AI Foundations

Artificial Intelligence

Technology that enables software to perform tasks that normally require human judgment, recognition, prediction or decision-making.

AI Foundations

Generative AI

AI that creates new content — such as text, images, audio, video or code — based on patterns learned from existing data.

Models & Knowledge

Large Language Model

LLM

A type of AI model trained on large amounts of text so it can understand and generate human-like language.

Agents & Automation

AI Agent

An AI system that can work toward a goal, make decisions and take actions using tools, data or connected systems.

Agents & Automation

Agentic AI

An approach where AI can plan and carry out multi-step work with a degree of autonomy instead of only answering one prompt at a time.

Building with AI

Prompt Engineering

The practice of giving AI clear instructions, context and constraints so it produces more useful and reliable results.

Models & Knowledge

Retrieval-Augmented Generation

RAG

A method that lets an AI model retrieve relevant information from a trusted knowledge source before generating its answer.

Agents & Automation

Workflow Automation

Using technology to move repetitive tasks and information through a process automatically, with people involved where needed.

Models & Knowledge

Knowledge Assistant

An AI assistant designed to answer questions using an organization’s approved documents, information and knowledge sources.

Models & Knowledge

Vector Database

A database designed to store and search information by meaning and similarity rather than only exact words or traditional fields.

Responsible AI

Human-in-the-Loop

A design approach where people review, approve or guide important steps instead of leaving every decision entirely to AI.

Responsible AI

AI Governance

The rules, responsibilities and controls that guide how AI is selected, used, monitored and managed inside an organization.

AI Foundations

AI Assistant

An AI application that helps a person with tasks such as finding information, drafting or reviewing work.

Agents & Automation

AI Automation

Automation that uses AI for a step requiring interpretation, generation or a prediction within a defined workflow.

Agents & Automation

Multi-Agent System

A system in which multiple AI agents coordinate, divide responsibilities or pass work to one another.

Building with AI

Tool Calling

A model’s request to use a defined function or tool, with execution controlled by the surrounding application.

Building with AI

Model Context Protocol (MCP)

MCP

A protocol for exchanging tools and context between compatible AI applications and servers.

Responsible AI

AI Readiness

The practical conditions an organization needs to use AI for a particular task responsibly and effectively.

Responsible AI

AI Evaluation

A structured way to check whether an AI system’s outputs and actions meet defined requirements for its intended task.
