GEO Glossary · 76 terms

Generative Engine Optimization (GEO) is the work of making an AI system such as ChatGPT, Gemini or Google AI Overviews mention a company or cite it as a source. This glossary explains the terms that come up along the way — from model knowledge through grounding and re-ranking to measurement with citation rate and share of AI search.

The groups follow the path a piece of content takes into an AI answer. Every term has its own page with a definition, how it works and what it means for your website.

The guide explains how it all fits together: [GEO optimization: what demonstrably works →](https://www.codaai.ai/en/knowledge/geo-optimization/)

Group 1 of 7

## How language models work

What an LLM does, where its knowledge comes from and why it turns content into numbers before comparing it.

- [GEO (Generative Engine Optimization) ](https://www.codaai.ai/en/knowledge/geo-glossary/geo/)also: Generative Engine Optimization, AI search optimisation, LLM optimisation, AEO, Answer engine optimisation, LLMO, GAIO

  GEO is the optimisation of content and brand so that AI systems such as ChatGPT or Google AI Overviews mention a company or cite it as a source.

- [LLM (Large Language Model) ](https://www.codaai.ai/en/knowledge/geo-glossary/llm/)also: Large Language Model, Language model, AI model

  An LLM is a language model that estimates the probability of the next token for a sequence of tokens. It generates text instead of looking it up in an index.

- [Token ](https://www.codaai.ai/en/knowledge/geo-glossary/token/)also: Tokens, Tokenisation, Tokenizer

  A token is the smallest unit a language model works with: a word, part of a word or a single character. All probabilities of an LLM refer to tokens.

- [Model knowledge ](https://www.codaai.ai/en/knowledge/geo-glossary/model-knowledge/)also: Parametric knowledge, Training knowledge

  Model knowledge is everything a language model saw during training, no more and no less. Answers from model knowledge are produced without a web search.

- [Common Crawl ](https://www.codaai.ai/en/knowledge/geo-glossary/common-crawl/)also: CCBot, Common Crawl dataset, Harmonic centrality, CC Rank

  Common Crawl is a non-profit, freely available archive of the internet with over 300 billion web pages from 19 years, and one of the main sources for training AI models.

- [Knowledge cut-off ](https://www.codaai.ai/en/knowledge/geo-glossary/knowledge-cutoff/)also: Training cut-off, Knowledge cutoff date, Data cut-off

  The knowledge cut-off is the point in time up to which training data has been fed into a language model. Anything after that date the model knows only via a web search.

- [Embedding ](https://www.codaai.ai/en/knowledge/geo-glossary/embedding/)also: Vector representation, Text embedding, Vector database

  An embedding is the translation of a text into a numeric vector that represents its meaning. Texts with similar meaning lie close to each other in vector space.

- [Cosine similarity ](https://www.codaai.ai/en/knowledge/geo-glossary/cosine-similarity/)also: Semantic similarity, Vector similarity, Cosine similarity score

  Cosine similarity measures how similar two vectors are: their dot product divided by the product of their lengths. AI systems use it to judge how well a text passage matches a search query.

- [Chunking ](https://www.codaai.ai/en/knowledge/geo-glossary/chunking/)also: Chunks, Text segmentation, Parsing & extraction, Passage indexing

  Chunking is the splitting of a text into small, self-contained sections (chunks) that an AI system stores, compares and uses in answers individually.

- [AI agents ](https://www.codaai.ai/en/knowledge/geo-glossary/ai-agents/)also: KI-Agenten, Browser agents, Agentic AI, AI agent, Autonomous agents

  AI agents are AI systems that complete tasks independently on a person's behalf: they plan steps, read and operate websites, fill in forms and compare offers.

- [AI hallucination ](https://www.codaai.ai/en/knowledge/geo-glossary/ai-hallucination/)also: Hallucination, LLM hallucination, Confabulation, AI misinformation

  An AI hallucination is a statement by an AI system that sounds plausible but is false or rests on no source. It arises because language models produce probable answers rather than verified ones.

- [Context window ](https://www.codaai.ai/en/knowledge/geo-glossary/context-window/)also: Context length, Context size, Token window

  The context window is the amount of text, measured in tokens, that a language model takes into account at once when answering. It includes instructions, the question, retrieved sources and the answer itself.

