Large Language Model
Also called: LLM
A model trained on huge amounts of text to predict the next token, which turns out to be enough to write, summarise, translate, and reason.
An LLM is a transformer trained at scale on text, with a deceptively simple objective: guess what comes next. Do that well enough across trillions of tokens and behaviours like summarising, translating, and following instructions emerge without being taught explicitly. Post-training then shapes the raw model into something that follows instructions safely.
In practice: GPT-5.6, Claude, Gemini and Llama are all LLMs, differing in training, size, and tuning.
