Siri’s AI Evolution Faces Internal Criticism
Apple’s ambitious project to transform Siri into a competitive AI-powered assistant is encountering significant headwinds, according to internal reports from the company’s engineering teams. Sources familiar with the matter indicate that early builds of iOS 26.4, scheduled for spring 2026 release, are showing concerning performance limitations in Siri’s redesigned architecture.

The concerns emerge as Apple races to close the gap with competing AI assistants from Google, Amazon, and emerging players in the artificial intelligence space. The company had previously publicly committed to a complete architectural overhaul for Siri, but the transition appears to be proving more challenging than anticipated.
Architectural Growing Pains
Apple’s Senior Vice President of Software Engineering, Craig Federighi, had previously explained the necessity of moving from Siri’s V1 to V2 architecture, stating: “We found that the limitations of the V1 architecture weren’t getting us to the quality level that we knew our customers needed and expected… if we tried to push that out in the state it was going to be in, it would not meet our customer expectations or Apple standards.”
Despite this strategic pivot, the V2 architecture is now experiencing what appears to be typical teething problems associated with complex AI system development. Engineers have reportedly identified performance inconsistencies across different applications and critical use cases, including sensitive operations like banking transactions where reliability is paramount.
Knowledge Integration Challenges
At the heart of Siri’s redesign is the work being done by Apple’s Answers, Knowledge and Information (AKI) team, which focuses on enabling the voice assistant to pull information directly from the web – a capability that has become standard among modern AI systems. This approach mirrors functionality that OpenAI’s language models and other AI systems have demonstrated effectively.
The timing of these performance concerns coincides with the surprising departure of Ke Yang, who was appointed head of the AKI team just weeks before announcing his move to Meta Platforms Inc. While Apple hasn’t commented on the specific reasons behind Yang’s exit, the development raises questions about the project’s trajectory and the competitive pressures facing Apple’s AI initiatives.
Broader Industry Context
Apple’s Siri struggles occur against a backdrop of rapid AI advancement across the technology sector, where companies are investing heavily in next-generation artificial intelligence capabilities. The pressure to deliver a competitive AI assistant has never been higher for Apple, particularly as consumers increasingly expect sophisticated, context-aware interactions from their digital helpers.
The company’s challenges also reflect wider market dynamics and technological hurdles facing even the most established tech giants as they navigate the complex landscape of AI development and deployment.
Strategic Implications
Apple’s methodical approach to AI development has sometimes contrasted with the more rapid release cycles of competitors. However, the company has historically prioritized refinement and integration over being first to market. As the iOS 26.4 development continues, engineers are reportedly focusing on several key areas:
- Cross-application consistency – Ensuring Siri performs reliably across Apple’s ecosystem and third-party apps
- Critical scenario reliability – Maintaining performance in high-stakes situations like financial transactions
- Knowledge retrieval accuracy – Improving the system’s ability to fetch and present accurate web-sourced information
- Response latency – Reducing delay in Siri’s responses to match user expectations
These developments in Apple’s AI strategy are part of broader global technology trends reshaping how companies approach artificial intelligence implementation and integration.

Looking Ahead
With approximately two years until the expected release of iOS 26.4, Apple engineers have time to address the identified performance issues. However, the internal concerns highlight the substantial technical challenges involved in rebuilding a voice assistant from the ground up while maintaining the seamless user experience for which Apple is known.
The situation also illustrates how even well-resourced technology leaders can face significant obstacles in the competitive AI landscape. As regulatory and competitive pressures continue to shape the technology sector, Apple’s ability to deliver on its Siri promises will be closely watched by industry observers and consumers alike.
These internal challenges at Apple reflect the complex interplay between innovation, execution, and market expectations that defines today’s technology landscape. How Apple navigates these Siri development hurdles could significantly influence its competitive position in the increasingly AI-driven consumer technology market.