- [Knowledge graph ](https://www.codaai.ai/en/knowledge/geo-glossary/knowledge-graph/)also: Google Knowledge Graph, Knowledge base graph, Entity graph

  A knowledge graph is a knowledge base that stores real-world things as entities with a unique identifier and maps how they relate to one another. Search engines and AI systems use it to check facts.

- [Retrieval-augmented generation (RAG) ](https://www.codaai.ai/en/knowledge/geo-glossary/retrieval-augmented-generation/)also: RAG, Retrieval augmented generation, Retrieval-based generation

  Retrieval-augmented generation (RAG) is a method in which a language model retrieves matching texts from an external source before answering and bases its answer on those texts.

- [SynthID (AI watermark) ](https://www.codaai.ai/en/knowledge/geo-glossary/synthid/)also: AI watermark, Google SynthID, SynthID Text, SynthID Detector, KI-Wasserzeichen

  SynthID is Google DeepMind's watermarking technology for AI-generated content. It embeds a signal that humans cannot perceive into text, images, audio and video, which Google's verification tools can detect.

- [Vector database ](https://www.codaai.ai/en/knowledge/geo-glossary/vector-database/)also: Vector store, Vector index, Vector DB

  A vector database is a store for embeddings, the numerical vectors that represent the meaning of texts. For a given query, it finds the stored vectors that lie closest to it.

Group 2 of 7

## Web search and grounding

When an AI system looks things up live on the web — and what has to happen for your page to qualify as a source.

- [Web search (live retrieval) ](https://www.codaai.ai/en/knowledge/geo-glossary/web-search/)also: Live retrieval, Search grounding, Retrieval-Augmented Generation (RAG)

  Web search is the live retrieval by an AI system from the web, triggered when the model is not confident in its answer from model knowledge. Only here can current content have an effect.

- [Grounding ](https://www.codaai.ai/en/knowledge/geo-glossary/grounding/)also: Search grounding, Grounded response, Source anchoring

  Grounding is the process of anchoring an AI answer in external, current sources: the system finds matching web pages, extracts the relevant passages and builds the answer on them.

- [Query Fan-out ](https://www.codaai.ai/en/knowledge/geo-glossary/query-fan-out/)also: Fan-out queries, Query expansion, Fan-out

  Query fan-out is the splitting of a user question into several related search queries that an AI system sends to the search index in parallel to collect sources for its answer.

- [Document Relevance ](https://www.codaai.ai/en/knowledge/geo-glossary/document-relevance/)also: Page relevance, Document-level relevance

  Document relevance is the ‘classic SEO share’ of grounding: a page must rank among the top results for the query or its fan-out queries to be considered a citable source at all.

- [Grounding Budget ](https://www.codaai.ai/en/knowledge/geo-glossary/grounding-budget/)also: Grounding quota, Grounding chunks

  The grounding budget is the quota of pages and passages that an AI system, above all Gemini, draws on to ground an answer. Pages that rank well receive more of it.

- [Grounded Response Generation ](https://www.codaai.ai/en/knowledge/geo-glossary/grounded-response-generation/)also: Model context, Final answer, Answer synthesis

  Grounded response generation is the final step of an AI answer: the model synthesises model knowledge and model context — user question, personalisation, media and all grounding snippets — into a text with citations.

- [AI Overviews ](https://www.codaai.ai/en/knowledge/geo-glossary/ai-overviews/)also: AI Overview, Google AI Overviews, AIO, KI-Übersicht, Übersicht mit KI

  AI Overviews are AI-generated summaries in Google Search. They answer a question directly above or between the search results and link to the pages the answer is based on.

- [Google AI Mode ](https://www.codaai.ai/en/knowledge/geo-glossary/ai-mode/)also: AI Mode, KI-Modus, Google AI Mode search, AI Mode in Google Search

  Google AI Mode is Google's conversational AI search. It breaks a question into many searches using query fan-out, combines the results into an answer with links and lets users ask follow-up questions.

Group 3 of 7

## From ranking to citation

The four steps in which an AI system selects its sources: initial retrieval, re-ranking, grounding snippets, answer.

- [Initial Retrieval ](https://www.codaai.ai/en/knowledge/geo-glossary/initial-retrieval/)also: Candidate pool, Retrieval, First-stage retrieval

  Initial retrieval is the first selection step of an AI system: it collects the pages that rank best for the query and its fan-out queries into a candidate pool.

