How we ran the research
For the October 2026 pages, each question ran once in the Glasa product through 5 AI engines, with the market set to the country. Firm mentions were extracted from the answer texts. One run on one day: AI answers change between runs, accounts and locations, so treat the counts as a snapshot, not a ranking of quality. Each research page lists the exact questions and method.
