Apple is currently testing an updated version of Siri that utilizes OpenAI's ChatGPT. Users have reported that this integration has made Siri smarter and better equipped to handle complex queries. However, this reliance on external technology underscores the need for Apple to develop its own solution.


Insiders reveal that Apple’s engineers are developing an in-house LLM to replace ChatGPT within Siri. This new functionality is expected to be announced at the Worldwide Developers Conference (WWDC) in summer 2025, with its integration into iOS planned for 2026.


Although Apple introduced AI-powered features in its operating systems in 2024, it still lags behind competitors. Google has already incorporated its Gemini language model into Android, and Microsoft has deeply integrated ChatGPT-based features into its ecosystem. Apple's move to create its own LLM highlights its efforts to catch up in the competitive AI landscape.

By developing its own LLM, Apple aims to offer a more advanced, context-aware Siri that can better serve users' needs. This initiative reflects Apple’s broader strategy to enhance its AI capabilities while maintaining control over its core technologies.
