Today in Compute College

Lesson & Term of the Day

Today's lesson

Agent loops, stopping conditions, and budgets

Control repeated model and tool steps with explicit limits, progress checks, and cost budgets. Why it matters today: Today's lesson connects the AI Engineering track to the compute market readers are watching.

Term of the Day

Agent loop

An agent loop is the repeated cycle of choosing a next step, using a tool, and checking what happened. The cycle needs a stopping rule so the system knows when the task is done or should be handed back. A research assistant searches, reads a page, and decides whether it has enough evidence or needs another search.
