## Executive Summary
Fine-tuning teaches a small search agent your tools and environment, giving it the reliability of a frontier model at lower latency and cost.

## Why It Matters (Strategic Analysis)
Traditional supervised fine-tuning and single-turn reinforcement learning fail to capture the interdependent, multi-step sequential dependencies required by autonomous search agents. Multi-turn reinforcement learning solves this architectural gap by directly optimizing entire decision trajectories against final outcome rewards, making specialized smaller models viable alternatives to expensive frontier systems.