- [Re-Ranking ](https://www.codaai.ai/en/knowledge/geo-glossary/re-ranking/)also: Passage re-ranking, Relevance threshold, Cut-off

  Re-ranking is the second selection step of an AI system: individual text passages of the candidate pages are assessed, and only the most relevant ones pass the relevance threshold into the answer.

- [Grounding Snippets ](https://www.codaai.ai/en/knowledge/geo-glossary/grounding-snippets/)also: Grounding chunks, Snippets, Source excerpts

  Grounding snippets are the text passages that an AI system extracts from source pages and places as excerpts in the model's context in order to generate the answer from them.

- [Mention ](https://www.codaai.ai/en/knowledge/geo-glossary/mention/)also: Brand mention in AI, AI mention, Named mention

  A mention is the naming of a brand in an AI answer, regardless of whether a source is linked. It arises from model knowledge, from grounding or from both.

- [Citation ](https://www.codaai.ai/en/knowledge/geo-glossary/citation/)also: AI citation, Source link, Source reference, Retrieved vs. cited

  A citation is an AI answer's reference to a specific source (URL). It requires that the page was found, a passage was extracted and that passage was used for the answer.

- [Zero-Click ](https://www.codaai.ai/en/knowledge/geo-glossary/zero-click/)also: Zero-click satisfaction, Zero-click search, Answer without a click, Google Zero

  Zero-click describes a search that ends without a click on a website: the user receives a direct, summarised answer and is satisfied before visiting any page.

- [Hybrid retrieval (BM25 and embeddings) ](https://www.codaai.ai/en/knowledge/geo-glossary/hybrid-retrieval/)also: Hybrid search, BM25 plus embeddings, Lexical-semantic search

  Hybrid retrieval is the combination of lexical search such as BM25 and semantic search with embeddings. Both result lists are merged into one ranking that takes exact terms and meaning into account at the same time.

- [Semantic search ](https://www.codaai.ai/en/knowledge/geo-glossary/semantic-search/)also: Meaning-based search, Vector search, Dense retrieval

  Semantic search is a search method that finds results by their meaning rather than by matching words. The query and the texts are compared as embeddings, so sections with no words in common can still match.

Group 4 of 7

## Content factors

What makes a text readable, extractable and citable for AI systems.

- [Bottom Line Up Front (BLUF) ](https://www.codaai.ai/en/knowledge/geo-glossary/bottom-line-up-front/)also: BLUF, Answer first, Inverted pyramid

  Bottom Line Up Front is the principle of putting the core statement first: direct answer or summary first, reasoning afterwards. The key insights belong in the first 30% of the page.

- [Semantic chunking ](https://www.codaai.ai/en/knowledge/geo-glossary/semantic-chunking/)also: Chunk-optimised writing, Self-contained paragraphs, Passage optimisation

  Semantic chunking is a way of writing in which every paragraph is a self-contained answer to exactly one topic and every sentence remains understandable without context.

- [Entity echoing ](https://www.codaai.ai/en/knowledge/geo-glossary/entity-echoing/)also: Term echo, Entity reinforcement

  Entity echoing is the technique of repeating the term from a heading in the first sentence of the answer: if the H2 asks about site power, the answer begins with the words ‘site power’.

- [Entity ](https://www.codaai.ai/en/knowledge/geo-glossary/entity/)also: Entity density, Named entity, Knowledge graph node

  An entity is a uniquely identifiable ‘thing’ that an AI system recognises as such: a brand, a product, a person, a place, a technical term. Entity density means how many of them appear early in the text.

- [Information gain ](https://www.codaai.ai/en/knowledge/geo-glossary/information-gain/)also: Uniqueness, Original content, Novelty

  Information gain is the amount of new information a sentence or paragraph delivers beyond what is already in the model knowledge and in other sources. High gain makes content citable.

- [Topical authority ](https://www.codaai.ai/en/knowledge/geo-glossary/topical-authority/)also: Topic authority, Topic cluster, Content cluster

  Topical authority is the recognisable expertise of a domain in a topic area: does the entire content cluster signal that someone here has mastered the topic — instead of having a single page on it?

