Apple announced it has rebuilt Siri using a custom Google Gemini AI model during its annual developers conference on June 8, 2026 [1].
The overhaul represents a pivotal shift in Apple's approach to generative AI, integrating external technology to remain competitive while signaling a leadership transition at the highest level of the company.
CEO Tim Cook delivered his final WWDC keynote address before stepping down from his role [1]. The event, held at Apple Park in Cupertino, California [5], featured presentations from Cook and senior executive John Ternus [1].
The company revealed that AI upgrades will be integrated across several platforms, including iOS 27 [4], iPadOS 27 [5], and macOS GoldenGate [6]. The centerpiece of these updates is the new Siri, which now operates on the Gemini custom Google AI model [7] to enhance its capabilities.
Beyond software updates, Apple expanded its health-monitoring ecosystem. The Apple Watch now includes a feature designed to detect early signs of perimenopause [8]. This addition continues the company's trend of moving the Apple Watch further into the clinical health space.
The keynote began at 10 a.m. PDT [2], with updates rolling out to the broader ecosystem of Apple devices. This strategic pivot to Google's AI architecture marks a departure from Apple's traditional reliance on in-house development for its primary voice assistant.
Cook's departure marks the end of an era for the company, as he transitions away from the leadership position he has held since 2011. The integration of Gemini suggests a new era of partnership between the two tech giants to bridge the gap in generative AI functionality.
“Apple announced it has rebuilt Siri using a custom Google Gemini AI model.”
The integration of Google's Gemini model into Siri indicates that Apple has prioritized rapid AI deployment over total proprietary control to keep pace with the generative AI race. Simultaneously, the departure of Tim Cook creates a leadership vacuum that may lead to further shifts in corporate strategy, particularly as Apple continues to pivot from a hardware-first company toward a services and health-tech powerhouse.
