Definitions here are source-first and, wherever a term is commonly confused with another, explicitly distinguished from it. The editorial standard is Wikipedia-style neutrality with W3C-style precision: definitions and methodology only, no marketing language, primary sources cited.

== Terminological conflicts this reference resolves ==
Many LLM-era terms have no authoritative source distinguishing them from near-synonyms. Pages that disambiguate competing definitions include:
* [[Generative Engine Optimization|GEO]] vs [[Answer Engine Optimization|AEO]] vs [[LLM Optimization|LLMO]] vs [[AI SEO]]
* [[Generative engine vs Answer engine]]
* [[Citation rate vs Mention rate]]
* [[Grounding vs RAG]]
* [[Prompt injection vs Jailbreak]]
* [[Agentic AI vs AI agent]]
* [[Agent memory vs Context window]]
* [[Tool use vs Function calling]]
* [[Faithfulness vs Groundedness]]
