January 25, 2025 – In a recent blog post, Bloomberg’s Mark Gurman revealed an internal Apple memo that sheds light on the company’s focus in the AI field for 2025. According to the leaked memo, Apple’s AI head John Giannandrea has outlined the team’s priorities for the year ahead.
The memo highlights that the main emphasis for 2025 will be on enhancing Siri’s underlying infrastructure. This suggests that Apple is rebuilding Siri’s core technology to pave the way for more powerful features and a smoother user experience in the future.
Another key area of focus mentioned in the memo is refining the company’s existing AI models. This aligns with Apple’s consistent approach of incremental iterations and improvements. For instance, the memo points to recent issues with the notification summary feature, which underscores the need for refining AI models.

As part of these efforts, Apple has temporarily disabled the notification summary function for certain app categories in iOS 18.3. This move is likely aimed at boosting the accuracy and stability of the AI models powering this feature.
Gurman previously reported that Siri is undergoing a significant transformation behind the scenes, with a goal to become “LLM Siri.” This new version of Siri is anticipated to launch in the spring of 2026, possibly with iOS 19.4. This development aligns perfectly with Giannandrea’s stated priorities for the year.
Fine-tuning AI models is also crucial, given the recent glitches in the notification summary feature. Apple’s decision to temporarily suspend notification summaries for specific app categories in iOS 18.3 suggests they are working on refining the AI algorithms that drive this functionality.
