About this course

The ability to build intelligent applications using large language models is becoming an essential skill for modern software development. This course provides a clear path from understanding basic AI terminology to building functional Python applications that leverage the latest generative models. You will transition from a beginner to a developer capable of orchestrating AI-driven workflows. By reading through detailed technical explanations and practicing with provided code examples, you will gain the confidence to implement advanced features such as sentiment analysis, automated summarization, and intelligent search. What you'll learn: - Master prompt engineering techniques to get reliable, structured results from language models. - Configure Python environments and authentication for secure OpenAI API integration. - Build text-based applications using GPT-4o for complex reasoning and content generation. - Implement speech-to-text functionality using Whisper and programmatic image generation. - Apply text embeddings and vector search concepts to create recommendation systems. - Understand Retrieval-Augmented Generation (RAG) patterns for building data-aware AI. - Manage API costs and performance through token optimization and efficient request handling. The course begins with foundational definitions of generative AI and API structures before moving into practical implementation logic. You will explore how to connect different models to solve real-world problems, culminating in the ability to design sophisticated chatbots and data processing tools. This course is designed for beginners with basic Python knowledge who want to enter the world of AI development. No prior experience with machine learning or API development is required.
