During Tim Cook's last earnings call in his capacity as Apple's CEO, artificial intelligence (AI) took center stage for investors. Apple's management team discussed how Siri AI could drive demand for iPhone upgrades and the cost implications tied to AI investments. For the first time, they also hinted that Siri AI might transition to a paid model in the future. Apple intends to impose usage limits on the free version of Siri AI, meaning that heavy users might have to subscribe to iCloud+ services, although the exact pricing structure remains to be finalized. Furthermore, certain Apple Intelligence features will implement a tiered access approach, granting iCloud+ subscribers higher usage limits or exclusive capabilities. iOS 27, which incorporates Siri AI, is anticipated to roll out later this year, compatible with devices like the iPhone 15 Pro and subsequent models. However, owing to regulatory considerations, its launch in Europe and mainland China will be delayed in the near term. Apple is actively exploring new subscription-based avenues to monetize its AI capabilities.
