I ran a few of these geo guess queries between OpenAI O3 and Gemini Pro 2.5 and O3 does much better on average.

It does spend an order of magnitude longer time on inference by searching through websites and analyzing the image but it often produces an impressive output. To me it also feels Gemini down samples the image as it tends to have a harder time reading small text vs O3.

That said O3 did tend to confidently say false things
