Apple's highly anticipated Siri upgrade, originally slated for 2024, has been repeatedly delayed and is now expected in March 2026 with iOS 26.4. Internal issues, including a buggy hybrid architecture, caused setbacks and led to executive-level changes. The project, now under new leadership, is undergoing a complete rebuild. While Apple aims for a more advanced, copilot-like Siri in the future, the immediate focus is on the 2026 release, though further delays remain a possibility.
