Apple Develops Internal ChatGPT-Like App to Test Siri Overhaul

Apple has developed an internal application resembling ChatGPT to assist engineers in testing a revamped version of Siri. This tool is designed exclusively for internal use and will not be released to the public. The application facilitates the evaluation of new Siri features, including improved contextual awareness, enhanced inter-app functionality, and deeper integration with personal data.

The interface of the app mirrors that of other chatbot applications, organizing multiple conversations across various topics. It is capable of remembering and referencing past interactions, supporting extended dialogues. Apple has been working on a more intelligent version of Siri since the launch of iOS 18. Initially, the company planned to introduce an AI-enhanced Siri as part of the update but postponed the release to 2026 due to unmet standards.

The original plan for Apple Intelligence Siri was abandoned in favor of a comprehensive overhaul using second-generation architecture, accelerating the transition to large language models (LLMs). The forthcoming version of Siri is expected to utilize advanced LLMs similar to ChatGPT, Claude, and Gemini, enabling continuous conversations, human-like responses, and the completion of more complex tasks.

Apple aims to launch the LLM-powered Siri in early 2026, likely as part of an iOS 26.4 update anticipated in March. This release would occur a year later than initially planned. Additionally, by the end of next year, Apple plans to unveil a new design for Siri, potentially adopting a more humanoid appearance akin to the Mac's Finder logo.

The company has engaged in discussions with Anthropic, OpenAI, and Google, considering the use of third-party services to power the new version of Siri rather than relying solely on in-house AI models.
