Google I/O kicks off May 19 at 1 PM ET with a Gemini-centric keynote. A new Gemini model (possibly Gemini 4.0 or Gemini Omni) is expected as the centerpiece, designed to rival GPT-5.5 and power Android AI app automation. Google has confirmed an Android XR glasses preview, and UI strings pointing to 'Gemini Omni' — a unified text/image/video generation model — were discovered in the Gemini interface. Google's VP called it a transition 'from an operating system to an intelligence system.'
