Wiktionary examples

These source excerpts show how LLM appears in context. They illustrate usage; the definition above remains the entry’s reference meaning.

  1. Some skeptics argue that the software is capable only of blind mimicry — that it’s imitating the syntactic patterns of human language but is incapable of generating its own ideas or making complex decisions, a fundamental limitation that will keep the L.L.M. approach from ever maturing into anything resembling human intelligence.
  2. Currently, large language models (LLM) are the base model for creating more specific natural language producers, like chatbots or personal assistants. BERT, GPT-3, and other LLM can be used to program all kinds of “semantic machines”, to create machines for almost any kind of linguistic purpose.
