I used it to place some old vacation photos.

These were taken without EXIF for GPS (because the cameras did not have GPS), and it was still very good. With anything turisty it got them immediately, and with my photo of a house on the Muese river it got it nearly perfect. When I added a few more photos I was able to nail it down to a couple hundred meters.

I did it all with 4o (the old model), the only issue is that if it starts to search the internet it will then lie to you that its not able to read pictures.
