LLM (Large Language Model)
A Large Language Model (LLM) is the language model behind AI assistants like ChatGPT or Gemini: trained on vast amounts of text, it generates answers in natural language. How it represents your business depends on how machine-readable your foundation is.
A Large Language Model – LLM for short – is the technology at the core of modern AI assistants like ChatGPT, Gemini or Perplexity. It was trained on enormous amounts of text and learned to predict patterns in language. From this comes the ability to answer questions, write texts and explain connections – in natural language, without hard-coded rules.
For you as a business, the key point is this: an LLM “knows” nothing about you except what it can infer from available sources. The clearer and more machine-readable your digital foundation is, the more reliably a model represents your business – and the less it guesses.
LLMs rarely work alone. For current answers they combine their training knowledge with passages retrieved live. Anyone who wants to be visible to these models makes sure their own facts are clean, structured and up to date.

Frequently asked questions.
How does an AI read my website — and what does that mean for my content?
An AI doesn't read your website top to bottom; it breaks it into individual text passages and, at the moment of the question, retrieves only the fitting ones (Retrieval-Augmented Generation, RAG). What matters is therefore not the whole page, but whether individual passages answer a concrete question on their own and machine-readably. Content loaded only via script or buried in long prose often doesn't reach the AI.
Does the AI do everything on its own?
No. The AI helps with maintenance — translating, meta texts, image descriptions, checks. Strategy and signature come from us — and you.
