I wish they did but they don't. They have been for decade so stingy on RAM for iPhone and iPad. There are at current point that only small percent of their userbase have iPhone or iPad with 8GB RAM that somehow can run any AI models even open source and be of any use. Not mentioning they don't compare to big Models.
They don't even provide option to sell iPhone with bigger RAM. iPad can have max 16GB RAM. Those mainstream macbook air also can have max 32 GB RAM.
And for the current price of cheap online AI where e.g. perplexity provides so many promo for PRO version for like less $10 per year and all ai providers give good free models with enough rate limit for many users I don't see apple hardware like particularly bought because of AI compute-chips - at least not non-pro users.
If the loose AI though and because of that won't have good AI integrations they will loose also eventually in hardware. e.g. Polish language in Siri still not supported so my mum cannot use it. OSS Whisper v3 turbo was available ages ago but apple still support only few languages. 3rd party keyboard cannot integrate so well with audio input and all sux in this case because platform limitation.
