LLM
Also said as
large language modellanguage modelAI model
An LLM — large language model — is the text engine inside chatbots like ChatGPT and Claude: it predicts what words should come next, which is how it writes, summarizes, and answers.
Why it matters to your business
Knowing that a chatbot is prediction, not a database, explains every failure that matters: it can sound authoritative and still be wrong, because it's completing patterns, not looking up facts.
The catch · what vendors don't say
The chatbot is the product wrapper; the LLM is the engine underneath — which model you're getting changes quality more than which app you bought.
