Polestar targets efficient inference for diffusion language models

A new arXiv paper presents Polestar, a technique for drift-aware cache calibration and token commitment in diffusion LLM inference. The goal is to improve efficiency for language models that use diffusion-style generation.

Efficiency matters because alternative language-model architectures must compete not only on quality but also on serving cost and latency. Inference improvements can determine whether a model design is practical.

Polestar contributes to the growing body of work on making non-autoregressive or diffusion-based language models more deployable.
