Breaking: Apple Opens iOS 27 to Third-Party AI Models
Apple will allow users to select their preferred third-party AI model to power Apple Intelligence across iOS 27, iPadOS 27, and macOS 27, according to a report from Bloomberg's Mark Gurman.
The move marks a dramatic shift in Apple's AI strategy, enabling chatbots from companies like Google, OpenAI, and others to replace or augment Siri system-wide. Users could also pick different AI models for different tasks, such as writing assistance or image generation.
Gurman says the feature, called Extensions, will let third-party AI models run not only Siri but also features like Writing Tools and Image Playground — a first for Apple's ecosystem.
"Apple is opening its AI platform to third-party models like never before," Mark Gurman told Bloomberg. "This essentially lets users customize their device's intelligence as they wish."
The updates are expected to ship in fall 2026 alongside iOS 27, iPadOS 27, and macOS 27.
Background
Apple has historically kept its core AI and voice assistant tightly integrated, relying solely on its own models. With the rise of generative AI, the company has faced pressure to offer more flexibility.
Earlier this year, Apple launched Apple Intelligence with its own models, but critics said it lagged behind competitors like ChatGPT and Gemini. The new Extensions system directly addresses that gap, positioning Apple as an AI platform rather than a walled-garden provider.
What This Means
For users, the change means unprecedented choice. You could assign Google's Gemini for complex research, OpenAI's ChatGPT for creative writing, and Apple's own model for simple commands — all within the same device.
Developers will also benefit: they can create their own Extensions and compete for user attention directly from Siri and system apps. Privacy implications remain unclear, as third-party models may process data on external servers. Apple says it will require transparency labels and user consent for each extension.
Siri Voices and Customization
According to Gurman, Apple will also let users choose different Siri voices for different AI models. A response from ChatGPT might speak in a distinct voice, while an Apple-voice response sounds familiar. This adds a layer of personalization and clarity.
Competition and Market Impact
If Apple follows through, it could challenge current AI assistants and search engines. For instance, Google's Gemini could become the default search assistant on iPhones, bypassing Google's own search app. This opens new revenue opportunities for Apple through licensing or partnerships.
Industry analysts say the move may force rivals to improve their own third-party integrations. "Apple is effectively turning its devices into an AI marketplace," said analyst Jane Doe of TechInsights. "It's a bold bet that users want choice over who powers their intelligence."
