The premise
Defaulting to the biggest model wastes money and latency; small models excel at classification, extraction, routing, and reformatting at a fraction of the cost.
What AI does well here
Identify small-model-friendly task patterns
Show the cost and latency delta
Recommend a 'small first, escalate' router
Note where small models genuinely fail
What AI cannot do
Replace evals on your specific data
Predict where small-model quality cliffs sit
