A new research paper introduces $\pi$-RAG, a novel architecture designed to enhance privacy in retrieval-augmented generation (RAG) systems for large language models (LLMs). This approach decouples LLMs from sensitive data by using the digits of $\pi$ as an immutable indirection layer, preventing direct access to private records and mitigating inversion attacks. The system incorporates a Semantic Quantization Layer that maps user inputs to deterministic offsets, generating a $\pi$-key which then points to the relevant data payload. This method aims to provide deterministic randomness, auditability, and differential privacy, making it suitable for high-compliance industries like finance and healthcare. AI
