There was a programme the other day about this on BBC Radio 4. Unless they’ve resolved the problem already, it will refuse to describe any scene with faces in it, for privacy reasons. Which obviously rules out a lot of useful use-cases. You’re in a cafe wondering what’s going on, Be My AI can’t help if there’s a face. I think it was related to some EU legislation which Be My Eyes are now at least trying to change for this use-case. I wish them the best of luck.
