The webpage presents a concise course titled “ChatGPT Prompt Engineering for Developers”. This course is designed to teach learners how to leverage large language models (LLMs) like ChatGPT to build innovative applications using the OpenAI API. It begins by explaining the fundamental principles and architecture of LLMs, and how they generate natural language from prompts. The course then delves into the best practices for prompt engineering, sharing techniques and strategies for crafting effective prompts that yield the desired responses from LLMs. This includes methods such as few-shot learning, priming, and data curation. The course also explores the various applications of LLM APIs for different natural language processing tasks, including inferring, transforming, and generating text. Finally, it provides a step-by-step guide, complete with code, on how to build a simple chatbot that can engage users in conversation on a specific topic using the OpenAI API.
