Frequently Asked Questions about AI Terminology
What is the difference between AI and Machine Learning?
Artificial Intelligence (AI) is the broader concept of machines being able to carry out tasks in a way that we would consider “smart.” Machine Learning (ML) is a subset of AI where machines learn from data to improve at tasks without being explicitly programmed. In other words, all machine learning is AI, but not all AI is machine learning.
What is an LLM and how does it work?
A Large Language Model (LLM) is an AI system trained on vast amounts of text data to understand and generate human-like language. LLMs work by predicting the most likely next word (or token) in a sequence based on patterns learned during training. They use neural networks with billions of parameters and can perform tasks like writing, translation, answering questions, and even coding.
What are AI agents and how are they different from chatbots?
AI agents are autonomous systems that can perceive their environment, make decisions, and take actions to achieve goals without constant human input. Unlike traditional chatbots that simply respond to queries, agents can initiate actions, use tools, access external systems, and work independently over time. For example, an AI agent might not just answer questions about scheduling—it can actually check calendars, send invites, and reschedule conflicts.
