What is Large Language Model (LLM)?
A Large Language Model (LLM) is an AI system trained on vast amounts of text to understand and generate human language, powering tools like Claude and ChatGPT.
LLMs predict the most likely next piece of text given everything before it, which lets them write, summarise, translate, answer questions and reason through problems.
Knowing how an LLM works — its strengths, its tendency to sometimes sound confident while being wrong — is the foundation of using AI well, and it's where every kenai program starts.
