Secrets Within: Hiding Data in Plain Sight with AI

03.02.2026 by Ray Dalio

The system conceals information within generated text by subtly influencing the model’s token selection-specifically, ensuring each token’s assigned “bucket” aligns with a desired bit sequence derived from a hidden prompt-a process that transforms a secret message into a pattern embedded within seemingly fluent language.

Researchers have demonstrated a new method for embedding hidden information within large language models, raising concerns about model security and the potential for covert communication.

Quantization’s New Twist: Mass Diffusion for More Efficient AI

02.02.2026 by Ray Dalio

MixQuant optimizes quantization by initially reordering weights and activations to distribute activation mass evenly across blocks, then rotating these permuted tensors, and finally rounding them to a target alphabet determined by bit width, scaling, and zero point-a process designed to minimize information loss during the conversion to lower precision.

A novel framework optimizes the compression of large language models by strategically reordering data before quantization, dramatically improving accuracy and reducing computational costs.
