Apple does not associate its intelligence capabilities with users' Apple IDs and does not train its core models using data from users' devices, whether on-device or in private cloud settings. Apple Intelligence primarily functions on-device, with many operations and features driven by models running directly on your iPhone or iPad. If a request requires more computational power, it extends to private cloud computing to handle the query.

The diagram above illustrates how Apple Intelligence utilizes on-device processing and private cloud computing. Orchestration determines which data needs to be sent to private cloud computing according to the requirements.


Let's delve deeper into On-Device Processing and Private Cloud Computing.


On-Device Processing: On-device processing enables devices such as smartphones, tablets, and wearables to execute tasks and handle data locally, without relying on external servers or cloud systems. This is a crucial aspect of many Apple technologies, especially within Apple Intelligence, where privacy, speed, and efficiency are emphasized. Apple Intelligence uses Local Models & Personalization to employ compact and efficient local models, allowing them to function directly on the user's device. These models are optimized for tasks like text prediction, autocorrect, and basic language understanding. Personalization models adapt by analyzing user behavior and preferences to customize suggestions and recommendations to suit user needs.


Benefits of On-Device Processing


  • Privacy and Security: Handling data locally ensures that sensitive information remains on the device, improving user privacy as the data does not leave the device. On-device processes are encrypted to enhance security.

  • Faster Performance: On-device data processing provides instant results, eliminating the need for cloud upload and download. Tasks like voice recognition, image processing, and AI features benefit from reduced latency, offering quicker user responses.

  • Reduced Dependence on Internet Connectivity: On-device processing enables features like Siri voice recognition and Maps navigation to function without an internet connection, enhancing usability in areas with poor connectivity. It also conserves internet bandwidth by eliminating the need to send large data to external servers.

  • Power Efficiency: Apple's A-series processors and Neural Engine are optimized for on-device AI and machine learning, performing complex tasks efficiently and extending battery life by consuming less power.


Examples of On-Device Processing


  • Siri: Processes voice commands locally to provide quicker, more private responses, managing tasks such as setting timers or adjusting device settings.

  • Face ID: The recognition data is securely handled on the device with the A-series chip and Neural Engine, ensuring it is not uploaded to external servers.

  • Photo and Video Processing: Features like Smart HDR, Deep Fusion, and Night Mode use on-device machine learning for real-time photo and video optimization.

  • Health and Fitness Tracking: Apple Watch processes health metrics such as heart rate, steps, ECG, and blood oxygen levels on-device.

  • Keyboard and Text Prediction: On-device processing is used for predictive text, autocorrections, and suggestions, keeping user data private.

  • Apple Maps: Route planning and traffic updates increasingly rely on on-device processing for more immediate navigation.


Private Cloud Computing (PCC): Apple's Private Cloud Compute (PCC) is a cloud infrastructure engineered to securely and privately manage user's data, particularly for complex tasks requiring substantial computational power. Its primary focus is enhancing the security and privacy of Apple devices in the cloud, ensuring that only users have access to their data, not Apple. PCC operates on Apple's silicon and a highly secure, privacy-focused operating system, making it ideal for large-scale cloud AI operations.


It employs stateless computing, meaning user data is utilized solely to fulfill requests and is not retained thereafter. PCC ensures that its security and privacy features are inherently integrated and do not rely on external elements. It prohibits any special access, ensuring that even in the event of significant issues, Apple personnel cannot circumvent privacy protections. PCC ensures that targeting specific users' data would require compromising the entire system. It also provides transparency, allowing security experts to evaluate its security and privacy measures through publicly available software versions. User data is encrypted before transmission to the cloud and is deleted immediately after the request is completed, ensuring it is never stored on Apple's servers.


Architectural Principles


  • Stateless Computation: Data is processed without storage, ensuring no trace remains.

  • Enforceable Guarantees: Security and privacy protocols are technically enforced.

  • No Privileged Access: Restricting access to essential system components.

  • Non-Targetability: Making it difficult for attackers to target specific users.

  • Verifiable Transparency: Allowing security researchers to verify the system's security and privacy claims.


How PCC Manages User Data


  1. A user's device sends data to PCC solely to execute the user's inference request. PCC uses the data only to perform the requested operations.

  2. PCC deletes the user's data once the request is completed, ensuring no user data is retained in any form after the response is delivered.

  3. Apple does not have access to user data, even for employees with administrative access to the production service or hardware.


Apple Intelligence's Private Cloud Compute creates a secure request containing the prompt, model, and inference parameters. The user's device encrypts this request and sends it to authorized certified PCC nodes. Since PCC lacks storage capabilities, it cannot retain data after processing requests. Administrators cannot remotely access the servers. The specialized hardware only provides performance metrics for administrative purposes. A robust cryptographic and attestation process secures the communication and prevents any targeting of specific servers.


The diagram depicts a secure and transparent setup for Private Cloud Compute (PCC), likely within Apple's ecosystem due to the inclusion of an "Apple silicon server." Users engage through a PCC Client, sending prompts to different versions of the private cloud. These prompts, along with the generated responses and cryptographic attestations confirming the integrity of the computations, are recorded in a public transparency log. This logging focus ensures auditability and accountability. The PCC environment consists of an ML stack for machine learning tasks, private cloud extensions for customization, and a private cloud compute OS, all operating on Apple's silicon. This configuration indicates an emphasis on verifiable, auditable, and potentially sensitive computations within a controlled environment.
