AI vocabulary gets confusing fast because the same words show up in product demos, startup decks, engineering docs, creator tutorials, and social posts — often without clear definitions. This glossary is built to fix that.

Use the search box to jump straight to a term, or browse the glossary letter by letter. Every entry includes a plain-English definition and a short example so the terms are useful in practice, not just technically correct.

How to use this glossary

Search by acronym, full term, or related wording. If you've seen something like T2T, VLM, GPT, prompt injection, RAG, or RLHF and want the fast explanation, start here.
