Siri’s AI Overhaul Delayed Again

Apple’s Vision of a Smarter Siri Stumbles: Major Features Delayed as Internal Testing Reveals Persistent Flaws

In a development that has sent ripples through the tech world, Apple’s highly anticipated Siri overhaul has encountered significant setbacks during internal testing, forcing the company to delay key features and revise its ambitious timeline. What was once heralded as a transformative leap in artificial intelligence for Apple’s ecosystem now appears to be a more incremental evolution, with the company pushing several marquee capabilities out of the upcoming iOS 26.4 update and spreading them across later releases throughout 2025.

The Siri transformation, first unveiled with great fanfare at Apple’s Worldwide Developers Conference in June 2024, was positioned as Apple’s answer to the AI revolution that has swept through the tech industry. The company promised a Siri that would be more conversational, more contextually aware, and more deeply integrated with personal data across users’ Apple devices. However, according to a report from Bloomberg, the reality of internal testing has proven far more challenging than Apple’s optimistic projections suggested.

Sources familiar with the testing process reveal that the new Siri implementation continues to struggle with fundamental issues that have plagued voice assistants for years. The system frequently fails to process user queries reliably, experiences unacceptable delays in generating responses, and—perhaps most concerning for a company that prides itself on vertical integration—sometimes defaults to using OpenAI’s ChatGPT technology rather than Apple’s own AI infrastructure. These performance issues have proven stubborn, resisting multiple rounds of optimization and refinement.

The implications of these delays extend beyond mere inconvenience. Apple had positioned the enhanced Siri as a cornerstone of its AI strategy, promising features that would leverage personal context and cross-device integration in ways that competitors like Google Assistant and Amazon’s Alexa could not match. The personal data features, which would allow Siri to draw on information from Messages, Mail, Photos, and other native apps to provide more relevant and personalized responses, were particularly emphasized as differentiators that would set Apple apart in the crowded AI assistant market.

In response to these challenges, Apple has restructured its release strategy in a manner that suggests both pragmatism and acknowledgment of the technical hurdles involved. Engineers have been instructed to begin testing the new Siri capabilities on iOS 26.5, scheduled for release in May 2025, rather than the originally planned iOS 26.4 in March. This shift represents a delay of approximately two months for features that were already significantly overdue from the original early 2025 target.

Internal builds of iOS 26.5 reportedly include a settings toggle labeled “preview” for the personal data features, indicating that Apple intends to release these capabilities in a limited, beta-like capacity rather than as fully polished features. This approach allows Apple to gather real-world usage data and feedback while managing user expectations about the maturity of the technology.

Perhaps most intriguing is the development of a more ambitious chatbot-style Siri, codenamed “Campo,” which is being positioned as the next evolution beyond the personal context features. This version of Siri would be powered by Google servers and utilize a custom Gemini model, representing an unexpected partnership between two tech giants that have often positioned themselves as rivals in the AI space. Campo is currently targeted for inclusion in iOS 27, expected to debut at WWDC in September 2025.

The decision to potentially leverage Google’s AI infrastructure speaks to the challenges Apple faces in developing competitive AI capabilities in-house. While Apple has made significant investments in machine learning and AI research, the rapid advancement of large language models and the computational resources required to deploy them at scale have created a landscape where even the most well-resourced companies must make strategic decisions about building versus buying or partnering.

Industry analysts note that Apple’s struggles with Siri’s overhaul reflect broader challenges in the AI industry. The gap between demonstration-ready technology and production-ready systems that can handle the variability and complexity of real-world usage remains substantial. Companies across the tech sector have discovered that scaling AI systems to millions or billions of users while maintaining reliability, privacy, and performance is far more difficult than initial prototypes suggest.

For Apple, the delays also raise questions about the company’s competitive position in the AI assistant market. While Apple has traditionally excelled at hardware-software integration and privacy-focused design, the company has faced criticism for lagging behind competitors in AI innovation. The Siri overhaul was intended to address these concerns and reassert Apple’s leadership in user experience, but the extended timeline and feature reductions may instead reinforce perceptions of Apple as playing catch-up in the AI race.

The impact on Apple’s ecosystem could be significant. Many of the most anticipated features of the enhanced Siri were designed to work seamlessly across Apple devices, from iPhones and iPads to Macs and Apple Watches. The delay in these capabilities means that Apple’s ecosystem advantages—often cited as a key differentiator for the company—will remain underutilized for the foreseeable future.

Looking ahead, the tech community will be watching closely to see how Apple manages the rollout of these delayed features and whether the company can deliver on its promises of a truly intelligent, context-aware assistant. The partnership with Google on the Campo project suggests that Apple may be willing to embrace strategic collaborations to achieve its AI goals, a departure from its traditionally insular approach to technology development.

As the AI landscape continues to evolve at a breakneck pace, Apple’s journey with Siri serves as a reminder that even the most valuable and resourceful companies face significant challenges in bringing advanced AI to market. The coming months will reveal whether Apple can overcome these obstacles and deliver on its vision of a smarter, more capable Siri—or whether the company will need to further revise its expectations and timeline for this critical piece of its AI strategy.
