How much size would it take to store a model of every known location in the world and common things?

For ex: I sent a friend a photo of my puppy in the bathtub and her Airpods (via iphone) announced "(name) sent you a photo of a dog in a bathtub". She thought it was really cool and so do I personally. That's a useful feature. IDK how much that requires going off-device though.

I’m really curious how this feature is considered useful. It’s cool, but can’t you just open the photo to view it?

It is a notification summary.

There is a large number of people out there who receive hundreds of notifications (willingly but mostly unwillingly) daily from apps they have installed (not just messengers), and nearly all of them can't cope with the flood of the notifications. Most give up on tending to the notifications altogether, but some resort to the notification summaries which alleviate the cognitive overload («oh, it is a picture of a dog that I will check out when I get a chance to, and not a pic of significant other who got themselves into a car accident»).

The solution is, of course, to not allow all random apps to spam the user with the notifications, but that is not how laypeople use their phones.

Even the more legit apps (e.g. IG) dump complete garbage upon unsuspecting users throughout the day («we thought you would love this piece of trash because somebody paid us»).

Hundreds of notifications daily is not unwillingly, nor is it healthy.

You can disable IG trash notifications, for example.

The power of defaults is strong.

Most people using the device will never go into the notification settings, if an app on install tells you they need notifications to tell you about your driver arriving…and then sends you marketing notifications on the same channel most people will just accept that.

My IG notifications are disabled in perpetuity precisely for that reason, even if it has come at a cost of not receiving IM arrival notifications from a couple of friends who message me exclusively via IG (another enigma – why, as both have my contact details on proper messaging platforms).

Frankly, hundreds of daily notifications is the reality we can't change, and the question is: why do people choose to succumb to the misery of it rather than availing themselves of the proper implements so readily at their disposal?

My armchair explanation is that people can’t cope with being bored. All those notifications are little bits of dopamine hits each time they arrive. It’s not even FOMO, just waiting for something that may be interesting.

With an assault of notifications while you are busy, being able to determine without lifting your phone whether the alert is something mundane versus what you've been waiting for, is useful. If I'm working outside, removing gloves to check the phone each time it vibrates becomes endlessly disruptive, but I want the phone with me in case family calls, someone's delivering something, there's an urgent work issue, etc.

I’m not an expert, but I would say extremely small.

For comparison Hunyuan video encodes a shit-ton of videos and rudimentary real world physics understanding, at very high quality in only 13B parameters. LLAMA 3.3 encodes a good chunk of all the knowledge available to humanity in only 70B parameters. And this is only considering open source models, the closed source one may be even more efficient.

Maybe we have different understandings of what extremely small is (including that emphasis) but an LLM is not that by definition (the first L). I'm no expert either but the smaller value mentioned is 13e9. If these things are 8-bit integers, that's 13 GB data (more for a normal integer or a float). That's a significant percentage of long term storage on a phone (especially Apple models) let alone that it would fit in RAM on even most desktops which is afaik required for useful speeds. Taking this as upper bound and saying it must be extremely small to encode only landmarks, idk. I'd be impressed if it's down to a few dozen megabytes, but with potentially hundreds of such mildly useful neural nets, it adds up and isn't so small that you'd include it as a no-brainer either
