The API is where real applications are built. This course is how you get there.This course is for developers who are ready to move from experimenting with AI to actually building with it. You'll work directly with OpenAI's modern Responses API — the one OpenAI recommends for all new projects — writing real code that connects to real tools and produces real results.WHAT YOU'LL BUILDYou'll complete Three Capstone Projects, each one closing out a module after the concepts that make it possible have been taught.Research Assistant — Decomposes complex questions into sub-questions, investigates each one independently, and synthesizes the findings into a structured answer. Built using instruction chaining, personas, and advanced few-shot techniques.Production Support Bot — A fully functional support chatbot with budget controls, sliding window context management, and response caching. Built incrementally across two modules to show how production systems are actually assembled — not just demonstrated in a single notebook.Multi-Tool Agent — Connects to a live weather API and queries a real SQLite database using function calling. This is AI that interacts with the outside world through Python functions.WHAT YOU'LL LEARNAPI Fundamentals — Connect to the OpenAI API, configure your environment, and make your first calls using the Responses API. Understand model selection, token usage, and cost tracking from day one.Core Prompting — Zero-shot, one-shot, and few-shot prompting. Understand exactly how the model responds to different prompt structures and why it matters.Production Prompting — Structured JSON outputs for reliable parsing, error handling with exponential backoff, reusable prompt templates, and systematic prompt eva

Welcome to this complete YAML course for beginners!If you’ve ever worked with tools like Ansible, Docker Compose, or Kubernetes, you’ve probably seen YAML files everywhere — but maybe they looked confusing or full of strange symbols. Don’t worry! This course will help you go from “What is YAML?” to “I can write and understand YAML like a pro!” — all in simple, clear English, made for non-native speakers.Let’s start with a bit of history. YAML stands for “YAML Ain’t Markup Language.” It was created in the early 2000s as a human-friendly alternative to XML and JSON. The idea was to make configuration files easy to read, write, and understand, even for people who aren’t programmers. Today, YAML is used everywhere — from Kubernetes manifests and Ansible playbooks to CI/CD pipelines and cloud infrastructure files. Knowing YAML is an essential skill for DevOps engineers, system administrators, and developers.In this course, you’ll begin by learning what YAML is, how it works, and why it’s used so widely in automation and configuration management. You’ll write your first YAML file, understand the syntax rules, and even parse YAML with Python to see how it works behind the scenes.Next, we’ll cover the basic YAML concepts — things like scalars, strings, multi-line text, comments, timestamps, and tags. You’ll learn to format your YAML correctly and make it more readable.Then, we’ll move on to advanced YAML features — such as sequences, ordered mappings, anchors, aliases, and multiple documents. These topics will help you handle complex configurations and reuse YAML efficiently.By the end of the course, you’ll not only understand YAML — you’ll be confident using
