Apple just shipped the biggest Siri update in 13 years with iOS 26.4. Powered by Google's 1.2 trillion parameter Gemini model and running on Apple's Private Cloud Compute infrastructure, the new Siri is not just a voice assistant that sets timers and plays music. It is a genuine AI agent that can see your screen, chain actions across multiple apps, and remember your conversations.
This is the update that iPhone users have been waiting for since ChatGPT made the old Siri look embarrassingly outdated. Here is everything that changed, how it compares to ChatGPT and Google Assistant, and what it means for the future of AI on your phone.
What Changed: The Four Big Upgrades

1. On-Screen Awareness
Old Siri was blind — it could not see what was on your screen. New Siri can analyze everything currently displayed and take contextual action. Looking at a restaurant in Safari? Say "book a table here for Friday." Siri reads the restaurant name, finds booking options, and handles the reservation. Reading an article? Say "summarize this page" and Siri processes the visible content instantly.
2. Cross-App Actions
This is the game-changer. You can now give Siri multi-step instructions that span different apps. "Take the photo I just shot, make it brighter, add a warm filter, and send it to Mom with the message 'from yesterday's hike.'" Siri chains actions across Camera Roll, Photos editing, and Messages seamlessly. Previous Siri could only handle single-app commands.
3. Conversational Memory
Old Siri treated every request as isolated — no memory of what you discussed 5 minutes ago, let alone yesterday. The new Siri maintains conversation context across sessions. Ask about a flight you discussed yesterday, and it remembers the airline, time, and destination without you repeating a single detail. This persistent memory transforms Siri from a command tool into an actual assistant.
4. Gemini-Powered Reasoning
Complex questions that old Siri would punt to a web search now get detailed, accurate, nuanced responses. "Compare the pros and cons of moving to Austin versus Denver for a remote tech worker" — old Siri would open Safari. New Siri gives you a structured comparison with cost of living, weather, tech scene, and tax implications. The Gemini model's reasoning capability is a generational leap.
The Apple-Google Partnership: Why It Matters

Generated with AI by Tech4SSD
This partnership is the most significant deal in tech since Apple put Google Search on the original iPhone. Apple gets world-class AI without spending years building their own frontier model. Google gets distribution to over 1 billion active iPhones — instantly becoming the AI backbone for the most premium user base in the world.
The financial terms have not been disclosed, but analysts estimate Google is paying Apple between $15-20 billion annually for the integration — similar to the Google Search deal but potentially larger given the strategic value of AI distribution.
Privacy Deep Dive: Apple processes all Siri requests through Private Cloud Compute (PCC). Your data is encrypted end-to-end, processed in isolated secure enclaves, and Apple states that even their own engineers cannot access it. Google receives anonymized, stripped-down queries only — no user identity, location history, or personal data crosses to Google's servers. Independent security audits of PCC have confirmed these claims.

Old Siri vs New Siri: Complete Comparison
How It Compares to ChatGPT and Google Assistant
How to Get It
The new Siri rolls out with iOS 26.4, expected in late March 2026. To get it:
- Go to Settings → General → Software Update
- Download and install iOS 26.4
- Siri upgrades automatically — no additional setup required
- For best results, enable "On-Screen Awareness" in Settings → Siri → Advanced
Compatible Devices: iPhone 15 and later for full Gemini-powered features. iPhone 13/14 get some improvements but without on-screen awareness or cross-app chaining.
After 13 years of incremental updates and increasingly embarrassing comparisons to ChatGPT, Apple finally delivered a Siri worth using. The combination of Gemini's intelligence and Apple's ecosystem integration creates something neither company could have built alone — a private, capable, and genuinely helpful AI agent that lives on the device you already carry everywhere.
