Definition

A Small Language Model (SLM) is a smaller model designed to use fewer parameters and resources than a large language model.

The advantage of a smaller model can include:

  • Lower inference cost
  • Faster responses
  • Easier deployment
  • More focused specialization
  • Greater suitability for company-specific or task-specific applications

A company may not need a massive general-purpose model for every use case. A smaller model trained or adapted for a narrow task can sometimes provide a more practical solution.

Why It Matters

Quantization and SLMs help you reason about latency, hosting, and inference cost — the levers that decide whether an AI feature is actually affordable to run.
