Siri AI Overhaul: Project Campos & 12GB RAM

Key Takeaways

• LLM Brain Transplant: Apple is transitioning Siri to an LLM-based system powered by Google’s Gemini and Apple Foundation Models v11.
• On-Screen Awareness: Siri will soon ‘see’ and understand your current screen context, enabling cross-app actions like “Send this to Mom.”
• The 12GB RAM Wall: Full on-device AI features require a minimum of 12GB of RAM, making older 8GB devices partially obsolete.
• Private Cloud Compute (PCC): Apple’s PCC handles complex requests with end-to-end encryption and stateless processing for maximum privacy.

Introduction: Siri and the Sovereign Era in 2026

Direct Answer: What is the ‘Project Campos’ Siri overhaul?
Project Campos is the code name for Apple’s complete architectural overhaul of Siri in 2026, transitioning it from a rigid intent-based engine to a modern, Large Language Model (LLM)-based system. Powered by a partnership with Google’s Gemini and the next-gen Apple Foundation Models (AFM) v11, the new Siri features “On-Screen Awareness” and “Personal Context” indexing. However, this “brain transplant” comes with steep hardware requirements, requiring at least 12GB of RAM for full local functionality. To maintain Data Sovereignty, Apple utilizes Private Cloud Compute (PCC) on Apple Silicon servers, ensuring that even cloud-assisted requests remain encrypted and stateless, protecting user privacy in a way that traditional cloud AI cannot.

“Siri is no longer just a voice assistant; it is becoming your primary autonomous agent, deeply integrated into the fabric of iOS.”

Benchmarking the efficiency and sovereignty of Siri’s new architecture.

Feature / Option	Sovereignty Status	Data Locality	Security Tier	Score
Legacy Siri	🔴 Low (Intent-Only)	🟡 50% (Cloud)	🟡 Standard	2/10
Siri Lite (8GB)	🟡 Medium (Hybrid)	🟡 30% (Edge)	🟢 High (PCC)	6/10
Siri Pro (12GB+)	🟢 Full (Local)	🟢 90% (Physical)	🟢 Elite (PQC)	9/10

The Core Technology: Project Campos Architecture

The core of the Siri overhaul is the Reasoning Router, a multi-model triage system that decides where to process your request:

1. Local Triage (AFM-Lite): Handles basic tasks (alarms, timers) on-device with zero latency.
2. On-Device Reasoning (AFM-v11): Processes “On-Screen Awareness” and “Personal Context” using local NPU cycles.
3. Cloud Hand-off (Gemini/PCC): Routes complex “World Knowledge” queries to encrypted Apple Silicon servers.

Technical Nuance: The 12GB RAM Wall

Why does the new Siri require so much memory? A 10B parameter model, even with 4-bit quantization, requires roughly 5GB to 6GB of RAM just to stay resident. When combined with the Vision-Language Model for on-screen awareness and the OS overhead, 8GB devices (like the iPhone 15/16 Pro) are forced into “Siri Lite” mode, offloading more data to the cloud.

The “Sovereign” Perspective

Apple’s approach to AI sovereignty rests on Private Cloud Compute (PCC). Unlike traditional cloud AI, PCC nodes are stateless and verifiable. Your personal context—emails, messages, and photos—is indexed locally. When a request requires more power than your iPhone can provide, only the necessary snippets are sent to PCC, encrypted with a key that even Apple cannot access. This ensures that your Personal Knowledge Graph remains your property, not a training data point for a central model.

Actionable Steps: Preparing for Siri 2.0

1. Audit Your Hardware: Check if your device has at least 12GB of RAM to support the full local Siri experience.
2. Update to iOS 26.4: Ensure you are on the latest firmware to receive the Project Campos updates.
3. Review App Permissions: Siri’s new “On-Screen Awareness” requires permission to read app data; audit these in Settings > Siri & Search.
4. Adopt App Intent 3.0: For developers, mapping your app’s functions to the new API is mandatory for Siri compatibility.

Part 1: Code for the Siri Implementation (Swift)

In 2026, we don’t trust our settings; we audit them. This Swift snippet allows you to verify your Data Sovereignty or automate a local-first workflow for App Intent 3.0.

import AppIntents

struct SendPhotoIntent: AppIntent {
  static var title: LocalizedStringResource = "Send Photo via Siri"
  
  @Parameter(title: "Recipient")
  var recipient: String
  
  @Parameter(title: "Photo")
  var photo: PhotoEntity
  
  func perform() async throws -> some IntentResult {
    // Logic to send the photo locally without cloud intermediate
    let success = try await LocalPhotoManager.shared.send(photo, to: recipient)
    
    if success {
        return .result(dialog: "Sent the photo to \(recipient) securely.")
    } else {
        throw IntentError.failedToSend
    }
  }
}

ASO and GEO for the Siri Ecosystem

ASO (App Store Optimization) for Siri-Aware Apps

In 2026, apps that are “Siri-Native” rank higher in the App Store.

1. Intent Integration: Highlight “Full Siri Support” and “App Intent 3.0 Compatible” in your app description.
2. Privacy Badging: Use terms like “On-Device AI” and “PCC-Encrypted” to appeal to privacy-conscious users.

GEO (Generative Engine Optimization) for Siri Search

Siri’s personalized search results are the new “Front Page” of the internet.

1. Structured Entities: Use Schema.org markup to define your business entities so Siri’s personal context engine can index them correctly.
2. Authority Signals: Verified business listings and PGP-signed reviews are prioritized by Siri’s reasoning engine.

Frequently Asked Questions (FAQ)

Will my iPhone 16 Pro support the new Siri?

It will support “Siri Lite.” Because the iPhone 16 Pro only has 8GB of RAM, it cannot run the full on-device models required for local on-screen awareness and must offload more tasks to PCC.

Is my data shared with Google?

Requests that require “World Knowledge” are sent to Google’s Gemini models, but they are stripped of personal identifiers by Apple’s Reasoning Router and processed through PCC.

Can I turn off On-Screen Awareness?

Yes. You can disable Siri’s ability to “see” your screen in the Siri & Search settings menu, though this will limit its ability to perform cross-app actions.

The Verdict: The Future is Agentic

Siri’s 2026 overhaul is more than just a software update; it’s a fundamental shift in how we interact with technology. By balancing massive AI power with a strict adherence to Data Sovereignty, Apple is defining the standard for the next generation of personal computing.
