Answer in one sentence

Choosing an AI model is a multi-objective decision, not a benchmark leaderboard exercise.

Quality

Record task-specific metrics, evaluation scenarios, and failure categories.

Reliability

Track invalid outputs, timeouts, formatting failures, and edge-case behavior.

Operations

Compare latency, memory, deployment complexity, and infrastructure cost.

Decision record

Write why the selected model won and what evidence would trigger a future change.
