What this is
An LLM is a generative model specialized in language: drafting, summarizing, answering, rewriting tone. It predicts useful text; it does not guarantee truth.
Everyday example
When you type into ChatGPT, Claude, or Grok and get a written answer or draft, you are using an LLM — a model specialized in language.
An LLM is a large language model — AI specialized in reading and writing language.
- It predicts the next token, at scale, across a huge range of topics.
- That is why one tool can draft a contract clause and a campaign line.
- It is not a database and not a search engine, even when it sounds sure.
- ChatGPT, Claude, Gemini, and Grok are LLM products you already know.
Next action: Treat LLM output as language, not as a system of record, until you ground it.
What changes in how you lead
How decision rights, process, and ownership should change.
- Do not let an LLM be the only source of a number that will be decided on.
- Pair LLMs with retrieval or a human check for high-stakes facts.

Large Language Model (LLM) vs Frontier model
An LLM is a type of model. 'Frontier' describes capability tier — the newest, most capable general models. You can also buy smaller, cheaper LLMs that are not frontier.

Strengths: first drafts, summarization, extraction into structured formats, translation of tone.
Weaknesses: hallucinations, limited private knowledge unless connected to your systems, uneven specialized expertise.
ChatGPT, Claude, Gemini, and Grok are product experiences built on LLMs from different labs. Enterprise vs consumer versions differ on retention and controls — verify.
