describe the desired change. Cursor applies the change directly in the editor with a visual diff.

Cursor vs Cline

Aspect	Cursor	Cline
Type	Standalone editor	VS Code extension
Cost	Subscription + API	Free + API
Tab Completion	Built-in	No
Multi-file	Native Composer	Via agent
Customization	Limited	Open source

Both tools work well with grok-build-0.1. Cursor is more integrated; Cline is more flexible.
