iOS 27 Will Let Users Choose Between Gemini, Claude, and More for AI Features

Apple is about to do something it almost never does: give users a choice about which AI powers their iPhone.

Starting this fall with iOS 27, iPadOS 27, and macOS 27, Apple will let users select from multiple third-party AI models � including Google's Gemini and Anthropic's Claude � to power core system features like Siri, Writing Tools, and Image Playground. The move, first reported by Bloomberg's Mark Gurman on May 5, represents the most significant opening of Apple's AI stack since the company launched Apple Intelligence in 2024.

How Extensions Work

Apple is calling the new capability "Extensions" internally. In test versions of iOS 27, Apple describes Extensions as a system that allows users to "access generative AI capabilities from installed apps on demand, through Apple Intelligence features such as Siri, Writing Tools, Image Playground and more."

The mechanism is straightforward: AI providers add Extensions support to their existing App Store apps. Once a compatible app is installed, users can set it as their preferred model in Settings. The selection is system-wide � choosing Claude or Gemini in one place means that model handles tasks across all supported surfaces. Ask Siri to summarize an email, use Writing Tools to rewrite a paragraph, or generate an image in Image Playground, and the chosen third-party model processes all of it.

Bloomberg reported that "users will be able to select from multiple third-party AI models for tasks like generating and editing text and images," with the changes slated for release this fall alongside iOS 27.

Gemini Gets a Privileged Position

The Extensions system arrives alongside a separate, deeper integration with Google. Apple has signed a deal � reportedly worth roughly $1 billion per year � to use a Gemini-based model as the native engine behind rebuilt Siri and Apple Intelligence features in iOS 27. This means Gemini occupies a dual role: it serves as the default backbone of Apple's own AI features while also being available as a user-selectable option through Extensions.

Claude, OpenAI's ChatGPT, and other providers arrive as opt-in additions through the App Store-gated mechanism that Apple controls entirely. ChatGPT, which Apple integrated as a fallback for world knowledge queries in iOS 18, will continue to be available but will no longer hold an exclusive position as the only third-party AI option on iPhone.

Voice Differentiation Signals Transparency

Apple is also introducing a subtle but telling feature: different voices for different AI models. According to Bloomberg's report, users will be able to choose different voices for Siri conversations powered by external models. Queries handled by Apple's own system would use one voice, while responses from third-party models such as Anthropic's Claude could use another.

This voice separation serves a dual purpose. It gives users a clear audio signal about which AI is actually responding to their query, and it preserves brand identity for third-party providers who otherwise operate invisibly behind Siri's interface.

The EU Regulation Shadow

While Apple has not explicitly tied Extensions to regulatory compliance, the timing is difficult to ignore. The European Commission issued preliminary findings on April 27 asking Google to open key Android features to third-party AI services under the Digital Markets Act. EU regulators have signaled they plan to expand DMA focus toward AI services, including whether certain AI assistants should be treated as virtual assistants subject to interoperability requirements.

Apple has already made sweeping changes to iOS in the EU under the DMA, including allowing third-party app stores, alternative browser engines, and contactless payment systems. Opening the AI layer to third-party providers follows the same pattern � building optionality before regulators mandate it.

Carolina Milanesi, a consumer technology analyst at Creative Strategies, noted in a previous assessment of Apple's platform strategy that Apple tends to move proactively on regulatory fronts where it can control the implementation rather than having specific technical requirements imposed externally.

Platform Competition Implications

The Extensions framework reshapes the competitive dynamics of the AI industry in several ways. For Google, having Gemini as both the default Apple Intelligence engine and a selectable Extension gives it unprecedented distribution on iOS � potentially reaching over a billion iPhone users. For Anthropic, it provides a direct path to consumer scale that Claude has largely lacked, given its primary traction in enterprise and developer markets.

For OpenAI, the change is more complex. ChatGPT loses its exclusive third-party position on Apple devices, and must now compete directly with Gemini and Claude within the same interface framework. The company will need to differentiate on model quality and features rather than relying on privileged platform access.

The broader signal is that AI model providers are becoming interchangeable components within platform ecosystems � similar to how search engines became selectable defaults in browsers. Apple is positioning itself not as an AI model company but as an AI platform company, taking a margin on distribution while letting providers compete on capability.

What Comes Next

Apple is expected to formally announce Extensions at WWDC on June 8, with iOS 27 shipping to consumers in September. The feature will likely launch with support from Google and Anthropic at minimum, with additional providers joining through the App Store over time.

For the 1.5 billion active Apple device users worldwide, the message is clear: the era of a single AI model powering your phone is ending. The question now is whether users will actually switch � or whether defaults, as they have throughout tech history, will determine the winners.
