Apple's AI-Powered Siri Overhaul Delayed Again, May Not Arrive Until 2027

Apple's efforts to modernize Siri with generative AI have faced significant setbacks, with a fully conversational version of the assistant potentially pushed back to 2027. Despite promises made during the 2024 unveiling of Apple Intelligence, many core features remain unavailable as the company struggles to merge legacy systems with new large language model (LLM) architecture. Internal reports suggest a 'true' overhaul may not reach consumers until the release of iOS 20.

The Details

The current state of Siri is characterized by a 'two brains' architecture, where a legacy system handles basic commands like timers and phone calls, while a separate Apple Intelligence system manages complex queries. This fragmented approach has led to repeated delays in the goal of creating a unified, LLM-driven Siri. Robby Walker, Apple's Siri senior director, described the situation as 'ugly' and 'embarrassing' during a March 2025 all-hands meeting, noting that the technology only functions correctly between 66% and 80% of the time.

While Apple has partnered with Google to integrate Gemini into some Siri capabilities, the rollout of advanced features continues to slip. Voice-based control of in-app actions and expanded access to personal data—originally targeted for earlier updates—have been pushed to iOS 26.5 or even iOS 27. The pressure has been exacerbated by marketing campaigns and iPhone 16 commercials that promoted enhancements before they were technically viable.

To address these failures, Apple has brought in longtime executive Kim Vorrath as a 'project fixer' to stabilize the Siri group. High-level accountability for the turnaround now rests with AI chief John Giannandrea and software chief Craig Federighi. These internal shifts follow a period of instability that included the 2025 suspension of AI-generated news summaries after the system produced a false claim regarding the death of Luigi Mangione.

Despite the delays, the upcoming WWDC 2026 (June 8-12) is expected to focus heavily on the Siri overhaul for iOS 27. This version is rumored to introduce a new chatbot-like interface and a dedicated Siri application. Teasers in WWDC graphics suggest a 'Search or Ask' prompt featuring a glowing cursor within the Dynamic Island when the assistant is triggered.

Context

Siri launched in 2011 with the iPhone 4S and has historically struggled to keep pace with competitors like Google Assistant and Amazon Alexa. The 2024 announcement of Apple Intelligence was intended to close this gap, but the staggered release of features has left many users with tools that are viewed as only mildly helpful or inaccurate. Internal data suggests that overall usage of Apple Intelligence remains 'extremely low.'

Apple's insistence on a privacy-first approach—specifically its Private Cloud Compute architecture—has added a layer of complexity to development. While this system ensures stateless, attested processing in the cloud, it has slowed the iteration speed compared to rivals who utilize fully cloud-based AI models. Executives Craig Federighi and Greg Joswiak have admitted in interviews that the delay is partly due to Apple 'rebuilding from scratch.'

Meanwhile, the competitive landscape continues to shift. Amazon has already debuted Alexa+, a voice assistant featuring the very conversational capabilities and agentic AI tools that Apple is still attempting to perfect.

What's Next

The industry will be watching WWDC 2026 closely to see if Apple can deliver a concrete roadmap for iOS 27. The success of the new chatbot interface and support for third-party AI agents will be critical in determining whether Apple can reclaim leadership in the AI assistant space.

If the 'true' conversational Siri is indeed delayed until iOS 20 in 2027, Apple risks further eroding user trust and losing significant ground to Android's integrated Gemini ecosystem. The company's ability to balance its strict privacy mandates with the need for rapid AI iteration remains the primary hurdle for the Siri project.
