A beginner-friendly walkthrough of building an AI-powered article summarizer using Python and the OpenAI API. Covers installing the openai package, securely storing API keys as environment variables, making your first chat completions API call, parsing the response object, handling rate limit and billing errors, accepting user input interactively, and chunking long articles to stay within token limits. The result is a working CLI tool that summarizes any pasted text.
