The article discusses prompt engineering, which is the process of creating inputs that determine the output generated by an AI language model. High-quality prompts can result in better output while poorly defined prompts can lead to inaccurate or negative responses. The article explains that AI language models rely on deep learning algorithms and natural language processing (NLP) to fully understand human language. There are two main learning methods for language models: supervised and unsupervised learning. The article also covers prompt categories, which include information-seeking prompts and instruction-based prompts
