## Key takeaways

- Hallucination is the term for confidently incorrect output — always verify facts.
- A prompt is an instruction; better inputs produce better listings.
- GEO is search optimization aimed at AI answer engines.
- Virtual staging and photo enhancement are different things with different rules.

## Core model terms

- LLM (large language model): the system that generates text from your instruction.
- Prompt: the instruction and context you give the model.
- Token: the unit of text models process; longer inputs cost more.
- Context window: how much text a model can consider at once.
- Hallucination: output that is fluent but factually wrong.
- Temperature: how varied versus predictable the output is.
- Fine-tuning: training a model further on specific examples.
- System prompt: hidden instructions that set the assistant's behavior.

## Real estate application terms

- Photo enhancement: correcting exposure, color and clarity on real photos.
- Virtual staging: digitally adding furniture to a vacant room.
- Virtual renovation: rendering a changed finish or layout — always disclose.
- AVM (automated valuation model): an algorithmic price estimate, not a CMA.

## Search and visibility terms

- Crawlability: how easily search bots can reach and read your pages.

## FAQ

### What does hallucination mean in AI?

It describes output that sounds authoritative but is factually incorrect. In real estate this is why every AI-generated number, date or property claim must be verified before publishing.

### What is GEO in AI search?

Generative engine optimization — structuring content so AI answer engines like ChatGPT, Google AI Overviews and Perplexity can extract and cite it accurately.
