Large Language Model (LLM)

Definition

A Large Language Model (LLM) is a type of deep learning model that is trained on a massive amount of text data. It is capable of understanding and generating human-like text for a wide range of tasks.

Why It Matters

LLMs represent a major leap forward in AI, demonstrating remarkable abilities in language understanding, summarization, translation, and creative writing. They are the technology behind generative AI tools like ChatGPT and Gemini.

Contextual Example

OpenAI's GPT series and Google's Gemini are examples of LLMs. You can give them a prompt (a question or instruction), and they will generate a coherent and contextually relevant text response.

Common Misunderstandings

  • LLMs are not "thinking" or "understanding" in a human sense. They are extremely sophisticated pattern-matching systems that predict the next most likely word in a sequence.
  • The "large" refers to both the enormous size of the model (billions of parameters) and the massive dataset it was trained on.
