Learn to build advanced AI agents from scratch. Start with OpenAI completions, progress to custom tools, Retrieval-Augmented Generation (RAG), and orchestrate multi-agent systems for real-world automation.
You'll build a simple AI assistant using the OpenAI Completions API, starting with basic prompt engineering and progressing to a simple chat loop. This course introduces the core concepts of completions, prompt design, and basic error handling.
You'll build your first AI agent using the OpenAI Agents SDK. This course introduces the core concepts of the Agents SDK, including Agents, and Runners. You'll learn how to create a simple agent with custom instructions and personality settings.
You'll master custom tool development and RAG by building a complete knowledge retrieval system using ChromaDB, creating custom tools that agents can call, and implementing the full function-calling workflow for enhanced agent capabilities.
You'll master more advanced techniques for building agents, including designing more complex tools, orchestrating agent collaboration, and creating a system where multiple agents work together to solve complex tasks.
I love that it's personalized. When I'm stuck, I don't have to hope my Google searches come out successful. The AI mentor Cosmo knows exactly what I need.

I'm really impressed by the AI tutor Cosmo's feedback about my code. It's honestly kind of insane to me that it's so targeted and specific.

I tried Leetcode but it was too disorganized. CodeSignal covers all the topics I'm interested in and is way more structured.
