A language model with relatively few parameters, optimized for speed, cost, or on-device deployment.
Friendly Description: A Small Language Model is a more compact version of an AI language model, designed to be fast, cheap, and able to run in places where a giant model can't, like directly on your phone or laptop. It might not know quite as much as the largest models, but for many everyday tasks it's plenty smart, with the bonus of speed and privacy.
Example: A note-taking app might use an SLM that lives on your device to summarize meetings instantly, without sending anything to the cloud. It's not as powerful as a 100-billion parameter model, but it gets the job done quickly, works offline, and keeps your notes private.
