Apple Siri Upgrade Delays to iOS 26.5 and iOS 27 (AAPL)

Apple’s planned Siri enhancements are being pushed back due to testing issues, moving key features from iOS 26.4 to iOS 26.5 (May) and iOS 27 (September). Internal testing found the assistant struggles with query processing, latency, and complex commands, and sometimes falls back to OpenAI’s ChatGPT. The March 2026 target was reaffirmed internally despite a prior 2026 window and a previous hint of an early 2025 timeline. Apple is considering a preview mode for high-risk features and has included a notice in iOS 26.5 indicating some Siri improvements. Apple shares pared gains on the news, closing at $276.71, up 1.1% as of February 11, 2026, 14:52 ET. The new Siri, built on the Linwood architecture and Apple’s Foundations Models, is also integrating web search and image generation, with iOS 27 expected to bring a chatbot-style overhaul powered by Google servers under the “Campo” initiative.
