The massive collection of text, images, or audio used to teach an AI system how to perform its tasks.
MEDIUMTransformer
A breakthrough AI architecture invented in 2017 that allows computers to understand the context of entire sentences at once.
LOWFor Consumers
Anthropomorphism
The human tendency to treat AI as if it has feelings, consciousness, or a personality, even though it is just math.
LOWAutocomplete
A feature that predicts the rest of a word or sentence you are typing based on common language patterns.

An AI system that suggests products, content, or services to you based on your past behavior and preferences.
LOWSmall Language Model
A compact, highly efficient AI model designed to run directly on phones or laptops without needing an internet connection.
LOWVoice Assistant
A digital helper that understands spoken commands and can answer questions or control smart devices.
LOWVoice-to-Voice AI
AI systems that listen to your spoken words and instantly reply with a highly realistic, emotive synthetic voice.
MEDIUMFor Creators
Copyright Infringement
The legal controversy over AI companies using artists' and writers' copyrighted work to train AI without permission or pay.
MEDIUMFew-Shot Learning
A prompting technique where you give the AI two or three examples of what you want before asking it to do the task.
LOWJailbreak
A clever technique used by humans to trick an AI into breaking its own safety rules and generating forbidden content.
MEDIUMOpen Source AI
AI models where the underlying code and instructions are made publicly available for anyone to use, study, or modify for free.
LOWOpen Weights
A type of AI release where the trained model is available to download, but the original training data and code are kept secret.
LOWPrompt Engineering
The skill of writing clear, specific instructions to get the best possible results from an AI tool.
LOWText-to-Image
A type of generative AI that creates original pictures and artwork based on a written description.

LOWZero-Shot Learning
When an AI successfully performs a task it has never explicitly been trained or given an example to do.
LOWFor Professionals
AI Agent
An advanced AI system that can make decisions, use software tools, and take actions on its own to achieve a goal.