- [Query coverage ](https://www.codaai.ai/en/knowledge/geo-glossary/query-coverage/)also: Search query coverage, Topic coverage

  Query coverage is the coverage of a topic area: does a domain rank not only for the main query but also for the related fan-out queries an AI system generates for a question?

- [E-E-A-T ](https://www.codaai.ai/en/knowledge/geo-glossary/e-e-a-t/)also: Experience, Expertise, Authoritativeness, Trustworthiness, E-A-T, Authorship

  E-E-A-T stands for Experience, Expertise, Authoritativeness and Trustworthiness — the signals by which search engines and AI systems recognise whether content is first-hand, competent, recognised and trustworthy.

- [Freshness ](https://www.codaai.ai/en/knowledge/geo-glossary/freshness/)also: Content freshness, Currency, lastModified

  Freshness is the recognisable currency of a piece of content. AI systems cite older content significantly less often — ‘as of 2023’ loses to current content, and the date has to be technically visible.

- [AI-friendly content formats ](https://www.codaai.ai/en/knowledge/geo-glossary/ai-friendly-content-formats/)also: LLM-readable content, AI-readable content, Structured content

  AI-friendly content formats are structures that AI systems extract easily: lists, tables, comparisons as tables instead of prose, a clear heading hierarchy, Q\&A headings and a summary before the footer.

- [llms.txt ](https://www.codaai.ai/en/knowledge/geo-glossary/llms-txt/)also: llms-full.txt, LLMs.txt standard

  llms.txt is a proposed text file in the root directory of a website that offers language models a curated overview of the most important content. A measurable effect on AI citations has not been demonstrated so far.

- [LLM readability ](https://www.codaai.ai/en/knowledge/geo-glossary/llm-readability/)also: LLM-Lesbarkeit, LLM Readability Optimization, AI readability, Readability for LLMs

  LLM readability is a concept coined in 2024 by Olaf Kopp (Aufgesang): content should be written and structured so that language models can process it easily and cite it as a source.

Group 5 of 7

## Technology

The entry ticket: what a crawler has to find so that content is captured at all.

- [LLM crawlers ](https://www.codaai.ai/en/knowledge/geo-glossary/llm-crawlers/)also: AI user agents, AI bots, GPTBot, Google-Extended, OAI-SearchBot

  LLM crawlers are the bots of the AI providers — GPTBot, ClaudeBot, ChatGPT-User, PerplexityBot, CCBot and others — that visit web pages for training or for the live retrieval of an answer. They do not render JavaScript.

- [TTFB (Time to First Byte) ](https://www.codaai.ai/en/knowledge/geo-glossary/ttfb/)also: Time to First Byte, Server response time, Server latency

  TTFB is the time from the request to the first byte of the server response. For LLM crawlers the guideline is under 500 to 800 milliseconds — otherwise the fetch is aborted, with no retry.

- [URL Discovery ](https://www.codaai.ai/en/knowledge/geo-glossary/url-discovery/)also: URL findability, Crawlability, Internal linking

  URL Discovery is the question of whether crawlers can find a website's relevant content at all: via HTML links, a current sitemap and without click or login walls in front of important content.

- [Crawl Budget ](https://www.codaai.ai/en/knowledge/geo-glossary/crawl-budget/)also: Crawl management, Crawl control, Crawl allocation

  Crawl budget is the number of fetches a crawler devotes to a website in a given period. Crawl management makes sure this budget goes to the pages that really count.

- [Index Management ](https://www.codaai.ai/en/knowledge/geo-glossary/index-management/)also: Indexing, Indexability, Noindex and canonical

  Index management is the control over which URLs of a website are indexable: noindex only for content that should not appear in AI answers, canonical tags only for unavoidable duplicate content.

- [Accessibility tree ](https://www.codaai.ai/en/knowledge/geo-glossary/accessibility-tree/)also: A11y tree, Accessibility-Baum, Barrierefreiheitsbaum, Browser accessibility tree

  The accessibility tree is a simplified version of the DOM generated by the browser, holding the roles, names and states of page elements. Screen readers use it — and so, increasingly, do AI agents.

- [Agentic commerce ](https://www.codaai.ai/en/knowledge/geo-glossary/agentic-commerce/)also: Agentic shopping, Agent-led commerce, Agentischer Handel, Agentic Commerce Optimization, ACO

  Agentic commerce is commerce in which AI agents research products, compare offers and complete the purchase on a person's behalf — based on machine-readable product data.

