SAN FRANCISCO — Apple plans to monetize its new artificial intelligence features, including an upgraded Siri, through a subscription model tied to iCloud. CEO Tim Cook said the strategy positions Apple's hybrid AI approach as a competitive weapon and signals deeper integration of AI into its services ecosystem.

The hybrid model combines on-device processing with cloud-based capabilities for more complex AI tasks. Running some functions on-device improves user privacy and reduces latency; offloading intensive computations to Apple's data centers enables more sophisticated models. That architecture contrasts with purely cloud-based AI offerings from rivals.

The shift to paid AI via iCloud fits Apple's long-term push to grow its high-margin services business. Services revenue reached $85 billion in fiscal 2023, representing nearly 22 percent of total sales. Expanding subscriptions is critical as global smartphone sales mature.

Apple shares closed at $308.91, down 7.4 percent, though the company has not yet disclosed full details of the AI monetization plan.

Apple enters a market where rivals already charge for advanced AI. Microsoft offers Copilot Pro as a $20-per-month add-on to Microsoft 365. Google integrates Gemini into its Workspace tiers, while Amazon provides enterprise-focused AI through AWS.

Apple's core advantage is its integrated hardware-software ecosystem and an installed base of more than 2.2 billion active devices — a direct distribution channel for any new service. The company also emphasizes user privacy, a potential differentiator as scrutiny of data handling grows.

Monetizing AI through iCloud draws on the higher gross margins of software and cloud services relative to hardware. Recurring subscription revenue can fund continued investment in AI research and data center capacity.

Given Apple's user base, even a modest conversion rate to paid AI subscriptions could generate substantial new revenue. iCloud already serves hundreds of millions of users for storage and backups, giving the company an existing billing relationship to build on.

Cook's statement comes as he prepares to leave the CEO role, setting a strategic direction for his successor. AI and services are now central to Apple's growth beyond hardware.

The primary challenge is persuading users to pay for features that competitors may offer free or at lower cost. Adoption will depend on the perceived value of Siri AI's capabilities. Subscription fatigue and a crowded AI market pose additional risks.

Apple has not disclosed pricing tiers or a launch date. The company typically unveils major software updates at its annual Worldwide Developers Conference.
