Two tutorial posts on Hacker News today trace the two distinct technical lineages of diffusion language models — discrete masked and continuous embedding-space — both of which have now reached production deployments with 2–10× throughput gains over autoregressive models. The quality gap with AR is measurably narrowing.

The reformulation unifies 20+ recent papers under three consistency constraints and explains why single-step sampling is achievable without sacrificing bijectivity.
