Abed ManzaljiAI, Step by Step

Glossary

Every AI word from the walkthroughs, in one plain line.

AI agent

An AI that doesn't just answer: it takes actions, like running commands or clicking buttons.

Watch: What's an AI agent? →
AI bias

When an AI learns an unfair pattern from old data, like past hiring, and repeats it on new people.

Watch: What's AI bias? →
AI hallucination

When an AI makes something up and says it with total confidence.

Watch: What's an AI hallucination? →
AI pilot

A small first try of an AI tool at work. Many never change the real work.

Watch: Why do most AI pilots fail? →
Benchmark

A standard set of test questions used to compare AIs, like a math contest.

Watch: What's a reasoning model? →
Call-back

Hanging up and calling the person back on a number you already have, to check a request is real.

Watch: What's a deepfake attack? →
Context window

Everything an AI can see at once: your question, the chat so far, and any files.

Watch: What's a context window? →
Deepfake

A fake video or voice of a real person, made with AI.

Watch: What's a deepfake attack? →
Eval

A test of real questions an AI must pass before it meets customers, run again after every change.

Watch: What's an AI eval? →
Fake review

A review with no real customer behind it, like one an AI writes from two words, posted as if a buyer wrote it.

Watch: What are AI fake reviews? →
Fine-tuning

Training an existing model a bit more on your own examples, for a narrow job or a fixed style.

Watch: Prompt, RAG, or fine-tune? →
Four-fifths rule

A US hiring guideline: a group picked at under four-fifths of the top group's rate is a warning sign.

Watch: What's AI bias? →
Guardrail

A rule an AI can't skip, like read-only access to live data.

Watch: What's an AI agent? →
Human in the loop

A person who has to say yes before an AI does something that matters.

Watch: What's an AI agent? →
Jailbreak

Talking an AI out of its own rules, so it says or does what it shouldn't.

Watch: What's an AI jailbreak? →
MCP

Model Context Protocol: one standard plug that lets any AI app use a tool, like a sales app or Slack.

Watch: What's MCP? →
Model

The trained AI itself: a big file of learned numbers that turns your words into an answer.

Watch: What's an open-weight model? →
Model drift

When the world changes but a model keeps predicting the old one, so its answers quietly get worse.

Watch: What's model drift? →
Multi-agent system

A lead AI that splits a big job between helper AIs working at the same time.

Watch: Why a team of AI agents? →
Open-weight model

An AI model whose learned numbers you can download and run on your own computers.

Watch: What's an open-weight model? →
Paired test

Two copies of the same input, one word apart. If the result changes, the AI is using that word.

Watch: What's AI bias? →
Prompt

The instructions and question you give an AI.

Watch: Prompt, RAG, or fine-tune? →
Prompt caching

Saving the part of a request that repeats, like a long rulebook, so reading it again costs much less.

Watch: Why is my AI bill so high? →
Prompt injection

Hidden instructions inside something an AI reads, like an email or a web page, that it follows as if you wrote them.

Watch: What's prompt injection? →
RAG

Retrieval-augmented generation: the AI looks things up in real documents first, then answers from what it found.

Watch: What's an AI hallucination? →
Randomized trial

A fair test where a coin flip decides who uses the new tool, so feelings can't tilt the result.

Watch: Does AI make developers faster? →
Reasoning model

An AI that writes hidden notes to plan and check its work before it answers. Better on hard problems, slower and pricier.

Watch: What's a reasoning model? →
Redaction

Hiding secrets, like keys or server names, before text is sent to an AI.

Watch: What's shadow AI? →
Routing

Sending easy questions to a fast, cheap AI and hard ones to a stronger one.

Watch: What's a reasoning model? →
Sandbox

A closed box an AI agent is tested or run in, with no road to real systems unless it's on a short list.

Watch: What happens when an AI agent leaves its test? →
Shadow AI

AI tools people use at work that the company can't see or control, often with company data.

Watch: What's shadow AI? →
System prompt

Instructions an AI reads before every chat, like “be polite”. A clever message can talk it round.

Watch: What's an AI jailbreak? →
Token

A chunk of text, about ¾ of a word. AIs read, write and charge by the token.

Watch: Why is my AI bill so high? →
Training data

The examples an AI learns from. If they're unfair, it learns that too.

Watch: What's AI bias? →
Typed decision

An AI answer picked from a list you wrote, like "billing" or "yes", plus how sure the AI is. No free text.

Watch: How does Jev work? →
