I Finally Built My First AI App (And It Wasn’t What I Expected)

A beginner-friendly tutorial walks through building a first AI application, an article summarizer using the OpenAI API. The guide covers setting up a Python environment, installing the necessary library, and making an API call to a model like gpt-4o-mini. It emphasizes real-world engineering practices, such as securely managing API keys with environment variables to prevent accidental exposure. The process of structuring the API request and parsing the response is explained in detail, and the author shares a practical troubleshooting experience with a RateLimitError to highlight the difference between code issues and infrastructure setup.
