Watch: OpenAI Codex Full Tutorial — Build AI Apps Live in 90 Minutes

Arsh Goyal’s latest tutorial walks you through OpenAI Codex from complete scratch, showing how to build a competitive programming practice generator in just 90 minutes. This is perfect if you’ve heard about Codex but never actually used it. No prerequisites needed, though basic Python knowledge helps. You’ll watch a real-world project come together live, which means you see the actual mistakes and problem-solving process, not just a polished final product. The tutorial covers everything from API setup to deploying your first AI-powered application.

Arsh Goyal’s channel stands out because he builds things, not just explains concepts. His content bridges the gap between theory and practice. He doesn’t waste time on corporate-style intros or lengthy explanations. Instead, he jumps into code and builds functional tools you can understand and replicate. This approach teaches you how developers actually think when integrating AI into real applications. If you’ve been frustrated by tutorials that are all talk and no code, this is the antidote.

After watching, you’ll understand how Codex interprets natural language and turns it into working code. You’ll know exactly how to connect the OpenAI API to your own projects. Most importantly, you’ll see that building an AI application isn’t some mysterious process reserved for AI experts. You could build a similar tool for your own domain, whether that’s education, automation, or data processing. The 90-minute format means you can watch it once and reference it while building your own projects.

Bottom line: If you want to stop reading about AI integration and actually see it happen in real time, this tutorial is essential viewing for developers at any skill level.
