Demystifying AI Terms

The AI Glossary for Decision-Makers. Without Buzzwords.

LLM, RAG, agents? Here I translate the technical jargon into tangible descriptions. Briefly explained what it means – and why it is important for your company.

If you are choosing a system

LLM, RAG, agent or Agentic AI? Start with the decision guide first.

The glossary defines the terms. The guide shows which system makes sense in which scenario.

Agentic AI (Multi-Agent Systems)

What it means:

A team of specialized AI agents, each taking on a specific role (e.g., researcher, writer, quality checker) and working together on a large project.

Why this is important for you:

The highest evolutionary stage for automating entire business processes. Ideal for massive, complex projects that would normally require a human team.

AI Agent

What it means:

An AI assistant that breaks tasks into multiple steps, independently operates tools (web search, calculator, CRM), and adjusts plans until the goal is achieved.

Why this is important for you:

The step from chatbot to automation. An agent can conduct research, compile data, and take on complex tasks. It remembers previous steps.

Copilot

What it means:

An AI assistant that is directly integrated into existing software (like Microsoft 365, Teams, or development environments) and assists the user.

Why this is important for you:

Supports employees in their daily work right where it happens, without having to switch between different tools.

Corporate LLM

What it means:

An internal instance of a language model (e.g., powered by Microsoft Azure) that is completely shielded from the public internet.

Why this is important for you:

Ensures full data protection and GDPR compliance. Your company and customer data never flow into the training of public models.

Generative AI (GenAI)

What it means:

The umbrella term for all AI systems that can create new content (texts, images, code, or speech) – as opposed to classical AI, which only analyzes data.

Why this is important for you:

The technology that suddenly makes automation tangible for SMEs because it understands language and unstructured data (like free-flowing text in emails).

Guardrails

What it means:

Well-defined safety rules and system boundaries within which an AI is allowed to operate. They prevent an AI from deviating from the topic, giving unwanted answers, or performing unsafe actions.

Why this is important for you:

Your insurance against "AI accidents." Guardrails ensure that your AI (e.g., in customer support) always acts professionally, does not promise imaginary prices, and strictly adheres to your company policies.

Hallucination

What it means:

When an AI invents plausible-sounding but factually incorrect information because it lacks specific knowledge.

Why this is important for you:

The biggest risk in business use. Reduced to nearly zero through good setup (like RAG) and clear guardrails.

Hyperscaler

What it means:

Gigantic cloud providers like Microsoft (Azure), Google, or AWS that operate the massive data centers for AI models.

Why this is important for you:

They provide the raw power. For tailored SME solutions (like RAG bots), consultants build on their secure infrastructure without becoming dependent on ready-made, rigid "out-of-the-box" licenses.

LLM (Large Language Model)

What it means:

A pure, intelligent text generator. You ask a question, it generates the answer based on its learned world knowledge (e.g., ChatGPT).

Why this is important for you:

Ideal for quick text creation, idea generation, or fast explanations. Operates autonomously without connection to external systems and does not access current company documents.

Prompt Engineering

What it means:

The art of giving the AI precise and context-rich instructions (prompts) so that the result is immediately usable.

Why this is important for you:

Those who give the AI vague tasks receive vague results. With well-formulated system prompts, the AI works like a well-instructed employee.

RAG (Retrieval-Augmented Generation)

What it means:

A method where the AI specifically searches in a predefined database (your company documents) before formulating an answer.

Why this is important for you:

Prevents fabricated answers. The AI uses only your approved knowledge (e.g., PDFs, guidelines). Perfect for company knowledge databases and reliable internal systems.

TCO (Total Cost of Ownership)

What it means:

The "true total costs" of an IT solution. Not just the monthly license or API price, but also implementation, maintenance, internal training, and operation.

Why this is important for you:

The most important KPI in AI procurement: An open-source model may not have a license fee, but can be significantly more expensive in operation and maintenance (high TCO) than the API call of a paid hyperscaler model.
