Agent
What is agent?
An agent is a system where a model plans and executes a sequence of tool calls toward a goal rather than answering in one turn. Reliability compounds across steps, which makes per-step accuracy far more consequential than it appears.
The arithmetic is unforgiving. Ninety-five per cent per step over ten steps is under sixty per cent end to end, and users judge the end-to-end number.
Fine-tuning on successful traces is one of the higher-return interventions available, because it improves the two things that break most often: argument formatting and call ordering.
