Supported AI Models & Sources

Learn which AI engines are supported in AI Visibility, how different models behave, what web grounding vs training data means, and why tracking multiple AI engines is critical for accurate visibility measurement.

Updated over 2 weeks ago

What it is

AI Visibility supports tracking across multiple AI engines, including:

  • Google AI Overviews

  • ChatGPT

  • Gemini

  • AI Mode

  • Perplexity

  • Claude

  • Copilot

  • Other supported large language models (LLMs)

Each engine is tested independently. When you select engines for a search term, the system sends the exact prompt to each model and analyzes the generated response separately.

This means visibility data is engine-specific, not blended across platforms.


Why it matters

AI search is not one unified ranking system.

Each AI engine:

  • Uses a different model architecture

  • Has different training data

  • Applies different web grounding logic

  • Varies in how it cites sources

  • Updates independently

A brand may:

  • Rank prominently in one engine

  • Be mentioned lower in another

  • Not appear at all in a third

Tracking only one engine creates blind spots.

By monitoring multiple models, you:

  • Reduce visibility risk

  • Identify engine-specific strengths and weaknesses

  • Benchmark competitors more accurately

  • Detect model-driven shifts early

AI visibility is ecosystem-based. There is no single β€œAI ranking.”


How AI models differ

While AI engines may answer similar prompts, they behave differently in practice.

Differences can include:

  • How brands are ordered in responses

  • How often citations are shown

  • Whether external links are included

  • How commercial vs informational queries are handled

  • How frequently models update

Some engines produce structured, citation-heavy responses. Others produce conversational summaries with fewer references.

These differences affect:

  • Detection rate

  • Position consistency

  • Citation volume

  • Perceived authority

Understanding these distinctions helps you interpret visibility correctly.


Sources explained: web grounding vs training data

AI engines generate answers using a combination of internal model knowledge and, in some cases, live web sources.

Web grounding (GR)

When web grounding is used:

  • The AI retrieves live or near-real-time web content

  • Citations or links may appear in the response

  • Recently published content can influence visibility

This means traditional SEO authority and content freshness can directly impact AI visibility.


Training data (TR)

When relying on training data:

  • The AI uses pre-trained knowledge

  • No live links are required

  • Mentions may appear without citations

In these cases, brand authority, recognition, and historical web presence influence visibility, even if no direct link is shown.


Why this distinction matters

You may see:

  • Mentions without citations

  • Citations without top position

  • Visibility shifts without ranking changes in Google

This is normal.

AI Visibility tracks both contextual mentions and citations to give a complete picture.


Model updates & visibility shifts

AI engines update their models regularly.

These updates can:

  • Change brand ordering

  • Alter citation behaviour

  • Modify how commercial queries are answered

  • Shift detection patterns

Because updates are independent per engine, you may see changes in one model but not others.

Tracking multiple engines helps you:

  • Identify model-specific volatility

  • Separate systemic shifts from isolated fluctuations

  • Maintain stable performance benchmarking


How to choose which engines to track

Recommended approach:

  • Track at least 2-3 major AI engines

  • Include both citation-heavy and conversational models

  • Prioritize engines relevant to your audience

For high-priority commercial queries, use higher update frequency on primary engines and lower frequency on secondary ones.


What to expect

  • Visibility will vary across engines

  • Citation behavior differs by model

  • Positioning logic is not identical

  • Trends matter more than single runs

AI Visibility is designed to help you understand how your brand performs across the evolving AI search ecosystem, not just one interface.


Best practices

  • Compare engine-specific performance regularly

  • Use engine filters in the dashboard to isolate trends

  • Monitor sudden shifts following major AI model releases

  • Treat cross-engine visibility as a strategic advantage
