APPLE is giving more people the chance to test a software update that will implant artificial intelligence (AI) into its virtual assistant Siri and automate a variety of tedious tasks on the latest iPhone coming out on Friday.

The free update was made available Thursday to an audience that has signed up to test Apple's software before it's released to all iPhone owners next month. As of Thursday, only two premium iPhones that came out last year contain the souped-up processor required to power the AI features included in the update, but that will change Friday when four new iPhone 16 models reach store shelves.
