Yes, 100% free. No sign-up, no credit card. All modules, lessons, and quizzes are immediately accessible. Progress saves locally in your browser.
The course covers ChatGPT essentials, Advanced Data Analysis, Custom GPT creation, API integration, the Assistants API, and advanced reasoning models like o1.
No prerequisites required for the first modules (ChatGPT and Custom GPTs). The later modules on the API and Assistants API require basic programming knowledge, particularly in JavaScript or Python.
The Assistants API allows you to build stateful AI agents with persistent threads, removing the need to manage conversation history manually. It also supports tools like File Search (RAG) and Code Interpreter.
Unlike standard models that generate tokens immediately, reasoning models generate a hidden chain of thought first, allowing them to solve complex math, coding, and logic problems with much higher accuracy.
