Measurement surfaces
An engine name is not a complete measurement definition. S6S records the provider surface, model/configuration, question, time, and outcome so a result is not mistaken for every consumer experience from that company.
Internal-alpha boundary
Provider-data permissions and retention behavior are being reviewed before an external monitored pilot. A surface may be disabled rather than measured when its permitted data path is unresolved.
ChatGPT
- Measured surface
- An OpenAI API/search response surface configured by S6S.
- Not implied
- The signed-in ChatGPT consumer application, its personalisation, or every product experience carrying the ChatGPT name.
Gemini
- Measured surface
- A Gemini API response surface with its configured grounding behavior, when that data path is permitted and enabled.
- Not implied
- The Gemini consumer application, Google AI Overviews, or Google AI Mode.
Perplexity
- Measured surface
- A Perplexity Sonar API/search response and its returned citations.
- Not implied
- Every state, personalisation, or interface behavior of the Perplexity consumer application.
Comparison rules
- Use the same defined buyer question and sampling contract when comparing funded surfaces.
- Keep responses, citations, timestamps, and failure states attributable to their own surface.
- Never convert unavailable, failed, or never-run measurements into zero visibility.
- Do not present an API/search result as a direct observation of a consumer application.
- Treat later responses as new observations; do not guarantee that an intervention caused a change.
Provider products and terms change. The run record, not this overview page, is the authority for the exact model/configuration used by a specific observation.
