What is an LLM?
A Large Language Model (LLM) is an AI model trained on enormous amounts of text. It can understand and generate human-like text in response to any prompt. LLMs power ChatGPT, Google Gemini, Claude, and most modern AI assistants.
What is a Large Language Model?
A Large Language Model (LLM) is an AI model with three key characteristics:
- 1Large: it has billions of parameters (internal settings) trained on enormous amounts of data.
- 2Language: it works with text - understanding text input and generating text output.
- 3Model: it is a mathematical system that represents learned patterns from training data.
LLMs are trained on text from books, websites, scientific papers, code, and more. After training, they can answer questions, write content, translate languages, summarize documents, write code, and complete almost any text-based task.
