DiffuMamba: High-Throughput Diffusion LMs with Mamba Backbone

arXiv:2511. 15927v4 Announce Type: replace-cross Abstract: Diffusion language models (DLMs) have emerged as a promising alternative to autoregressive (AR) generation, yet their reliance on Transformer backbones limits inference efficiency due to quadratic attention or KV-cache overhead.

Rethinking User Encoders: Routing Diffusion States for Scenario-Adaptive User Representation

The paper introduces FINDERS, a diffusion‑language‑model framework that replaces static user encoders with a dynamic routing system. FINDERS uses four operations—denoise, factorize, route, and compress—to create scenario‑adaptive user representations by organizing denoising states into transferable cross‑modal semantics and modality‑specific factors. The authors also build BehaviorQA, a large corpus with explicit behavioral rationales, and demonstrate through extensive experiments and online A/B tests that FINDERS outperforms existing methods across ten industrial scenarios.

Predict, Don't Iterate: Efficient Adaptive-Length Infilling for Diffusion Language Models

The paper introduces PILL, a new infilling technique for diffusion language models that eliminates the need for a preset initial length and reduces inference overhead. PILL uses probing-based length-free decoding, cutting down on extra forward passes and speeding up generation. Experiments across five diffusion models and eight benchmarks show PILL outperforms the strongest baseline with higher pass rates and BLEU-2 scores while running 1.82× faster.
