Apple's Siri AI Can Be Swapped Out for Claude, ChatGPT, Code Shows (www.macrumors.com)

Recent code discoveries indicate that Apple has revamped its Siri architecture to integrate third-party AI models like Claude and ChatGPT. A newly revealed mechanism called Model Delegation allows users to select Claude as an extension within Siri, enabling complex tasks like setting reminders through natural language requests. When Claude encounters functionality beyond its capabilities, such as creating a CSV file, it defers to Siri, showcasing a collaborative dynamic between the two models. Significantly, a protocol called Inference Provider within Apple's Model Manager Services could enable complete model replacement, allowing advanced models like GPT-5.6 to effectively take over Siri’s functionalities. This empowers users to conduct sophisticated queries, such as summarizing emails or sending messages, directly via the Siri interface. The move may be influenced by the European Union's Digital Markets Act, which mandates third-party access to Apple services, suggesting Apple is preparing for a more open AI ecosystem. While the current functionalities are limited to the ChatGPT extension in the upcoming macOS updates, these developments hint at a future where Siri's capabilities could be greatly expanded through third-party integrations.
