In March 2026, Apple unveiled the most significant upgrade to Siri in its history, powered by Google Gemini as its core AI engine, delivered through the iOS 26.4 update. This is not a minor improvement — it is a fundamental transformation of Siri from a basic voice assistant into a context-aware AI Assistant capable of multi-step tasks and seamless cross-app integration. This article analyzes how the deal came about, what the new features are, and what it means for users and businesses alike.
The Big News: Apple x Google — A Billion-Dollar Deal
Apple has agreed to pay Google approximately $1 billion per year to use Gemini as Siri's primary AI engine. This deal is significant on multiple levels:
- Apple acknowledged its own AI was not sufficient — after years of in-house AI development, Apple decided that partnering with Google would be faster and more effective
- Google gains access to over a billion iPhone users — Gemini will be embedded in every Apple device that updates to iOS 26.4
- The deal mirrors the Search Engine agreement — Apple previously received payments from Google to remain the default search engine on Safari, a deal worth over $20 billion per year
Why not ChatGPT?
Earlier reports suggested Apple was in negotiations with OpenAI to bring ChatGPT to Siri. Ultimately, Apple chose Gemini because Google had a significant advantage in integration with services that many iPhone users already rely on — Gmail, Google Maps, and YouTube — along with strong multimodal processing capabilities.
Exciting New Features
The Gemini-powered Siri comes with several new capabilities that fundamentally change how people use their smartphones:
1. On-Screen Awareness — Understanding What's on Your Screen
The most compelling feature is On-Screen Awareness — Siri can now "see" and "understand" what is currently displayed on your iPhone screen. For example:
- Browsing a restaurant website, you say "Book a table here tonight" — Siri extracts the restaurant details from the screen and makes the reservation
- Receiving a flight confirmation email, you say "Add this flight to my calendar" — Siri pulls the flight information from Mail and creates a Calendar event
- Viewing a photo, you say "Send this to Mom" — Siri sends the photo you're looking at via Messages
2. Multi-Step Task Execution
The new Siri doesn't just answer questions — it can execute multi-step workflows from a single command:
- "Find a Japanese restaurant near work, book a table for 4 on Friday, and send the details to my team" — Siri searches, books, and shares information in one go
- "Look up flights to Chiang Mai next week, compare prices, and send the options to my wife" — Siri aggregates data from multiple sources and sends a summary
3. Cross-App Integration
What makes the new Siri dramatically different from previous versions is its ability to work seamlessly across multiple apps:
- Extract flight information from Mail, share details via Messages, and add it to Calendar
- Read reservation data from Notes, create a reminder in Reminders, and share the location via Maps
- Pull images from Photos, edit text in Pages, and send an email via Mail
4. Conversational AI — Continuous Context
The new Siri can remember conversation context. You can carry on a natural conversation without restarting your command each time:
- "What's the weather today?" followed by "What about tomorrow?" followed by "Should I bring an umbrella if it rains?" — Siri understands the context throughout the entire conversation
| Feature | Old Siri | Siri + Gemini |
|---|---|---|
| Screen Understanding | Not available | On-Screen Awareness |
| Multi-Step Tasks | Very limited | Full Multi-Step Execution |
| Cross-App | Select apps only | All apps supported |
| Context Memory | Not available | Continuous conversation |
| AI Engine | Apple ML | Google Gemini |
Privacy: Apple Private Cloud Compute
One of the primary concerns when Apple partners with Google is privacy. Apple addresses this with its Private Cloud Compute (PCC) technology:
How Apple Private Cloud Compute Works
- On-device processing first — simple commands are processed directly on your iPhone/iPad, with no data leaving the device
- End-to-end encryption — when cloud processing is needed, data is encrypted before transmission and decrypted only on your device
- No data retention on cloud — data is deleted from servers immediately after processing is complete
- Google never sees raw data — Gemini receives only filtered "queries," not your full personal information
This approach differs fundamentally from using ChatGPT or Gemini directly, where data is sent to the provider's servers. By placing PCC as an intermediary layer, Apple allows users to benefit from advanced AI without sacrificing privacy.
A Delayed Journey: From 2025 to 2026
Apple originally announced AI features for Siri at WWDC 2024, with an expected launch in 2025. However, the timeline slipped multiple times:
- Mid-2025 — Apple acknowledged that "Apple Intelligence" was not ready; several features were delayed
- Late 2025 — Reports emerged that Apple was in negotiations with Google about Gemini
- January 2026 — Apple and Google officially signed the agreement
- March 2026 — Siri + Gemini launched via iOS 26.4
This delay illustrates that developing production-ready AI is extraordinarily difficult. Even a company like Apple, with virtually unlimited resources, ultimately concluded it needed an external AI partner.
Apple's decision to use Gemini rather than building from scratch sends a clear signal: foundational AI models require specialized investment and expertise at a scale that makes partnerships more practical than going it alone — even for the world's most valuable company.

Impact on Enterprise Users
For businesses and organizations, the Gemini-powered Siri will change several aspects of how work gets done:
Benefits for Businesses
- Increased productivity — employees can issue more complex voice commands, reducing time spent switching between apps
- Cross-app data management — extract data from email, schedule meetings, and share documents in a single command
- Improved multilingual support — Gemini's language capabilities are significantly better than the old Siri, including for Thai language users
Concerns for Businesses
- Corporate data privacy — even with PCC, organizations should review their data security policies when employees use Siri with sensitive information
- Vendor dependency — Siri now depends on both Apple and Google; if Gemini experiences issues, Siri will be affected too
- Upgrade costs — older devices may not support iOS 26.4, requiring organizations to plan device upgrade cycles
In an era where AI plays an increasingly central role, it is essential for organizations to maintain robust authentication systems and reliable digital signatures to prevent unauthorized access to data through AI channels.
Impact on Thai Users
For iPhone users in Thailand, this change has several noteworthy implications:
| Aspect | Impact |
|---|---|
| Thai Language | Gemini's Thai language capabilities are significantly better than old Siri, enabling smoother Thai voice commands |
| Local Services | Cross-app integration may initially be limited with Thai-specific apps like LINE and banking apps |
| Device Compatibility | Requires iPhone 15 Pro or later, or any iPhone 16, for full feature support |
| Thai Developers | New opportunities to build apps that leverage Siri Intents with the Gemini API |
Timeline and Availability
- March 2026 — iOS 26.4 launches with Siri + Gemini in the United States
- April 2026 — Expansion to English-speaking countries (UK, Australia, Canada)
- Q2-Q3 2026 — Additional language support, expected to include Thai
- WWDC 2026 (June 2026) — Apple expected to unveil additional Siri + Gemini capabilities
Conclusion: A New Era for AI Assistants
The Apple x Google Gemini deal for Siri marks a pivotal moment in the AI industry:
- It demonstrates that even the largest tech companies must collaborate in the AI era
- It raises the bar for smartphone AI assistants by a significant margin
- It creates competitive pressure for Samsung, Google (for Pixel), and other manufacturers to accelerate their own AI development
- It opens new opportunities for developers and businesses looking to leverage AI in their workflows
For organizations in Thailand and across Asia, the key takeaway is to prepare for this transformation — by updating devices, reviewing security policies, and identifying opportunities to use AI to improve productivity. At the same time, it is important to recognize that AI is a tool that enhances human capability, not a replacement for it.
