ChatGPT Master Course
A complete 156-lesson journey from absolute beginner to professional platform engineer covering every ChatGPT surface: chat.openai.com, GPT-5, DALL-E image generation, Custom GPTs, GPT Store, Canvas, Code Interpreter, the OpenAI API, and beyond.
What This Course Is
ChatGPT is OpenAI's AI assistant and the world's most popular AI chatbot. It spans multiple surfaces: the consumer chat at chatgpt.com, DALL-E image generation, Custom GPTs (specialized AI assistants), the GPT Store, Canvas (collaborative editing), Code Interpreter (Python execution), and the OpenAI API for developers. GPT-5 represents the latest generation with improved reasoning, multimodal capabilities, and deeper integration across the OpenAI ecosystem.
This course takes you from "I just tried ChatGPT" all the way to "I architect production platforms powered by the OpenAI API." Every lesson explains why the topic matters, walks through how it works, gives a real-world example, surfaces common mistakes, and ends with an exercise plus an optional professional challenge.
The curriculum tracks ChatGPT's current state as of August 2026: GPT-5 family (GPT-5, GPT-5 mini), DALL-E 3, Custom GPTs, GPT Store, Canvas, Code Interpreter, OpenAI API (chat completions, function calling, vision, structured outputs), and enterprise features. Where product behavior is version-sensitive, lessons carry a Last verified: YYYY-MM-DD stamp.
