## Executive Summary
How Specializing the Vocabulary of SLMs Can Cut Inference Cost by 77% in Real Applications.

## Why It Matters (Strategic Analysis)
General-purpose tokenizers force domain-specific SLMs to execute wasteful matrix multiplications across tens of thousands of inactive tokens while fragmenting repetitive structural syntax. Eliminating this overhead at the tokenizer stage unlocks substantial inference cost reductions without requiring modifications to underlying model parameters.
