token — The chunk of text a model reads and writes in — roughly three-quarters of a word — and the unit AI usage is billed in.
model routing — Sending each request to a model chosen by the difficulty of the task, rather than using one model for everything.
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.
