Why wait? Why not switch now?
In other words, meta is harvesting your WhatsApp data, and gives you a (potentially inaccurate) summary in exchange for feeding their LLMs.
I think another blog mentioned that you have to enable it yourself first and then press the AI button to send it to be processing. If that's the case then it's not that bad
Until they change their ToS (without telling you) and enable it by default (and hide the controls that let you decline).
It will be big news when that happens
Seems like a Trojan horse to get users to grant access to their encrypted chats?
I'm interested in how they've allegedly achieved this working without anyone but you having access to the unencrypted messages.
Don't get me wrong, I want none of this shit in a messaging app, but I'm at least interested in how that is supposed to work.
It could run entirely on-device.
According to Meta it runs on their private servers
From what I gather the texts are encrypted and sent to their LLMs that process it with some mechanism to verify the code being run in the cloud to process the texts is one that the WhatsApp app agreed to.
But they could just as well start siphoning the data after changing that code. Everyone will be able to see the cloud code changed if/when tbat happens but I don't think there's a way to differentiate that from a regular update.
Don't think theyve opensourced any of this
Fascinating. Just based on your comment and nothing else, sounds like it could be something like a CPU Enclave like Intel SGX. Basically a remote client can validate that an application runs in a secure part of a remote cloud computer. The stated goal of SGX is that you only have to trust Intel and if you trust Intel and say run program X in the enclave, then only that part of the CPU can access the data, not the applications running in the non-secure enclave.
Now that brushes over some things like you still need to trust the client and IIRC in a WhatsApp situation, you don't really know what enclave does, but the communications between the enclave and the host OS are heavily restricted. LLMs also require lots of CPU and are usually run on GPUs, so not sure how that works yet.
They use GPU based enclaves. They have a white paper available. I just seemed it but they mention AMD and NVIDIA enclaves.
They might publish components of it enough to verify that the processing code is not emitting any data but as others said - it could've been done locally on the phone
it’s surprising this feature is opt-in. either way, fuck meta.
I think they're still testing it and testing the waters with this. Probably opt-out later on
Bros got that 9:100 phone
And just like that, end-to-end encryption vanishes again.
Did anyone ask for this, it's a messaging app
probably the owner of the pictured ~~sword~~ phone
LOL
Hey Meta AI, can you summarize that for me?
ShaggySnacks had a good laugh
Would be a good feature if it works and is private.
I'm in multiple group chats and often open WhatsApp to see 800 unread messages in a single chat. I don't want to read through all of that, but I do want to know a high level overview, so I can see if it's something I actually want to scroll back to and have a proper read.
However, I've seen multiple AI summaries missing out important stuff, so that's almost certainly going to be an issue here too.
I also want it to be completely private. They say it is, but who knows? The fact it's not on-device is a bit of a red flag to me.
Yes!!! Keep enshittifying! Yes! nods menacingly
And with that, room for misinterpretation.
This sounds like it might be useful for some people who get lots of messages, like businesses at least, but I just don’t trust Meta.
Also, I wouldn't trust a hallucinating LLM with my business messages honestly.
