This is a notable step, as the company had committed to upgrading Siri to understand personal context and take action in the application since last year, but officially postponed the plan in March.
Under the new proposal, Apple has asked OpenAI and Anthropic to train versions of AI models that can run on the Private Cloud Compute system - security servers designed by Apple, operated on its own chips. The company has previously used the system for some AI features that cannot be processed locally.
Currently, Apple is using OpenAI's ChatGPT for some components of the Apple Intelligence platform. However, Siri's complete reliance on a third party will be a major shift, as much of the company's AI technology is now internally built under the name Apple Foundation Models.
At the 2025 Worldwide Developers Conference (WWDC), Apple also announced that it will open its platform models to outside developers. Considering collaborating with OpenAI or Anthropic shows a change in internal strategy.
If this becomes a reality, the AI version of Siri will be somewhat similar to Samsung's Galaxy AI strategy, which combines custom software with Google's Gemini model. Apple may still switch back to using internal technology in the future, as the company did when it replaced Google Maps with Apple Maps in 2012.
The new Siri version is not expected to be released before 2026. Meanwhile, this fall, Apple will release a series of features with not too complicated AI elements along with iOS 26, iPadOS 26, and macOS 26.
