Dentists in London: which clinics ChatGPT and Gemini name
Gemini sends people to Bow Lane Dental Group far more often than ChatGPT does. The clinic appeared in 45 of 90 answers from Gemini, but in just 5 of 90 answers from ChatGPT. ChatGPT leaned elsewhere, naming Marylebone Smile Clinic in 24 of 90 answers, so the dentist you hear about depends a good deal on which assistant you open.
Searching the web brings in a different name. Wimpole Street Dental Clinic never came up when the models answered from memory, but once they looked online it was named in 25 of 72 answers. The list goes quiet for an urgent toothache. Asked simply where to get help, the answers named none of these clinics at all. Asked to weigh the options, they named Smile Cliniq in 1 of 12 answers and no other clinic from the list.

How London was measured
Each of the 18 questions went to ChatGPT and to Gemini, in 3 separate runs; 12 of them were asked twice, with the model's web search off and on. A question that itself named a clinic is left out, since its answer would name that clinic by force. The clinics we tracked are the ones we chose to measure in London and the clinics they compete with for the same patients.
Ansmeter Benchmark v2.0, methodology 2026.10, prompt library 2026.10-service-voice. The method and its limits: Methodology. The table as a file: data.csv.
We ran this measurement on our own initiative; no clinic asked for it or paid for it. If a clinic's name or website is wrong here, write to us and we will correct it.
