Again, political violence has no place in this country.
I probably don’t agree with Charlie Kirk on a damn thing, but that doesn’t matter - he’s a husband and a father.
This is despicable and can’t become our new normal.

🚀 DinoV3 just became the new go-to backbone for geoloc!
It outperforms CLIP-like models (SigLip2, finetuned StreetCLIP)… and that’s shocking 🤯
Why? CLIP models have an innate advantage — they literally learn place names + images. DinoV3 doesn’t.