- [IndexNow ](https://www.codaai.ai/en/knowledge/geo-glossary/indexnow/)also: Index Now, IndexNow protocol, IndexNow API, IndexNow ping

  IndexNow is an open protocol that lets a website notify search engines instantly of new, changed or deleted URLs. One submission reaches all participating search engines, including Bing — Google is not among them.

- [Structured data (Schema.org) ](https://www.codaai.ai/en/knowledge/geo-glossary/structured-data/)also: Schema.org, Schema markup, JSON-LD, Structured markup

  Structured data is machine-readable information in a web page's source code that uses the Schema.org vocabulary to describe what is on the page — such as a company, a product or an article.

- [WebMCP ](https://www.codaai.ai/en/knowledge/geo-glossary/webmcp/)also: Web MCP, WebMCP API, document.modelContext, Agent tools for websites

  WebMCP is a proposed web standard that lets websites provide AI agents with structured tools — declaratively through annotated HTML forms or imperatively through JavaScript.

Group 6 of 7

## Off-page and brand

Why the AI judges your company through third-party sites as well — and which ones count.

- [Brand Mentions ](https://www.codaai.ai/en/knowledge/geo-glossary/brand-mentions/)also: Unlinked mentions, Third-party mentions, Brands matter more than websites

  Brand mentions are references to a brand on third-party sites — in forums, communities, trade media, comparisons. AI systems weight them even without a link, because the brand image emerges from the sum of all sources.

- [Consistent brand description ](https://www.codaai.ai/en/knowledge/geo-glossary/consistent-brand-description/)also: Brand consistency, Uniform brand image, Entity consistency

  Consistent brand description means a brand is described with the same wording on every platform — on its own website and by third parties. Only then does an AI system recognise it as one entity.

- [Grounding page ](https://www.codaai.ai/en/knowledge/geo-glossary/grounding-page/)also: Grounding pages, Facts page, Fact sheet, Company facts, Brand facts page, Single source of truth

  A grounding page is a page on a company’s own website that provides its verified key facts in one place, dated and citable — as a reliable source for AI systems.

- [Digital PR & Content Distribution ](https://www.codaai.ai/en/knowledge/geo-glossary/digital-pr/)also: Digital PR, Earned media, Content distribution

  Digital PR & Content Distribution is the work of getting a brand written about in recognised publications: trade media, industry blogs, guest articles, expert quotes and placements in comparison articles.

- [Listicles ](https://www.codaai.ai/en/knowledge/geo-glossary/listicles/)also: Best-of lists, Comparison articles, Third-party rankings

  Listicles are ‘best of’ and comparison articles on third-party sites (‘The 10 best providers for …’). AI systems cite them especially often for provider and comparison questions — presence there is a direct lever for mentions.

- [Community presence (Reddit & forums) ](https://www.codaai.ai/en/knowledge/geo-glossary/community-presence/)also: Reddit presence, Forum presence, Community mentions

  Community presence means authentic recommendations of a brand in relevant threads on Reddit and in specialist forums. AI systems cite such sources often — self-promotion does not help, nuanced, honest mentions do.

- [Review platforms ](https://www.codaai.ai/en/knowledge/geo-glossary/review-platforms/)also: Rating platforms, Review sites, Customer reviews

  Review platforms such as Trustpilot, Capterra, Kununu or Stiftung Warentest are rating sources that AI systems cite for trust and reputation questions. Presence there raises the chance of being cited significantly.

- [YouTube presence ](https://www.codaai.ai/en/knowledge/geo-glossary/youtube-presence/)also: Video presence, YouTube for AI visibility

  YouTube presence means a brand's own videos on YouTube that AI systems use as a source. YouTube links are among the top correlation factors for visibility in AI Overviews and ChatGPT — even with low view counts.

- [Domain Authority ](https://www.codaai.ai/en/knowledge/geo-glossary/domain-authority/)also: Domain strength, Backlink profile, Site authority

  Domain Authority in the GEO context describes whether a domain counts as a leading voice in its field, based on backlinks (including nofollow), presence in trade publications and entries in knowledge sources such as Wikipedia.

- [Corroboration ](https://www.codaai.ai/en/knowledge/geo-glossary/corroboration/)also: Third-party corroboration, Third-party confirmation, Consensus, Source agreement

  Corroboration is the confirmation of a statement by several independent sources. AI systems treat matching statements about a brand as a trust signal and are then more likely to repeat them in their answers.

