The language is the problem.

AI literacy doesn't mean learning more words. It means understanding which ones matter, which ones mislead, and which ones you can safely ignore. Glossairy clarifies AI language so teams can think clearly, communicate honestly, and make better decisions.

Use this word — it's clear and useful Know this word — useful with context Avoid this word — it misleads or confuses

What AI actually does

Model

Software trained on data to recognize patterns and generate outputs. The core building block of modern AI.

Also: language model, LLM, foundation model

Prompt

The input you give a model — a question, instruction, or example — to get a useful output back.

Training

The process of teaching a model by exposing it to large amounts of data. Happens before you ever use it.

Also: pre-training

Fine-tuning

Additional training on a narrower dataset to make a model better at a specific task or domain.

Token

A chunk of text — roughly a word or part of a word — that models read and generate one at a time.

Context window

The amount of text a model can consider at once. Bigger windows mean more information in, but not always better answers out.

Inference

When a trained model generates an output. Every time you use ChatGPT, that's inference.

Neural network

The technical architecture behind most AI models. Accurate but rarely useful in general conversation — it obscures more than it clarifies.

Also: deep learning, transformer, architecture

Parameters

The internal settings a model learns during training. Often cited as a size metric (e.g., "70 billion parameters") but meaningless to most audiences.

How teams use it

Agent

Software that can take actions on your behalf — not just answer questions, but do things: schedule, send, look up, file.

Also: agentic, AI agent, virtual worker

Automation

Using software to handle repeatable tasks without manual effort. Not new, but AI makes it possible for less structured work.

Workflow

A sequence of steps that gets something done. AI plugs into workflows — it doesn't replace them.

Integration

Connecting one tool to another so data flows between them. The plumbing that makes AI useful in practice.

Also: API, connector, plugin

RAG

Retrieval-augmented generation. A way to give a model access to your own documents so it answers from your data, not just its training.

Also: retrieval, grounding, knowledge base

Embedding

A way to represent text as numbers so software can compare meaning — used for search, recommendations, and clustering.

Also: vector, semantic search

Copilot

A branded metaphor that's become generic. Vague enough to mean anything from autocomplete to a full AI assistant.

Also: AI assistant, AI companion

How people talk about it

Hallucination

When a model confidently generates something that isn't true. Important to understand because it's the default failure mode, not a rare bug.

Also: confabulation

Bias

Patterns in training data that lead to skewed, unfair, or unrepresentative outputs. A real and measurable problem.

Alignment

The effort to make AI behave in ways humans intend. Important concept, but often used loosely to mean very different things.

Also: safety, guardrails, RLHF

Open source / open weight

Models whose code or weights are publicly available. "Open source" is often used loosely — open weights is more precise.

Also: Llama, Mistral, open model

AGI

Artificial general intelligence. A hypothetical future AI that can do anything a human can. Speculative, undefined, and used more for fundraising than clarity.

Also: superintelligence, strong AI

Sentient

Having feelings or awareness. No current AI system is sentient. Using this word about AI actively undermines credibility.

Also: conscious, alive, thinking

Singularity

A hypothetical point where AI surpasses human intelligence and accelerates beyond control. Science fiction, not strategy.

Reasoning

Models can produce outputs that look like reasoning. Whether they actually reason is an open debate. Using this word uncritically overstates what's happening.

Also: thinking, understanding, chain-of-thought

Clearer words. Better decisions.

Use Glossairy as a shared reference for your team — for clearer thinking, better narratives, and more effective go-to-market conversations.
