Report: iOS 27 will rebuild Siri to route queries to third‑party models

Apple is remaking Siri to act as a routed assistant that can send user queries to third‑party AI models, multiple reports said this week. Bloomberg and MacRumors described the change as part of the iOS 27 engineering cycle and said tests of partner routing are under way. ### How will iOS 27 change Siri’s technical design? MacRumors reported that iOS 27 will rebuild Siri from a single-provider assistant into a router that can dispatch queries to different models depending on context and user settings. Bloomberg added that Apple’s engineering work focuses on routing logic, partner selection, and consistent fallback behavior across providers. (bloomberg.com) ### Which third‑party AI services are mentioned in reports? Bloomberg and other outlets named Google’s Gemini and Anthropic’s Claude as among the services Apple has explored integrating with Siri. (macrumors.com) MacRumors and related coverage have also described trials that pair Apple Intelligence with external models for specific tasks such as search, summarization and multi‑turn chat. (bloomberg.com) ### How would third‑party agents be delivered to iPhones? MacRumors said Apple is testing a model in which App Store‑installed agents could register as Siri partners, allowing users to choose which assistant handles particular queries. (bloomberg.com) Bloomberg’s reporting described developer‑beta experiments and App Store integration as central to the company’s plan to let external services run alongside Apple Intelligence. (macrumors.com) ### What are Apple and reporters saying about guarantees and fallback? Bloomberg reported Apple engineers are discussing consistent guarantees — for example, privacy treatments, latency classes and fallback paths — that would need to apply across multiple providers. (macrumors.com) MacRumors noted those design decisions determine the user promise Siri can make when backends differ, and that engineers are testing how Siri should behave when a partner model is unavailable. (bloomberg.com) ### How have Apple and partners responded to the reporting? Bloomberg and Reuters‑syndicated reports said Apple did not immediately respond to requests for comment when the stories first circulated in March. (bloomberg.com) Public statements from Google and Anthropic cited in press coverage have said only that they continue to work with platform partners on a range of integrations; none confirmed specific routing contracts with Apple in the reporting. (macrumors.com) ### When will details be revealed to the public? Apple is scheduled to unveil iOS 27 at its Worldwide Developers Conference keynote on June 8, 2026, where reporters expect the company to present the rebuilt Siri, developer tools and details about partnering and routing. (finance.yahoo.com) Apple’s announced WWDC date and multiple outlets’ reporting set the next milestone for the feature; developers and partners will be watching the company’s technical and contractual descriptions at the June 8 presentation.
