On September 28th, according to Bloomberg yesterdayappleA similar one is being developed ChatGPT A mobile application to help test and prepare for the upcoming release next year Siri.

It was reported that Apple ' s artificial intelligence department was using the application ' s new rapid assessment of Siri ' s new functionality, which included testing for personal data search, and carrying out inside-App operations (e.g. editing photographs)。
The software is code-named "Veritas" ("Truth" in Latin)Currently available for in-house use only。Although the software was not intended to be consumer-oriented, the App function was essentially to extract new technologies being developed from the new Siri, thus helping apple workers to complete the test efficiently。
It was noted that, even in the absence of a public release, this internal tool marked a new stage in the preparation of apples for the full upgrade of Siri。IT WAS REPORTED THAT THIS WAS A HIGH-RISK RELEASE AND THAT THERE WAS A RISK OF RECASTING APPLE AI EFFORTS。
The news also revealed that:The new Siri has experienced several rounds of delays and is now scheduled to be launched next March。If the new Siri could do what Apple promised to do at the time, it would help the apple to re-engage in artificial intelligence。
The bottom of Veritas' run is known to be apple-driven new Siri and the new system, codenamed "Linwood". At the same time, Veritas relies on the Big Language Model (LLM) and combines the work of the Apple's own basic model team。
In addition, according to a 9to5Mac report earlier, hidden codes from iOS 26.1, iPados 26.1 and macos Tahoe 26.1 developed versions show that apples are laying the groundwork for the introduction of MCP support for AppIntents。
This also means that in the future, we can allow ChatGPT, Claude or any other MCP compatible AI model to interact directly with Mac, iPhone and iPad applications。
According to the analysis of iOS 26.1 and other test software codes, apples do not allow each application to support MCP alone. On the contrary, it is building a system-level MCP support that is directly integrated in the App Intens framework。
This means that on the iPhone, Siri/AppleInteligence (driven by the Apple Foundation Model) understands your request and can trigger AppIntents to perform local actions; when the system judges that a wider knowledge is needed, the necessary content is given to ChatGPT to get answers。
