AI Model

Fundamentals

The trained program that comes out of the machine-learning process - the thing that actually answers, predicts, or generates.

A model is the end product of training: a big file of learned numbers plus the code to use them. When you chat with an AI assistant, your text goes into a model and the reply comes out of it.Models come in many sizes and specialties. Some only classify email as spam or not spam. Others, like GPT or Claude, are huge general-purpose language models that can write, summarize, and reason across many topics.
