Unified Agent targets action-ready memory across devices and time

The Unified Agent preprint proposes a compact state containing engagement evidence, stated facts and standing requests so an assistant can resume work across devices and sessions. The authors report that it outperforms adaptations of four comparator designs across multimodal models and reasoning levels. Code and data are described as forthcoming rather than confirmed available at cut-off.

Impact: cross-device continuity needs an explicit, inspectable memory contract rather than an opaque transcript. The paper does not yet establish privacy, deletion, production reliability or independent benchmark reproduction.
