Musk Says He’s Open to Letting xAI’s Grok 4.1 Power Apple’s Siri

The openness lands during Apple experiments that let iPhone owners in Japan launch third‑party assistants from the side button.

Overview

  • Elon Musk replied “I’m down” to an X user’s call for Apple to replace Siri’s intelligence with xAI’s Grok 4.1, though no collaboration has been announced.
  • xAI launched Grok 4.1, described as its most advanced model with stronger reasoning, creative output and reduced hallucinations, available on X and at grok.com for free.
  • Bloomberg reporting says Apple is considering using a tailored 1.2‑trillion‑parameter Google Gemini model for next‑generation Siri under a deal estimated at about $1 billion per year, which remains unfinalized.
  • Developer beta code for iOS in Japan indicates users could assign the side or Action button to invoke a third‑party assistant via App Intents, a shift from Siri‑only system access.
  • A U.S. judge allowed antitrust claims from Musk’s companies X and xAI against Apple to proceed, including allegations of collusion with OpenAI and App Store favoritism toward ChatGPT.
