Is Apple investing in AI as much as Google, Meta, Microsoft, and xAI? If not they are not "all in".

they are investing differently. Apple has a much more captive audience than the others, and as such is focused on AI services that can be run on device. as such, they aren't doing the blessing edge foundation modern research, but instead putting a ton of money into productionizing smaller models that can be run without giant cloud compute.

They don’t disclose it, but I’d imagine so. They also admit to being a couple of years late, so they’re accelerating (as per their last earnings call)
