Wondering how Claude AI works? Simply put, Claude is a large language model built by Anthropic that generates responses by predicting the most relevant next token based on your input, guided by a unique safety framework called Constitutional AI. Unlike most AI tools that are trained purely on human feedback, Claude is shaped by a set of written principles that influence how it reasons, responds, and avoids harm. In this guide, you get the full technical story, explained in plain language.
What Kind of AI Is Claude?
Claude is not a search engine, a chatbot script, or a simple autocomplete tool. It is a large language model, and that distinction changes everything about how it thinks and responds.
Large Language Models
A large language model is a neural network trained on massive amounts of text. It learns statistical patterns across billions of words and uses those patterns to generate human-like responses. Claude processes your input as tokens (chunks of text), runs them through layers of a transformer neural network, and outputs the most contextually appropriate response. The model does not retrieve answers from a database. It generates them.
