AI agent — An AI system that doesn't just answer once but works toward a goal in a loop — taking actions, reading the results, and deciding what to do next.
tool use — A model's ability to call external functions — run code, search the web, edit files — instead of only generating text.
open weights — A model whose trained parameters are published for anyone to download and run — unlike API-only models you can access but never possess.
