Apple has spent most of its existence doing one thing better
than almost any other company in technology: controlling the experience inside
its ecosystem. The hardware, the software, the default applications, the entire
stack from chip to interface. All Apple. All the time. That philosophy built
one of the most valuable companies in history and one of the most loyal user
bases in consumer technology.
According to a report by Bloomberg's Mark Gurman published in the first week of May 2026, Apple is preparing to open iOS 27 to third-party AI models from OpenAI, Google, and Anthropic. For the first time, iPhone users will be able to choose which AI powers the features they use every day, from writing tools and Siri to image generation and smart suggestions. The feature is reportedly being called Extensions internally.
What Is Actually Being Reported
The Bloomberg report describes a mechanism that works as follows: AI providers will opt into the system by adding compatibility through their App Store applications. Once integrated, users will be able to select which AI service powers specific Apple Intelligence features directly from their device Settings. The features potentially opening to third-party models include Siri, Writing Tools, and Image Playground, and the capability will apply across iOS 27, iPadOS 27, and macOS 27.
Apple has reportedly already been testing integrations internally with Google and Anthropic. OpenAI's position in the arrangement is more uncertain. ChatGPT has been the only external AI model available through Apple Intelligence since it launched, but the relationship between Apple and OpenAI has become strained partly due to OpenAI's efforts to recruit Apple engineers for its own hardware ambitions. Opening the platform to Google and Anthropic diversifies Apple's AI partnerships and reduces dependence on a company that is increasingly a competitor in the device space.
Why Apple Is Doing This
Understanding the decision requires understanding Apple's position in the AI race right now, which is not as comfortable as its dominance in hardware might suggest.
Apple Intelligence Has Underdelivered
Apple Intelligence launched with considerable fanfare and underwhelmed in practice. Siri remains widely regarded as the weakest of the major voice assistants on questions requiring genuine reasoning or current knowledge. Google's Gemini and Anthropic's Claude have both demonstrably outperformed Apple's internal models on most language tasks. Rather than competing directly to build the most capable foundation model, Apple appears to be shifting to a platform strategy: let the best models compete on Apple's hardware, and let Apple focus on what it has always done best, the device experience, the privacy architecture, and the ecosystem integration.
The
OpenAI Relationship Has Soured
ChatGPT
was positioned as the flagship external AI partner when Apple Intelligence
launched. Usage has reportedly been more limited than either company
anticipated. OpenAI's active recruitment of Apple engineers to build its own AI
hardware devices puts it in direct competition with Apple's core business.
Opening the platform to Google and Anthropic is both a diversification and a
signal that Apple is not willing to be dependent on a single AI partner that is
becoming a competitor.
Leadership Transition Changes the Strategic Context
Apple's long-serving chief executive Tim Cook is stepping down. His incoming successor John Ternus inherits a company perceived by many observers to be behind on AI. A bold platform opening in iOS 27 would send a clear signal that the new leadership is prepared to make the structural changes needed to remain competitive, even if those changes mean surrendering some of the control Apple has historically guarded most carefully.
What This Means in Practice
For users who already have ChatGPT, Claude, or Gemini installed on their devices, Extensions in iOS 27 would mean those tools become available system-wide rather than only within their own apps. Asking Siri a question, drafting an email in Writing Tools, editing a photo with AI suggestions: all of these could be powered by your preferred AI model rather than Apple's built-in system. For professionals who have already settled on Claude as their preferred tool for nuanced work, having it available as the default AI engine across their Apple device rather than only in the Claude app would represent a meaningful daily workflow improvement.
Privacy-conscious users face the most nuanced consideration. Apple has built significant goodwill on privacy, and that goodwill is part of its brand. Routing queries through third-party AI providers means those providers' privacy policies apply to that data. Apple has indicated it will clarify that it is not responsible for content generated by third-party models, which is a legally sensible position but one that transfers meaningful privacy decisions to the user. Understanding what each provider does with your data before selecting them as your default AI is worth doing before iOS 27 arrives.
What About Siri Specifically
Siri is getting more than third-party model support. The Bloomberg report also describes a redesigned Siri arriving in iOS 27 as a standalone app with a full chat interface, rather than the overlay experience that has defined Siri for a decade. A dedicated Siri mode in the camera app will replace the current Visual Intelligence feature, and users will reportedly be able to assign different voices to different AI models so responses from Apple's own system sound distinct from those handled by Gemini or Claude.
This is effectively a ground-up reimagining of Apple's AI assistant strategy. Whether it succeeds will depend heavily on execution, an area where Apple's AI track record in recent years has been less impressive than its hardware and design record. The announcement at WWDC 2026, which the AI Vanguard will cover in full, will reveal how much of what Bloomberg reported makes it to the public stage.
The AI Vanguard Take: This is the right strategic move at the right time. Apple's internal AI capability has not kept pace with its competitors. Opening the platform to the best models in the world, rather than insisting on building everything in-house, gives two billion device users access to genuinely capable AI through the experience they already trust. Apple's bet is that controlling the device is more valuable than controlling the AI. Given the trajectory of the AI model race, that bet looks increasingly correct.
Frequently Asked Questions
When will iOS 27 be available?
Apple
typically announces new iOS versions at WWDC in June with a public release in
September. If iOS 27 follows the standard cycle it would be announced in June
2026 and publicly available in September 2026. The AI Vanguard will cover the
WWDC announcement in full when it happens.
Will I have to pay for third-party AI models on my iPhone?
This
depends on the provider and the model. The free tiers of ChatGPT, Claude, and
Gemini are available at no cost. Premium tiers with enhanced capabilities
require a monthly subscription. Apple has not confirmed how billing and access
tiers for third-party models will work within the Extensions system.
What happens to my privacy when I use a third-party AI through Apple?
When a query is handled by a third-party model rather than Apple's own system, the privacy policy of that provider applies to that data. Users should review the privacy policies of any AI model they choose to integrate. The Day 5 post on AI data privacy on The AI Vanguard covers what the major providers actually do with your data.
