LLM (Large Language Model)

The kind of AI behind Claude, ChatGPT, and Gemini. A model trained to predict text, which makes it good at writing, coding, and reasoning over language.

What it is

An LLM, or large language model, is the type of AI that powers tools like Claude, ChatGPT, and Gemini. It was trained on a huge amount of text and learned to predict what comes next. That simple-sounding skill, scaled up, lets it write, summarize, translate, answer questions, and generate code.

Simple analogy

Think of an extremely well-read assistant who has read most of the public internet but remembers it as patterns, not as exact pages. It is brilliant at producing fluent, plausible text, and it has no built-in way to know when it is wrong.

Why this matters for designers

When you prompt Claude to build a component or critique a layout, you are talking to an LLM. Understanding that it predicts rather than looks things up explains both its strengths (fast, flexible, creative) and its weak spots (it can sound confident while being wrong). You get better results by giving it good context and checking its output, not by trusting it blindly.
