Respectfully, I do have a much better idea than most people about what is being deployed and used, as I built some of them.

I am not saying it is bulletproof. I am saying it will reliably pull 10 photos of the same person out of 100,000,000 total photos, for any given person, based off a single new photo it has never seen before. That’s the kind of scale and accuracy we’re talking about here, it’s not parlor games. And that 100M was small fries compared to bigger players - who I am sure were into the billions, with even better precision than we had.

I still don’t understand the multiple objections I see relating to “top of the line equipment” or advanced expensive software. The mental model you should have is something like Copilot or GPT3.5. The landlord is just buying access to a nice UI that makes API calls.
