AI (Artificial Intelligence)
Software that learns patterns from lots of information so it can answer questions or do tasks.
LLM (Large Language Model)
The "brain" behind chat tools; it's read enormous amounts of text and predicts helpful words.
Prompt
What you type to the AI. Your instruction or question.
Hallucination
When AI confidently gives a wrong answer. Always double-check important facts.
Agent
An AI that doesn't just answer, but actually does the task for you, start to finish.
Token
A small chunk of text (roughly a word-part) that AI reads and counts.
Chatbot
An AI that talks with you — you type a question, it types an answer. It advises but doesn't act.
Pattern-matcher
The simplest honest description of today's AI: it finds patterns in what it's read and predicts what comes next.
Model
The trained software itself — the thing that has "studied" the data and can now answer questions.
Training data
The books, articles, and web pages an AI studied to learn its patterns.
Deepfake
A fake video or audio clip made by AI, often imitating a real person's face or voice.
Inference
The moment the AI generates an answer from your prompt — the "thinking" part, even though it's really just calculating.
