A Gentle Introduction to Model Distillation

Quick take

Model distillation is a technique that compresses a large AI model into a smaller, faster, and more efficient version while preserving most of its accuracy. Originally used to shrink deep learning models for resource-limited environments, it has evolved to handle the complexity of large language models (LLMs). Instead of training a new model from scratch, distillation transfers knowledge from a “teacher” model to a smaller “student,” reducing computational needs and speeding up inference.

Why it matters

For businesses and builders relying on LLMs, distillation lowers costs by enabling deployment on less powerful hardware or decreasing cloud usage without a steep performance hit. It addresses the growing challenge of running massive models in real time, which can be slow and expensive. Distilled models also improve latency, supporting smoother user interactions in applications like chatbots or assistants. However, the process can introduce accuracy trade-offs and requires careful tuning to balance efficiency with reliability. Understanding distillation helps operators decide when to invest in compression techniques versus scaling up infrastructure.
