Apple is rumored to open Siri to third‑party AI tools in iOS 27, expanding the assistant’s reach beyond its own Foundation Models. The move would let users tap external services through app‑based APIs, giving Siri a new layer of flexibility. This shift follows Apple Intelligence’s use of ChatGPT for complex requests in the digital ecosystem today.

Apple’s Foundation Models, slated for 2026, will still power the default Siri experience, but the new API layer could bring in Anthropic’s Claude or OpenAI’s ChatGPT. Bloomberg reports the company is negotiating with these vendors, while Google Gemini helps retrain Apple’s own models. The strategy signals Apple’s willingness to partner rather than build every layer.

Consumers will gain the ability to assign specific tasks—like coding or research—to external AI apps, while Apple keeps overall control of data flow and privacy. The default Siri will remain Apple‑owned, but the optional third‑party plug‑ins offer a broader toolkit. This approach positions iOS 27 as a more open AI platform for developers and users worldwide.
