Apple employees have raised internal concerns about the performance of the revamped Siri ahead of its expected release with iOS 26.4 in early 2026. Despite major upgrades under Apple Intelligence, engineers worry about readiness, prompting scrutiny over the voice assistant’s reliability, context awareness, and in-app control features.

Concerns mount over Siri’s readiness

Apple’s much-anticipated overhaul of Siri, powered by its new Apple Intelligence framework, is facing internal scrutiny just months before its scheduled release with iOS 26.4. According to reports from Bloomberg and MacRumors, several Apple engineers have expressed doubts about Siri’s performance in early builds, citing issues with responsiveness, contextual accuracy, and integration across apps.

Originally slated for release with iOS 18.4 in 2024, the new Siri was delayed due to quality concerns. Apple’s Senior Vice President of Software Engineering, Craig Federighi, acknowledged earlier this year that the assistant had not met internal benchmarks and required further refinement. Now, with a tentative rollout expected in March or April 2026, pressure is mounting to deliver a polished product.

What’s new in Siri 2.0

The revamped Siri is designed to be smarter and more intuitive, featuring three core capabilities: on-screen awareness, personal context, and in-app controls. These upgrades aim to make Siri more proactive and useful in everyday tasks, such as checking flight details, managing calendar events, or navigating apps with voice commands.

However, insiders suggest that while the vision is ambitious, the execution still lags behind competitors. Some engineers reportedly fear that if Siri’s performance doesn’t improve, it could lead to further delays or even reputational damage for Apple’s AI efforts.
