Diffusion Language Models

Undergraduate research on more practical training and generation for diffusion-based language models.

Context

Diffusion language models generate text by iteratively denoising a whole sequence instead of predicting one token at a time. That opens up parallel decoding and controllable generation, but training them well and sampling from them efficiently is still an open problem.

I joined Real-Lab at GIST in March 2026 as an undergraduate research intern, advised by Prof. Kwanyoung Kim, to work on exactly that gap.

What I'm working on

  • Reproducing recent diffusion LM baselines and building a clean training and evaluation harness.
  • Studying how noise schedules and masking strategies affect sample quality and training stability.
  • Looking for ways to make generation cheaper without giving up quality.

Status

Early-stage. This page will grow as results come in; ask me about it if you're curious.
