A model that can take actions, not just produce text.
A language model given a set of tools it may call, allowed to loop: decide, act, look at the result, decide again. The important design question is not accuracy but blast radius: what the worst wrong action can reach.

Work done after the response is sent.
Work moved out of the request so the user is not left waiting: sending email, processing an upload, generating a report. Requires somewhere to report progress and somewhere to report failure.
Whether the mail you send reaches an inbox at all.
Sending is your side of it; delivering is the receiving provider’s decision, taken in a fraction of a second on the strength of what your domain says about you. Nothing in your code reports a failure here, which is why it is normally discovered by somebody who never got their password reset.

Announcing that something will be removed.
Marking a field or endpoint as going away while still supporting it, so callers have time to move. Only meaningful if you can measure who is still using it.

Reading every row to answer one question.
What the database resorts to when no index supports your query. Instant with ten rows, catastrophic with ten million, which is why this problem never appears during development.
Which program on a machine you are talking to.
A number that lets one machine run many servers at once. The address finds the machine, the port finds the program: a web app on 3000, a database on 5432.
A question asked of the database.
A request for data. Cheap when an index supports it, ruinous when it forces a scan of every row. Which questions you ask should be a design decision, not an accident.

Letting a model call functions you define.
Giving a model a set of actions it may take: search, fetch, create. Turns a text generator into something that affects the world, which makes what you grant far more important than how well it reasons.
