In a general rule you can record. But sending it to Meta AI would be a AVG (GDPR) violation in the Netherlands if no consent is given as you share it with a third party. There is also the difference of recording a public place with people in the background and clearly recording someone: The first is fine, the second is not (without consent). You also cannot disable the recording light, doing so would put you up for libel en decency lawsuits (and libel and public decency can be criminal, not just misdemeanors).

So if you take a video of specific people looking at flowers at the Keukenhof you would have to ask them for permission if you are recording them primarily and publish it but recording for yourself is fine as it is a clearly public space. If you take a picture of all the flower and catch some people in it in the background you are fine. If you do it in a place where people do not expect it they can ask you to remove the video and they have to (e.g. in a restaurant when you are eating as it is not expected to be recorded there).

There are some exceptions for journalism, law enforcement and public good. I doubt strongly any Meta (AI) post would classify for that.

There is also the small caveat that if you can avoid recording innocent bystanders you must. E.g. putting up a doorbell camera and pointing it to the street instead of your door is bad as it's easily avoidable by putting it top down.
