What AI Is

Artificial Intelligence (AI) refers to computer software designed to perform tasks that typically require human intelligence, such as recognizing images, making decisions, or processing human language.

What a Large Language Model Is

A Large Language Model (LLM) is the foundational technology powering conversational tools.

  • Think of an LLM as a hyper-advanced predictive text generator.
  • It was built by reading billions of pages of human-written text.
  • It works by calculating probabilities to guess what word should logically come next based on your text input.

What an AI Assistant Is

An AI assistant is a specific application built on top of an LLM to serve as a user interface. Tools like ChatGPT, Claude, Gemini and for those wanting to use Windows, Copilot are AI assistants. They are designed to follow instructions, maintain conversational memory, and help you complete digital tasks.

What an AI Agent Is

An AI agent is software that uses an LLM as its “brain” but has the added capability to act autonomously. While an assistant waits for your command at every step, an agent is given a broad goal and can plan steps, use external software tools, browse the web, and execute a sequence of actions independently to accomplish that goal.

Common Myths and Misconceptions

  • Myth: AI is sentient and understands things like a human.
    • Reality: AI does not have feelings, beliefs, consciousness, or lived experiences. It mathematically processes text patterns without experiencing actual understanding.
  • Myth: AI is always factually accurate.
    • Reality: AI can generate realistic-sounding falsehoods, commonly referred to as “hallucinations.” Always double-check critical facts.
  • Myth: AI knows what you mean automatically.
    • Reality: AI cannot read your mind. It responds strictly to the explicit text you type. Poor input leads directly to poor output.
