On-Device LLMs

On-device Large Language Models (LLMs) are self-contained, privacy-preserving AI models that operate directly on your devices—smartphones, laptops, or private clouds—via the Data AI application. These models process data locally or within a secure, user-authorized environment, ensuring your data remains private and under your control.

Your on-device LLM evolves into your Personal AI by accessing data retrieved by Data Integrators and stored locally in your trusted location. By learning from your history, preferences, and behavior, it generates context-aware insights and assists with daily tasks across your applications.

Advantages of Personal AI:

• Enhanced Productivity: Streamline your digital life with AI-powered automation.

• Seamless Interaction: Engage with AI agents across the Data AI ecosystem.

• Personalized Insights: Receive recommendations and insights tailored specifically to you.

Functionality of On-Device LLMs

On-Device LLMs leverage local computational resources to perform tasks without relying on cloud-based servers. Within the Data AI ecosystem, these models are securely downloaded, stored, and managed through the Data AI application, ensuring that all data remains private and under the user's control. The operational process includes:

• Storage: Compressed models are stored on local storage devices (SSD/HDD) or within a private cloud, accessible via the Data AI app.

• Local Processing: AI computations are executed directly on the device's CPU/GPU, keeping sensitive operations confined to the local environment.

• Hybrid Model: For more complex tasks, local processing can be augmented with optional cloud resources, with the user retaining full control over data sharing.

• Local Personalization: Learning and model updates occur on-device during periods of inactivity, enabling continuous adaptation while maintaining data privacy.

Key Features of On-Device LLMs

The integration of On-Device LLMs within Data AI offers several significant benefits:

Contextual Personalization

A pivotal feature of on-device LLMs is the continuously updated Personal Index, derived from the user's daily interactions, history, and preferences. This index may encompass emails, documents, browsing patterns, purchasing habits, and other data the user opts to include. The LLM utilizes these data embeddings to generate highly personalized responses, seamlessly adapting to the user's evolving needs. Over time, the model refines these embeddings, learning unique nuances such as communication style, task priorities, and domain interests.

Hybrid Computing Architecture

While on-device LLMs handle sensitive operations locally, they can also leverage cloud-based models or specialized agents for tasks requiring more intensive computation or domain-specific expertise. For instance, the local model may process initial user queries and context retrieval, then securely transmit anonymized or restricted data to a remote agent for specialized analysis or the generation of complex outputs. The user maintains full control over when and how these external interactions occur and which data, if any, are shared.

Secure Data Handling and Trusted Execution

On-device LLMs can employ secure hardware enclaves or Trusted Execution Environments (TEEs) to further protect user data. These TEEs isolate memory and computational processes from the rest of the system, preventing unauthorized access. Combined with robust encryption and secure model-serving techniques, on-device LLMs ensure that even if an attacker gains access to the device, the user's data and embeddings remain protected.

Continuous Learning and Adaptation

With the model residing locally, it can be updated or fine-tuned iteratively as the user's preferences evolve. As Data AI users continuously retrieve data and update their Personal Indexes, the on-device model progressively improves. This incremental learning loop allows the Personal AI to refine its internal representations with minimal latency, resulting in a continuously adapting personal assistant adept at handling nuanced tasks—from scheduling and finance tracking to creative endeavors like drafting emails, documents, or creative prompts.
