Apple is making an executive change to try and improve its AI efforts and Siri. Kim Vorrath, who recently helped get the Vision Pro software out the door and has been at Apple for 36 years, has been brought over to Apples artificial intelligence and machine learning division and will serve as a top deputy to AI boss John Giannandrea, Bloomberg reports.The company made a big splash about its AI / Apple Intelligence efforts at WWDC last year, but they havent had the same impact as things like OpenAIs ChatGPT or Googles Gemini. Apple has also been slowly rolling out what it announced, and a big Siri upgrade that lets it understand whats happening on your screen and take action may not arrive until iOS 18.4. And the companys AI-powered news notification summaries will be put on pause with iOS 18.3 after criticism that the summaries were incorrect.By bringing on Vorrath, whose resume at Apple includes work on the original iPhone software group, over to the AI team, it appears Apple wants to bring more rigor to Apples AI development. It also indicates that Apple may see AI as a bigger deal for its future than the Vision Pro.Bloomberg also reports that the artificial intelligence group is focused on revamping the underlying infrastructure of Siri and improving the companys in-house AI models this year, per a memo from Giannandrea.
