AI glossary for leaders

The Jargon Decoder from inside the certifications, open to everyone.

34 terms in plain English, the words a leader actually meets when the room turns to AI. Each links to the module it first comes up in. Members get the same decoder one tap away inside every lesson.

Agent
AI that takes multi-step actions toward a goal you set (searching, writing files, using tools) instead of just answering a question. More powerful, and more in need of guardrails.

API
The plug through which your software calls someone else's AI. 'We use the API' means renting the model per use rather than owning infrastructure.

Where this comes up: Certified AI Leader, The AI Landscape for Business

Automation
Software doing a task end-to-end without a person. AI widened what's automatable; the leadership question is which steps still deserve human judgment.

Context window
How much material an AI can consider at once. Think of it as working memory. Bigger windows mean it can read your whole report; nothing outside the window exists for it.
Copilot
AI embedded inside a tool people already use (email, docs, CRM) as an assistant. The gentlest on-ramp for teams, and the easiest spend to lose track of.

Data readiness
Whether your data is accessible, clean, and permitted for the AI use you're planning. The unglamorous predictor of most AI project outcomes.

Where this comes up: Certified AI Leader, AI Strategy Foundations

Deepfake
AI-generated audio or video that convincingly imitates a real person. Good enough now that a familiar face or voice on a call is no longer verification; a callback on a channel you chose still is.
Deployment
A tool put into real daily use, as opposed to a pilot. The pilot is the test with a few people and an exit. The deployment is the thing your staff and customers now depend on, which is why it needs owners, a review step, and a way to switch it off.

EU AI Act
The European Union's AI law, phasing in from 2025 through 2028. It sorts AI uses into risk tiers with duties for each; anyone selling into or operating in the EU needs a view on it.

Fine-tuning
Training an existing AI model further on your own examples so it behaves more like you need. Expensive and usually unnecessary: most companies get further with better prompts and context.
GenAI
Generative AI: models that produce new text, images, code, or audio rather than just classifying existing data. The wave that made AI a board topic.

Where this comes up: Certified AI Leader, AI Strategy Foundations

Guardrails
The rules and controls that keep AI use safe: what data may go in, what decisions need a human, what the AI may never do. Guardrails are what let you say yes quickly.

Hallucination
When an AI states something false with total confidence. It is not a glitch. It is built into how these models work. The fix is process (verification, human review), not scolding the tool.

Human-in-the-loop
A workflow where AI drafts and a person approves before anything ships. The single most useful risk control you have: speed of AI, accountability of a human.

Where this comes up: Certified AI Leader, Thinking in AI

Inference
Running a trained model to get answers (as opposed to training it). Inference cost is the per-use bill, the number that scales with adoption.
ISO 42001
The international management-system standard for AI (ISO/IEC 42001): a documented cycle of policy, risk assessment, controls, and review. Certification is an audit you can buy; alignment is a truthful mapping of governance you already run.

Where this comes up: Certified Chief AI Leader, Governance, Ethics & Risk at Scale

LLM
Large Language Model: the engine behind tools like ChatGPT and Claude. It predicts the most likely next words, which makes it brilliant at drafting and summarizing, and capable of confidently making things up.

Where this comes up: Certified AI Leader, Working with AI as a Leader

Machine learning
Software that learns patterns from data instead of following hand-written rules. The umbrella over almost everything called AI today.

Where this comes up: Certified AI Leader, The AI Landscape for Business

Model
A trained AI system, the product of feeding enormous data through training. Different models trade off capability, speed, and price; picking one is a procurement decision, not a loyalty oath.

Where this comes up: Certified AI Leader, Thinking in AI

Model risk
The chance an AI system is wrong in ways that hurt: biased decisions, fabricated facts, drifting quality. Manage it like any other operational risk, with measurement, an owner, and a review cycle.

NIST AI RMF
The US National Institute of Standards and Technology's AI Risk Management Framework: free, voluntary, and organized into four functions, govern, map, measure, manage. Increasingly used as procurement shorthand, and in Texas as a statutory safe harbor.

Open-source model
A model whose weights you can download and run yourself. More control and privacy, more work. The alternative to renting intelligence through an API.
PII
Personally Identifiable Information: anything that can identify a person. The data category that decides whether an AI use needs privacy review before it needs enthusiasm.

Where this comes up: Certified AI Leader, AI Across the Business

Pilot
A deliberately small, time-boxed test of an AI use case with success criteria set in advance. The alternative to both paralysis and company-wide rollouts of the untested.

Where this comes up: Certified AI Leader, The AI Landscape for Business

Production
The live setting where real work happens, as opposed to a trial. "In production" means real customers, real money, and real consequences for a mistake. It has nothing to do with a factory or manufacturing output.

Where this comes up: Certified AI Leader, The AI Landscape for Business

Prompt
The instruction you give an AI. The quality of what you get back tracks the quality of the brief you give, exactly like delegating to a smart new hire.

RAG
Retrieval-Augmented Generation: letting an AI look things up in your documents before answering, so responses use your facts instead of its memory. The standard fix for 'the AI doesn't know our business.'

Where this comes up: Certified AI Leader, Thinking in AI

ROI
Return on investment. For AI: hours saved, revenue gained, or risk reduced, minus what it costs to run. Measured, not asserted in a vendor deck.

Where this comes up: Certified AI Leader, AI Strategy Foundations

shadow AI
Employees using AI tools nobody approved, with company data. Universal, mostly well-intentioned, and the first thing an AI use policy has to make safe rather than pretend to ban.

Where this comes up: Certified AI Leader, The AI Landscape for Business

Token
The unit AI vendors bill by, roughly three-quarters of a word. 'Cost per token' is why long documents and chatty automations have real, countable costs.

Where this comes up: Certified AI Leader, Thinking in AI

Training data
Everything a model learned from. It sets the model's knowledge cutoff and its blind spots. It is also why vendors get asked 'was our data used to train this?'
Use case
One specific job AI does for the business: 'summarize support tickets,' not 'do AI.' Strategy is choosing a few high-value use cases and finishing them.

Where this comes up: Certified AI Leader, AI Strategy Foundations

Vendor lock-in
When leaving a supplier becomes too expensive because your data, workflows, or prompts are trapped in their product. Avoided by asking exit questions before signing.

Where this comes up: Certified AI Leader, Thinking in AI

Workslop
AI-generated work output polished enough to pass along and empty enough to push the real work onto whoever receives it. Named in 2025 research; the cost lands on the receiver, and the reputational cost lands on the sender.
