The deal could see Apple paying Google $1 billion a year to power Siri with the latter’s 1.2 trillion parameter-Gemini model. For comparison, Apple’s own cloud-based model has 150 billion parameters, while the on-device model, designed for local processing, has just three billion.
The report indicates that the custom Gemini model will manage Siri’s summariser and planner functions, while Apple’s in-house models will handle other features. As the Gemini model runs on Apple’s Private Cloud Compute servers, user data is not shared with Google. This is a significant distinction between Apple’s privacy-first stance on AI and the competition.
The partnership is unlikely to be long-term as Apple continues to work on its cloud-based AI model. It aims to release a one-trillion-parameter model as soon as next year. The “more personalised Siri” powered by Gemini is on track to launch by spring 2026.
