IIRC it wasn't that impressive in the end as instead of recognizing the places the AI apparently learnt to recognize subtle differences in street view cameras used in different locations? I might be wrong / thinking of the wrong model l and I'm on mobile without my browsing history so hard to check, but I think it was putting a lot of weight on some pixels that are noisy

Top geoguessr players use this technique as well. IIRC rainbolt mentioned that there is a section of a country where the street view camera has a small blemish from a raindrop on the camera so you can instantly tell where you are if you notice that.

From my understanding many of the best players immediately look down to tell what "generation streetview car" they're using, and seem to know what continents/times they're from.
