# Iro AI — AI Glossary

> Plain-language definitions for the AI terms you'll meet in Iro AI lessons, in this site, and in everyday AI work.

**Canonical glossary:** https://tryiro.com/glossary
**Last updated:** 2026-05-24

## Core AI terms

**AI fluency** — The practical ability to use, evaluate, and direct AI tools effectively for real tasks.

**LLM (large language model)** — A model trained on large amounts of text that can generate text, answer questions, summarize, translate, and more. Examples: GPT-5, Claude, Gemini.

**Generative AI** — AI systems that produce new content (text, images, audio, video, code) instead of only classifying or scoring existing data.

**Prompt** — The instruction or question you give an AI model. Better prompts produce better outputs.

**Prompt engineering** — The discipline of writing, structuring, and refining prompts so that AI models reliably produce useful output.

**Context window** — How much text a model can read at once. Larger windows let the model consider longer documents and conversations.

**Token** — The basic unit of text a model reads and writes. Roughly equivalent to a word fragment.

**Temperature** — A setting that controls how varied an AI's output is. Lower values are more predictable; higher values are more creative.

**System prompt** — A high-priority instruction set at the start of a conversation that shapes how the AI behaves.

## Models and tools

**ChatGPT** — OpenAI's consumer AI assistant. Includes a free tier and paid tiers with access to more capable models.

**Claude** — Anthropic's AI assistant. Known for long context windows and careful reasoning.

**Gemini** — Google's AI assistant, integrated across Google products.

**Perplexity** — An AI-powered answer engine that grounds responses in live web search results.

**Copilot** — Microsoft's AI assistant family, including GitHub Copilot for coding.

**Cursor** — An AI-first code editor that integrates LLMs deeply into the writing-and-editing flow.

**Midjourney / DALL·E / Stable Diffusion / Imagen / Flux** — AI image-generation models, each with different strengths in style, photorealism, and editability.

## Failure modes

**Hallucination** — When an AI confidently produces wrong information that sounds correct. Detecting hallucinations is a core Iro AI skill.

**Confabulation** — Same idea as hallucination — invented details that look reasonable but are not grounded in source data.

**Prompt injection** — A security issue where untrusted content embedded in inputs tries to override the AI's instructions.

**Jailbreak** — A prompt designed to bypass an AI's safety constraints. Iro AI teaches awareness, not exploitation.

## Workflows

**Agent** — An AI system that pursues a goal across multiple steps, often using tools, memory, or external data.

**Workflow automation** — Stringing AI actions together to automate a repeatable process.

**RAG (retrieval-augmented generation)** — A pattern where the AI is given relevant documents at runtime so its answers are grounded in current data.

**Vibe coding** — Casual term for AI-assisted, prompt-led software building. The skill is judgment: knowing what to ask, what to verify, and what to throw away.

## Iro AI terms

**Prompt Lab** — Iro's active prompt-practice feature. You write prompts and get AI-generated feedback on quality and effectiveness.

**Live duels** — ELO-ranked 5-question speed rounds against bot opponents in cyberpunk arenas with battle music and podium reveals.

**Track** — One of four high-level groupings (Tool Mastery, Creative & Coding, Work & Career, Core Skills).

**Path** — A single learning path within a track. Iro has 18 paths.

**Rank tier** — The 6-step progression system: Bronze, Silver, Gold, Platinum, Diamond, Iridescent.

**Streak** — Consecutive-day usage counter that supports habit formation.

**XP** — Experience points earned by completing lessons, exercises, and duels.

**AI IQ test** — Iro's free 10-question quiz at https://tryiro.com/quiz that ranks users Bronze-to-Iridescent and recommends a starting path.
