Dentists in Oslo: which clinics ChatGPT and Gemini name
Memory does little for Tannlegene på Sinsen. When ChatGPT and Gemini answered without searching the web, the name turned up in 1 of 72 answers; once they could search, it jumped to 29 of 48. For a demanding implant case the picture shifts again: Christiania Tannlegesenter came up in 2 of 8 of those answers, while Oslo Tannlegesenter did not come up in them at all.
Oslo Tannlegesenter was named in 74 of 120 answers. Two names from outside the list came up about as often: Colosseum Tannlege, in 79 of 120, and Oris Dental, in 70 of 120.

How Oslo was measured
Each of the 18 questions went to ChatGPT and to Gemini, in 2 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 Oslo 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.
