Cupertino, California – Apple will open its Worldwide Developers Conference on Monday, June 8, 2026, with Tim Cook delivering his final keynote address as chief executive officer, drawing heightened attention to both the event and the company’s longer-term strategy. The conference will center on a comprehensive overhaul of Siri, which will run on a custom 1.2-trillion-parameter Gemini model licensed from Google, marking a decisive break from Apple’s prior reliance on OpenAI’s ChatGPT for conversational intelligence. Gemini will serve as the default assistant across Apple devices, with the upgrade positioned as a core part of Apple’s next phase of software and services development for its ecosystem. Cupertino, California – Alongside the revamped Siri, Apple will introduce a new Extensions system that allows users to toggle between multiple AI models, including ChatGPT, Claude, and Gemini, each distinguished by a separate voice to clarify which system is responding. This multi-model framework departs from the prevailing industry trend of building fully proprietary frontier models and instead relies on a licensing deal with Google estimated at $1 billion per year. Industry analysts are closely tracking this approach, which emphasizes deep hardware integration and private cloud inference, and describe it as a neutral, “Swiss-style” stance amid intensifying competition among major AI providers.
