Glossary

People who sell AI to a business often speak a language of their own: tokens, agents, RAG, fine-tuning, hallucinations. This glossary translates those words for the people who have to decide, not for those who write the code.

Each entry starts with a one-sentence definition, then shows the word at work in a small or medium-sized business and ends with the mistakes we see most often when a company meets it for the first time. The entries are grouped by topic, and below you will also find all of them in alphabetical order. They point to one another: if a word leads you to another, follow the link.

When an entry quotes a figure, the source sits next to it. If a term someone used in a meeting is missing and you did not follow, write to us: it is the best way for us to know which entry to add.
