> Apple --> OpenAI can make a device that runs ChatGPT as the OS instead of relying on iOS.

Or, instead of spending billions training models that are nearly all the same, they instead take advantage of all the datacenter full of GPUs, and AI companies frantically trying to make a profit, many most likely crashing and burning in the process, to pay relative pennies to use the top, nearly commoditized, model of the month?

Then, maybe someday, starting late and taking advantage of the latest research/training methods that shave off years of training time, save billions on a foundation model of their own?

I don't think it makes sense for Apple to be an AI company. It makes sense for them to use AI, but I don't see why everyone needs to have their own model, right now, during all the churn. It's nearly already commodity. In house doesn't make sense to me.
