Key Points

  • A Bloomberg report says iOS 27 will introduce an internal “Extensions” feature that lets iPhone users choose third-party LLMs to power on-device generative AI features on demand.
  • The feature is intended to route generative AI access through Apple Intelligence experiences such as Siri, Writing Tools, and Image Playground, using installed apps as the entry point.
  • Bloomberg also reports the capability will extend to iPadOS 27 and macOS 27, and that Apple is currently testing models from Google and Anthropic.
  • ChatGPT’s status is unclear, but because it is currently the available model for users, it may remain an option.
  • The development lands as Apple’s AI strategy comes under scrutiny, with incoming leadership (John Ternus) expected to shape the company’s longer-term AI direction while Apple emphasizes AI-centric use of existing hardware rather than new infrastructure.

When iOS 27 is released later this year, iPhone users will reportedly have a lot of choice when it comes to which AI models they want to use on-device.

A new report from Bloomberg says that Apple plans to give users their pick of a number of third-party large language models that will be capable of powering various functions within the iPhone’s operating system. The new feature, dubbed “Extensions” internally, will allow users to “access generative AI capabilities from installed apps on demand, through Apple Intelligence features such as Siri, Writing Tools, Image Playground and more,” reads a message reportedly shown in test versions of the software.

The new capability will also be available for iPadOS 27 and macOS 27, the outlet writes, adding that models from Google and Anthropic are being tested now. Less clear is where ChatGPT stands. Since it is currently the model available to users, one implication is that it will remain a choice.

TechCrunch reached out to Apple for more information.

With long-serving CEO Tim Cook soon stepping down, Apple’s incoming top executive, John Ternus, is tasked with charting the future of the company — including its AI strategy. The company is widely perceived to be “behind” on AI, as it is not launching as many new AI services as some of its peers.

However, Apple is still bringing in a generous amount of AI-based revenue and its plan is less about spending money building out AI infrastructure and services than it is about turning its already existing hardware into an AI-centric experience for users.
