Apple Intelligence: Apple's new AI push is built into every facet of iPhone, iPad, and Mac, with features that summarize notifications, proofread messages, and more. It can also generate content such as generative pictures in Messages. Apple's AI push also includes integration with ChatGPT 4.0 on iPhone, iPad, and Mac.

Siri, Apple's voice assistant, is expected to undergo a significant upgrade in the context of the new AI developments announced at WWDC 2024. The integration of generative AI capabilities into Siri aims to make the voice assistant more conversational and capable of handling tasks such as setting timers, creating calendar appointments, adding items to Reminders, and summarizing text.
Siri's generative AI version of Apple's Ajax-based model is expected to be announced at WWDC, adding more personalization and natural conversation capabilities to Siri1. This upgrade will bridge the gap between artificial and human-like interactions. Additionally, efficient management between devices, such as various Apple iPhones, is anticipated.
A new Apple-specific creation service is also expected to be added to Siri. While details about this service are still speculative, it could relate to expanded Siri-based shortcuts capabilities rumored for iOS 18. This service might offer unique functionalities, leveraging Siri's AI capabilities for creative or productivity tasks.
Furthermore, the integration of linkage services between various external services is another expected development for Siri. Apple is reportedly working on developing linkages for Siri to connect to different external services, potentially through an API. This move could significantly expand Siri's capabilities, allowing it to interact with a broader range of applications and services, enhancing its utility for users.
Lastly, some services or functions may differ between subscription services. Apple's new AI features, including those for Siri, may be differentiated based on subscription service status. This approach suggests a monetization strategy for the more advanced capabilities of Siri, although the exact details are yet to be confirmed.
In summary, Siri is expected to become more personal, conversational, and integrated across Apple devices, enhancing the overall user experience. With the addition of an Apple-specific creational service and the potential for expanded external service linkages, Siri is poised to become more versatile and useful than ever before.
