Apple iOS 27 Opens Door to Third-Party AI Models

Apple is preparing a major shift in its AI strategy by allowing users to choose third-party AI models across its operating systems starting this fall. According to Bloomberg's Mark Gurman, iOS 27, iPadOS 27, and macOS 27 will let users select from multiple AI providers for core features like text generation, editing, and image creation — breaking ChatGPT's current monopoly as Apple's sole third-party AI partner.

Key Takeaways

• Apple will allow users to choose third-party AI models in iOS 27, iPadOS 27, and macOS 27 this fall
• Google and Anthropic are already undergoing internal integration testing with Apple
• The feature is internally called 'Extensions' and will be configurable through the Settings app
• AI providers must have an App Store presence to qualify for integration
• This expands beyond Siri to cover writing tools, image generation, and other Apple Intelligence features
• ChatGPT will no longer be the only third-party AI option on Apple devices

From ChatGPT Exclusivity to an AI Marketplace

When Apple launched Apple Intelligence in 2024, the company took a cautious approach to third-party AI integration. OpenAI's ChatGPT was the only external model available, and its use was limited to specific features like Siri, Writing Tools, and Image Playground. Users had no choice — if they wanted third-party AI capabilities on their Apple devices, ChatGPT was the only game in town.

That exclusivity is about to end. Apple's decision to open up its ecosystem to multiple AI providers represents a fundamental philosophical shift. Rather than picking winners in the AI race, Apple is positioning itself as a platform — much like it did with the App Store — where users decide which AI best serves their needs.

This move mirrors a pattern Apple has followed before. The company initially restricted default browser and email app choices on iOS before eventually opening those selections to third-party alternatives under regulatory and competitive pressure.

Google and Anthropic Lead the Integration Pack

Sources familiar with the matter reveal that Apple has already begun internal integration testing with 2 major AI players: Google and Anthropic. Google likely brings its Gemini family of models to the table, while Anthropic would offer its Claude models — both of which are considered top-tier competitors to OpenAI's GPT series.

The selection of these 2 companies is strategic. Google brings massive scale, deep Android competition knowledge, and an existing relationship with Apple through the Safari search deal reportedly worth over $20 billion annually. Anthropic, backed by Amazon and Google themselves, has built a reputation for safety-focused AI that aligns well with Apple's privacy-first messaging.

Apple's spokesperson declined to comment on the report. However, the company's internal builds already show the infrastructure taking shape under the codename 'Extensions.'

How 'Extensions' Will Work in Practice

Internally, Apple refers to this third-party AI capability as 'Extensions.' The system is designed to give users granular control over which AI model powers different features on their devices. Here is what we know about the implementation so far:

• Users will access model selection through the Settings app
• Each AI feature category (text, images, etc.) can potentially use a different provider
• AI providers must have an approved App Store application to be eligible
• The system builds on Apple's existing Apple Intelligence infrastructure
• Users will likely need accounts with their chosen AI providers
• Apple appears to be building a standardized API layer for model integration

This approach is notably different from simply allowing users to switch chatbots in Siri, which Gurman first reported in March 2025. The new 'Extensions' framework goes much deeper, embedding third-party AI capabilities into the core operating system experience across writing, image generation, and potentially other creative and productivity tasks.

Strategic Implications for the AI Industry

Apple's move carries enormous weight in the AI industry. With over 1.5 billion active Apple devices worldwide, the ability to be a default or selectable AI provider on iOS represents a distribution channel that no AI company can afford to ignore.

For OpenAI, this is a double-edged sword. While ChatGPT gained tremendous visibility through its Apple partnership, the company now faces direct competition on a platform where it previously had exclusive access. OpenAI will need to compete on merit — model quality, speed, and user experience — rather than relying on its privileged position.

For Google, this represents a fascinating competitive dynamic. The company already competes with Apple on the hardware and OS level through Android, but now it could become a key AI supplier within Apple's ecosystem. Google's Gemini models could reach hundreds of millions of iPhone users who would never switch to an Android device.

For Anthropic, the opportunity is transformative. Claude has earned strong reviews from developers and enterprise users, but its consumer reach lags behind ChatGPT and Gemini. An Apple integration could catapult Anthropic into mainstream consumer awareness virtually overnight.

What This Means for Users and Developers

For everyday users, the practical benefits are significant:

• Choice and flexibility: Users can pick the AI model that best suits their workflow
• Competition drives quality: Multiple providers competing on Apple's platform should improve model performance and lower costs
• Privacy options: Users concerned about data handling can choose providers whose policies they trust
• Specialized capabilities: Different models excel at different tasks — users could pick the best model for each use case

For developers, the implications are equally profound. App makers who have built on Apple Intelligence will need to consider how their applications interact with multiple AI backends. The standardized 'Extensions' framework could also create new opportunities for smaller AI companies to reach Apple's massive user base, provided they meet App Store requirements.

The requirement for AI providers to maintain an App Store presence is a clever gatekeeping mechanism. It ensures Apple retains some control over quality and compliance while still opening the ecosystem to competition.

Regulatory Context and Market Pressures

Apple's decision does not exist in a vacuum. The company faces increasing regulatory scrutiny worldwide, particularly from the European Union's Digital Markets Act (DMA), which has already forced Apple to allow alternative app stores and payment systems in Europe.

While there is no direct regulatory mandate requiring Apple to offer third-party AI choices, the broader regulatory climate favoring interoperability and user choice likely influenced this decision. By proactively opening its AI platform, Apple may be getting ahead of potential future regulations targeting AI gatekeeping.

The move also addresses criticism that Apple's AI capabilities have lagged behind competitors. By letting users plug in Google's Gemini or Anthropic's Claude, Apple effectively outsources the AI arms race while maintaining control over the user experience and hardware integration that it does best.

Looking Ahead: The Fall 2025 Launch and Beyond

Apple is expected to formally announce iOS 27 at WWDC 2025 in June, with a public release following in September alongside new iPhone hardware. The AI model selection feature will likely be one of the headline announcements, given the intense industry and consumer interest in AI capabilities.

Several questions remain unanswered. Will Apple take a revenue cut from AI subscriptions initiated through its platform? How will the company handle data privacy across multiple AI providers? Will smaller AI startups like Mistral, Cohere, or xAI eventually join the roster?

The competitive dynamics could also shift rapidly. If Apple's 'Extensions' framework proves successful, it could pressure Google to offer similar AI model choices on Android — creating a true cross-platform AI marketplace. Samsung has already experimented with multiple AI providers through its Galaxy AI features, but nothing at the system-level depth Apple appears to be planning.

One thing is clear: Apple's decision to open its AI platform to third-party models marks the beginning of a new era in consumer AI. The company that once insisted on controlling every aspect of the user experience is now betting that choice — not exclusivity — is the winning strategy in the age of artificial intelligence. For the billion-plus users in Apple's ecosystem, that bet could pay off handsomely.
