LLM (Large Language Model)
Also known as: Large Language Model, Foundation Model
In one sentence
A type of AI trained on massive amounts of text data to understand, generate, and reason about human language. LLMs power chatbots, writing tools, coding assistants, and many other applications.
Explain like I'm 12
Imagine someone who read every book, website, and article ever written, and now they can have conversations, write essays, and answer questions about almost anything—that's roughly what an LLM does.
In context
LLMs like GPT-4, Claude, Gemini, and LLaMA are the technology behind most AI tools people use today. They work by predicting the most likely next word in a sequence, but this simple mechanism produces remarkably sophisticated results—from drafting emails to explaining quantum physics to writing working code. Companies access LLMs through APIs (paying per token) or run open-source models on their own servers for privacy and cost control.
