Lesson & Term of the Day
Term of the Day
Small language model
A small language model is a smaller AI model designed to run with lower cost, lower latency, or more control than frontier models. Smaller models may be good enough for narrow tasks, classification, extraction, or on-device use. They can reduce dependence on expensive serving infrastructure.
