The famous O3 "GeoGuessr" prompt did not work

The viral o3 GeoGuessr geolocation capability, where the model identified photo locations with surprising accuracy, no longer reliably reproduces. This suggests OpenAI may have patched or constrained the behavior post-release, raising a practical concern for evaluators: model capabilities can degrade silently between versions, making point-in-time benchmarks unreliable for deployment decisions.
