Apple’s long-awaited AI upgrade for Siri is expected to launch with iOS 26.4, likely arriving in March. Based on past iOS x.4 releases and current beta timelines, a late-March rollout seems most probable, though an earlier March release is possible if testing begins sooner.
The update will introduce a rebuilt, LLM-based Siri capable of more advanced, chatbot-like assistance, along with delayed features such as App Intents, personal context awareness, and onscreen understanding. This marks Siri’s biggest overhaul yet, with high expectations after years of delays.
