Cursor is an AI-powered code editor that helps you write better code faster. It integrates with various AI models to provide smart completions, refactoring suggestions, and code explanations as you work.

• Install Cursor from cursor.sh
• Set up your OpenAI API key or other model provider keys
• Start coding with AI assistance and explore the features

Cursor supports a wide range of AI models from various providers. Here's a comprehensive list of compatible models:

Note: Model availability may change as providers update their offerings. You can add custom model names in Cursor's settings.

To configure which AI model Cursor uses:

1. Click on the settings icon in the bottom left corner
2. Select "AI" from the settings menu
3. Choose your preferred model from the dropdown
4. Enter any required API keys for the selected provider

System prompts are instructions that guide how AI models behave when assisting with your code. In Cursor, you can customize system prompts to:

• Make AI follow specific coding standards
• Specify preferred frameworks or libraries
• Set boundaries for AI responses
• Include project-specific context

To set a custom system prompt in Cursor:

1. Click on the settings icon in the bottom left corner
2. Select "AI" from the settings menu
3. Scroll to the "System Prompt" section
4. Edit the default prompt or add your custom instructions

A .cursorrules file is a powerful way to configure AI behavior for specific projects or repositories in Cursor. This file allows you to define project-specific AI settings that will be applied automatically when working within that project.

Creating a .cursorrules File

To create a .cursorrules file:

1. Create a new file named .cursorrules in your project root directory
2. Format the file using JSON syntax
3. Define your custom rules and settings

Example .cursorrules File

{
  "systemPrompt": "You are a helpful assistant that specializes in this project. Follow these guidelines:
- Use TypeScript for all new code
- Follow the repository's existing code style
- Use React functional components with hooks
- Document all functions with JSDoc comments",
  "defaultModel": "claude-3-opus",
  "excludeFromContext": [
    "node_modules/**",
    "build/**",
    "*.log"
  ],
  "includeInContext": [
    "src/**/*.ts",
    "src/**/*.tsx"
  ]
}

Key Configuration Options

• systemPrompt: Custom instructions for the AI when working in this project
• defaultModel: The preferred AI model to use for this project
• excludeFromContext: File patterns to exclude from AI context
• includeInContext: File patterns to prioritize in AI context
• aiCommand: Custom slash command configuration
• autoComplete: Settings for auto-completion behavior
