Building Applications with the ChatGPT API

Artificial intelligence is transforming how we build software, but integrating these capabilities into real-world projects requires more than just basic API calls. To build reliable, production-ready systems, you need to understand how to structure your prompts, handle structured data, and manage API limitations effectively. This text-based course guides you through the fundamentals of connecting to the ChatGPT API, structuring your queries for reliable outputs, and designing robust AI-powered applications. You will learn the mechanics behind large language models and how to leverage them systematically within your existing codebase. What you'll learn: - Understand the foundational architecture of large language models and how APIs process text. - Configure API connections and manage key parameters like temperature and token limits. - Apply advanced prompt engineering techniques to ensure predictable, structured JSON outputs. - Design stateful conversational interfaces by managing chat history and context windows. - Explore modern integration patterns including Retrieval-Augmented Generation (RAG) basics. - Implement error handling, rate limiting, and secure API key management in your code. You will start with core terminology and API authentication before progressing to structured prompts, context management, and practical application architectures. Designed for developers, engineers, and technical makers who want to build with AI, this course requires no prior experience with machine learning.
