Different Tasks, Different Timesteps: Temporal Task-Aware Quantization for Diffusion Language Models

A research paper on Diffusion Language Models (DLMs) reports that quantization sensitivity in these models is both task- and time-dependent, with different downstream tasks showing distinct precision requirements across denoising steps. The work, titled "Different Tasks, Different Timesteps: Temporal Task-Aware Quantization for Diffusion Language Models," frames these findings as unique quantization challenges created by DLMs' iterative denoising process. The result points toward task-aware, timestep-specific quantization as the approach for compressing DLMs.

Diffusion Language Models DLMs introduce unique quantization challenges due to their iterative denoising process. In this work, we reveal that quantization sensitivity is both taskand time-dependent, with different downstream tasks exhibiting distinct precision requirements across denoising steps.
