Glossary: Key Terms Explained
Plain-English definitions for the jargon you'll encounter.
LLM
Large Language Model. The AI "brain" behind most chat tools. Examples: GPT-4, Claude 3, Gemini. They predict and generate text based on your input.
Model
The specific version of an AI. Claude Sonnet vs. Opus, GPT-4o vs. GPT-3.5. Bigger models = more capable but slower and costlier.
Prompt
The instruction or question you type to the AI. Better prompts = better results. Think of it as how you talk to the tool.
API
Application Programming Interface. A way for developers to connect AI models directly into their own apps or workflows. Requires coding or automation tools.
Token
How AI measures text. Roughly 1 token = 1 word (or part of a word). API costs are often charged per token used. More tokens = more cost.
Context Window
How much text the AI can "see" and remember at once in one conversation. Claude and Gemini lead here with 100K–1M token windows.
MCP
Model Context Protocol. A standard that lets AI connect to external tools and services — like your Google Drive, Slack, or ad accounts — so it can read and act on real data.
Agent / Agentic AI
An AI that doesn't just answer questions — it takes actions. Agents can browse the web, write files, click buttons, or complete multi-step tasks on your behalf.
Computer Use
A capability that lets an AI see and control a computer screen — clicking, typing, navigating — as if it were a human at the keyboard.
Skill / System Prompt
Hidden instructions that tell an AI how to behave before you ever type a message. Used to give AI a role, set rules, or load context automatically.
Temperature
A setting that controls how "creative" vs. "precise" the AI is. Low temperature = consistent, factual. High temperature = more surprising, varied output.
Hallucination
When an AI makes up something that sounds plausible but isn't true. All LLMs do this. Always verify important facts, especially with ChatGPT and older models.
RAG
Retrieval-Augmented Generation. A technique where AI pulls from your own documents or database before answering — reducing hallucinations. NotebookLM uses this.
Fine-tuning
Training an existing AI model on your own data to make it better at your specific tasks. Requires technical setup. Usually done via API.
Multimodal
An AI that can work with more than just text — images, audio, video, documents. ChatGPT, Claude, and Gemini are all multimodal.
