iOS 27 to let users choose AI models for Siri and Apple Intelligence

Apple is preparing a major shift in its AI strategy with iOS 27, introducing a new system that allows users to select their preferred AI model for core features like Siri, Writing Tools, and Image Playground. According to Bloomberg’s Mark Gurman, the upcoming operating system updates—iOS 27, iPadOS 27, and macOS 27—will support "Extensions," enabling third-party chatbots to power Apple Intelligence features system-wide. This move marks a significant departure from Apple’s traditionally closed ecosystem, offering users greater flexibility in how they interact with AI-driven functions.

Apple Intelligence gets an open door for third-party AI models

For years, Apple’s AI capabilities have been tightly integrated with its proprietary systems, limiting external options for users seeking alternatives. With iOS 27, that changes. The update will introduce a framework where third-party AI models, referred to as Extensions, can be selected to handle tasks currently managed by Apple’s native AI. This includes not only Siri but also features like Writing Tools, which assist with drafting and editing text, and Image Playground, which generates visuals from text prompts.

The integration extends beyond mere functionality. Users will also have the option to pair different Siri voices with specific AI models. For example, someone might prefer a more conversational tone for one model while using a concise, professional voice for another. This level of customization ensures that the AI experience aligns more closely with individual preferences, whether for productivity, creativity, or accessibility.

How Apple’s Extensions framework works

While Apple has not yet released detailed technical documentation, Gurman’s report suggests the Extensions framework will operate similarly to existing app extensions on iOS. Developers will need to meet Apple’s compatibility and security standards before their AI models can be listed in the App Store for user selection. The process likely involves:

• - Meeting performance benchmarks for latency and accuracy
• - Ensuring data privacy compliance with Apple’s policies
• - Integrating seamlessly with Apple’s APIs for Siri and other features

Once approved, users will be able to toggle between different AI models in the Settings app, much like switching between keyboards or input methods. This approach balances Apple’s commitment to quality and security with the growing demand for user choice in AI tools.

What this means for the future of Apple’s AI

The introduction of third-party AI models in iOS 27 signals a strategic pivot for Apple, which has historically prioritized in-house development to maintain control over its ecosystem. By opening the door to external providers, Apple acknowledges the rapid evolution of AI technology and the diverse needs of its user base. This could encourage innovation among third-party developers while also fostering healthy competition within Apple’s ecosystem.

For users, the benefits are clear: greater flexibility, the ability to tailor AI interactions to personal preferences, and access to cutting-edge models that may outperform Apple’s current offerings in specific tasks. However, the success of this initiative will depend on the quality and reliability of the Extensions available, as well as Apple’s ability to maintain a seamless and secure user experience.

As iOS 27 approaches its expected release this fall, Apple’s AI strategy is entering a new phase—one that embraces openness while still prioritizing the polished, integrated experience users expect from the company.
