Everyone is talking about AI, but not everyone understands what AI is. AI, or artificial intelligence, refers to technology that enables machines to perform tasks that traditionally required human thinking—things like reading, writing, analyzing information, and making decisions.

A particularly powerful form of AI today is the large language model (or LLM), which is a type of AI trained on vast amounts of text that allows it to understand and generate human language, making it the engine behind popular tools like chatbots and AI writing assistants. Think ChatGPT or Google Gemini.
