Optimizing AI Performance

Learn how to get the most out of Cursor's AI capabilities while maintaining high performance and following industry best practices.

Key Optimization Areas

  • Prompt Efficiency: Write effective prompts that get better results faster
  • Context Management: Provide the right amount of context without overwhelming the AI
  • Model Selection: Choose the right AI model for your specific needs
  • Workflow Optimization: Streamline your development process

Prompt Optimization Techniques

Efficient Prompt Structure

TEXT
Effective prompt structure:

1. CONTEXT: Brief background information
2. TASK: Clear, specific instruction
3. CONSTRAINTS: Any limitations or requirements
4. FORMAT: Desired output format
5. EXAMPLES: Reference examples if helpful

Example:
"Context: I'm building a React component for user authentication.
Task: Create a login form with email and password fields.
Constraints: Use TypeScript, include validation, and follow Material-UI patterns.
Format: Complete functional component with proper types.
Example: Similar to our existing UserProfile component."

Context Optimization

✅ Good Context

  • • Relevant file references
  • • Specific function/component names
  • • Current project structure
  • • Technology stack details

❌ Avoid

  • • Entire codebase dumps
  • • Irrelevant file contents
  • • Too much historical context
  • • Vague references

AI Model Selection

Choosing the Right Model

GPT-4 (Recommended for Complex Tasks)

Best For:
  • • Complex code generation
  • • Architecture decisions
  • • Debugging complex issues
  • • Code refactoring
Performance:
  • • Higher accuracy
  • • Better context understanding
  • • More detailed responses
  • • Slower but more thorough

GPT-3.5 Turbo (Good for Simple Tasks)

Best For:
  • • Quick code completions
  • • Simple refactoring
  • • Basic explanations
  • • Rapid prototyping
Performance:
  • • Faster responses
  • • Lower cost
  • • Good for simple tasks
  • • Less context awareness

Model Configuration

settings.json - Model Configuration

JSON
{
  "cursor.ai.model": "gpt-4",
  "cursor.ai.temperature": 0.1,
  "cursor.ai.maxTokens": 4000,
  "cursor.ai.systemMessage": "You are an expert software developer. Provide clear, concise, and accurate solutions.",
  "cursor.ai.includeCodeContext": true,
  "cursor.ai.includeFileContext": true
}

Workflow Optimization

Efficient Development Patterns

1

Start with Structure

Ask AI to create the basic structure first, then iterate

2

Iterative Refinement

Use follow-up prompts to improve and add features

3

Batch Similar Tasks

Group related requests to maintain context

Context Management

TEXT
Effective context management strategies:

1. Use file references instead of pasting entire files
   "Looking at the UserService.ts file, add error handling to the login method"

2. Provide relevant imports and dependencies
   "Using the existing API client from /lib/api, create a new endpoint"

3. Reference existing patterns
   "Following the same pattern as the ProductCard component, create a UserCard"

4. Include specific constraints
   "Using TypeScript and following our existing naming conventions"

Performance Monitoring

Tracking AI Usage

  • Monitor response times and quality
  • Track which prompts work best
  • Identify patterns in successful interactions
  • Adjust model settings based on performance

Optimization Metrics

Response Time

Track how quickly AI responds

Accuracy

Measure code quality and correctness

Efficiency

Iterations needed to get desired result

Industry Best Practices

Code Quality Standards

  • Always review AI-generated code before committing
  • Use AI to generate tests for your code
  • Maintain consistent coding standards across the team
  • Document complex AI-generated logic

Security Considerations

  • Never share sensitive data in AI prompts
  • Review AI suggestions for security vulnerabilities
  • Use AI to identify potential security issues
  • Follow secure coding practices in AI-generated code

Team Collaboration

  • Share effective prompts with your team
  • Document AI-assisted workflows
  • Use consistent AI model settings
  • Regularly review and update AI configurations

Common Issues & Solutions

Performance Issues

Slow AI Responses

If AI is responding slowly:

  • Check your internet connection
  • Try using GPT-3.5 for simpler tasks
  • Reduce the amount of context in prompts
  • Restart Cursor if issues persist

Poor Code Quality

If AI generates low-quality code:

  • Provide more specific requirements
  • Include better examples in prompts
  • Use GPT-4 for complex tasks
  • Break down complex requests into smaller parts
