Apple is preparing to offer iPhone users a brand-new experience with iOS 27. Siri, which has been a closed system for years, is finally opening its doors to third-party AI assistants. According to a recent report by Bloomberg, users will be able to choose which AI responds to their voice commands. This major step means the iPhone will no longer be dependent solely on Apple’s own AI or just ChatGPT.
Siri Goes Open: Apple Frees AI Assistants with iOS 27
Thanks to the “Extensions” system Apple is developing, chatbots available on the App Store can be integrated into Siri. With this new system, Google Gemini, Anthropic Claude, and other AI models will work in direct harmony with the iPhone’s voice assistant. Currently, Siri acts more like a middleman, only routing complex questions to ChatGPT. The new report states that this change is a completely separate move from Apple’s ongoing efforts to rebuild Siri’s core infrastructure using Gemini models.

This development holds a massive opportunity, particularly for Google Gemini. Google aims to turn Gemini into a true assistant, not just a chatbot, by introducing it across all platforms. If Apple permits this deep integration, Gemini’s real-time web context and multimodal understanding capabilities will come directly to iPhone devices.
Privacy and the Future of the Ecosystem
Until now, Apple followed a cautious strategy prioritizing privacy and on-device processing. While great for security, this slowed Siri’s growth. However, the company has decided to delegate complex tasks to other AI giants rather than trying to do everything itself. Adding Gemini, which is deeply connected to daily Google services, will rapidly increase the iPhone’s capabilities without Apple needing to rebuild every feature from scratch.
Several questions remain regarding this process. It is currently unclear how Apple will protect user privacy while data is sent to Google servers. Additionally, the revenue-sharing model for premium AI subscriptions sold through Siri and how seamlessly these external models will blend with Apple’s native systems are major points of interest. All these details are expected to become clear when iOS 27 is unveiled at the WWDC 2026 event in June.
By stretching its long-standing closed ecosystem and opening Siri to rival AI models, Apple could drastically change our smartphone habits.