- [Entity home ](https://www.codaai.ai/en/knowledge/geo-glossary/entity-home/)also: Entity home page, Entity canonical, Point of reconciliation

  The entity home is the one page that authoritatively describes a brand, company or person. Algorithms reconcile what they find elsewhere about that entity against it — usually it is the homepage or the about page.

Group 7 of 7

## Measurement and tracking

How AI visibility can be measured, why a position is useless here and which metrics carry the weight instead.

- [LLM Visibility Tracking ](https://www.codaai.ai/en/knowledge/geo-glossary/llm-visibility-tracking/)also: AI Visibility Tracking, Prompt Tracking, AI visibility measurement

  LLM Visibility Tracking is the measurement of AI visibility: prompts are sent to AI systems and the answers are analysed for mentions and citations of the brand, as a probability across many runs rather than a position.

- [Prompt set ](https://www.codaai.ai/en/knowledge/geo-glossary/prompt-set/)also: Proxy prompts, Prompt list, Question set, Unbranded prompts

  A prompt set is a fixed set of proxy prompts that represents the topics and customer questions of a brand. It is the basis of every measurement of AI visibility, comparable to the keyword set in SEO.

- [Baseline measurement ](https://www.codaai.ai/en/knowledge/geo-glossary/baseline-measurement/)also: Baseline, Initial measurement, Zero measurement

  The baseline measurement is the first complete survey of Mention Rate, Citation Rate, Sentiment and Share of AI Search across a prompt set, before any measures, as the reference for everything measured afterwards.

- [Mention Rate ](https://www.codaai.ai/en/knowledge/geo-glossary/mention-rate/)also: Brand Mention Rate, Mention frequency, Brand mention share

  The Mention Rate is the share of AI answers in a prompt set in which a brand is mentioned by name, measured across many runs, per system, as a probability rather than a position.

- [Sentiment ](https://www.codaai.ai/en/knowledge/geo-glossary/sentiment/)also: Sentiment analysis, Brand Sentiment, Tonality

  Sentiment describes how a brand is rated in an AI answer: positive, neutral or critical. A mention is only valuable if the sentiment is right. Mentioned is not recommended.

- [Citation Rate ](https://www.codaai.ai/en/knowledge/geo-glossary/citation-rate/)also: AI Citation Rate, Source rate, Citation frequency

  The Citation Rate is the share of AI answers in a prompt set in which one of your own pages is cited as a source. It measures whether content is found, extracted and used for the answer.

- [AI Overview Citation Rate ](https://www.codaai.ai/en/knowledge/geo-glossary/ai-overview-citation-rate/)also: AIO Citation Rate, AI Overviews visibility, AI Overview source rate

  The AI Overview Citation Rate measures how often a page appears as a source in Google AI Overviews, observable via the ‘Generative AI’ report in Search Console.

- [Share of AI Search ](https://www.codaai.ai/en/knowledge/geo-glossary/share-of-ai-search/)also: Share of Voice (SOV), AI Share of Voice, Share of AI answers

  Share of AI Search is the share a brand holds of the AI answers to a fixed prompt set, compared with competitors and over time. In AI search, it replaces click numbers as the leading metric.

- [Source analysis ](https://www.codaai.ai/en/knowledge/geo-glossary/source-analysis/)also: Citation source analysis, Source audit, Cited domains

  Source analysis evaluates which third-party sites AI systems cite for the prompts in a set. It shows where a brand needs to be present, because that is where the evidence for the answers comes from.

- [Log files (LLM crawler requests) ](https://www.codaai.ai/en/knowledge/geo-glossary/log-files/)also: Server logs, LLM crawler requests, Log file analysis

  Log files show the actual requests from LLM user agents to the server. They prove that a page was retrieved, not that it ended up in an AI answer. A server log does not yet mean visibility.

- [Citation Share ](https://www.codaai.ai/en/knowledge/geo-glossary/citation-share/)also: Bing Citation Share, Citation share metric, Share of citations, Zitieranteil

  Citation Share is a metric in the AI Performance report of Bing Webmaster Tools. It shows what proportion of all citations for a grounding query your website receives in Copilot and Bing's AI answers.
