Building Generative AI Applications with OpenAI APIs

Integrating artificial intelligence into software is no longer a futuristic luxury—it is a core requirement for modern developers. This course provides a clear, text-based pathway to understanding and implementing generative AI models in your own applications. You will transition from a curious developer to an AI-integrator capable of leveraging powerful language models. By studying foundational concepts and analyzing structured code examples, you will learn how to connect external tools, manage context, and deploy intelligent features safely. What you'll learn: Understand the foundational mechanics of large language models, prompt engineering, and token management; Implement OpenAI APIs to generate text, manage chat completions, and control model parameters; Apply function calling to connect language models with external database queries and APIs; Build intelligent assistants using structured context, system instructions, and state management; Explore embeddings and vector search fundamentals to implement Retrieval-Augmented Generation (RAG) patterns; Manage common production challenges such as rate limits, cost optimization, and basic LLMOps best practices. The journey begins with essential terminology and the core mechanics of API communication. From there, you will progress through structured text-based lessons detailing advanced integration techniques, practical code patterns, and architectural workflows. This course is designed for software developers, product builders, and technology enthusiasts who are new to AI integration. No prior experience with machine learning or AI models is required, though a basic understanding of programming concepts will help you get the most out of the code examples.
