Apple Engineers Reportedly Voice Concerns Over Apple Intelligence-Powered Siri Ahead of Launch

As Apple prepares to bring its most ambitious version of Siri to users next year, reports suggest that the project isn’t entirely smooth sailing behind the scenes. Some engineers involved in developing the Apple Intelligence-powered assistant have raised concerns about its current reliability and responsiveness, according to Bloomberg’s Mark Gurman.

The upgraded Siri, expected to debut with iOS 26.4 in the spring, represents a complete rethinking of how Apple’s voice assistant functions. Instead of simple commands, the new system is designed to interpret context, understand what’s happening on-screen, and handle multi-step tasks across apps. Apple previewed the experience at WWDC 2024, showcasing examples such as pulling flight details from an email or referencing a calendar invite mentioned in a text message, tasks meant to make Siri feel more capable and human-like.

However, despite visible progress, development has proven challenging. The rollout was initially targeted for 2024 but was postponed as engineers continued refining accuracy, natural-language understanding, and integration with Apple Intelligence. Internally, some developers reportedly remain skeptical about whether the feature set is ready for a large-scale launch.

Apple CEO Tim Cook previously described the new Siri as a cornerstone of the company’s AI ambitions, emphasizing privacy and on-device processing as defining advantages over competitors. With iOS 26.4 expected around March or April, Apple still has time to address lingering issues, but the success of the assistant’s debut may hinge on whether it can deliver the seamless intelligence Apple has been promising for years.
