    Small Language Models, Big Leverage

    Reaching for the largest frontier model by default is an expensive habit. For a growing share of enterprise workloads, a small, fine-tuned language model wins on the metrics that actually matter in production: cost, latency, privacy and control.

    Where SLMs win

    Narrow, high-volume tasks — classification, extraction, routing, structured generation — rarely need a trillion parameters. A focused SLM, tuned on your data, can match or beat a frontier model on the task while running an order of magnitude cheaper and faster.

    A simple decision framework

    • Task breadth: open-ended reasoning leans frontier; bounded, repeatable tasks lean SLM.
    • Volume & latency: high request volume or strict latency budgets favour a small local model.
    • Data sensitivity: when data cannot leave your perimeter, a self-hosted SLM is often the only compliant option.
    • Control: fine-tuning gives you predictable, versionable behaviour you own.

    The pragmatic answer is usually a blend — frontier models for hard reasoning, SLMs for the high-volume core — orchestrated behind one interface.
