Short, clear definitions of the terms you’ll come across in our courses.
Artificial intelligence (AI)

Generative AI
AI that can create new content (text, images, code) from a prompt. Conversational assistants are the best-known example.

LLM (large language model)
A type of model specialized in language, able to understand and generate text.
Business intelligence (BI)
The discipline of turning data into decision-ready information through dashboards and metrics.
DAX
