API Setup & Authentication

Start with OpenAI API key. Implement secure key management using environment variables. Use the official OpenAI Python or Node.js SDK.

Cost Optimization

GPT-3.5-turbo costs 0.5¢ per 1K tokens (input) and 1.5¢ per 1K tokens (output). Implement caching and batching to reduce costs by 60%.

Common Use Cases

- Customer support chatbots (70% cost reduction) - Content generation and summarization - Document analysis and extraction - Code generation and debugging - Sales assistant and lead qualification

Security Best Practices

- Never expose API keys in frontend code - Implement rate limiting (10 requests/second) - Sanitize user inputs to prevent prompt injection - Log all API calls for compliance - Monitor costs daily

Performance Optimization

Use GPT-3.5-turbo for most tasks (10x cheaper than GPT-4). Reserve GPT-4 for complex reasoning. Implement async calls to prevent blocking.
