AvoKV-E: Payload-Aware KV Cache Eviction for Long Reasoning

Han Yu, Wenhui Zhu, Xiwen Chen et al. · 2026

Long-output reasoning shifts the KV-cache bottleneck from the fixed prompt to the generated trace. Existing reasoning-cache eviction methods largely treat cached entries as routing objects, estimating whether an old key will still be read, will recur, or can be replaced. This routing-only view overlooks two effects: lo …

Less Uniform Discrete Diffusion is More Powerful and Scalable

Kaibo Wang, Ding Ding, Fangyu Ding et al. · 2026

Although uniform diffusion language models (UDLMs) represent a promising diffusion paradigm, scaling them remains challenging. We identify the core obstacle as an over-uniform training objective and condition-target confusion during sampling. To address these, we propose Less Uniform Diffusion (LUDI), a novel UDLM fram …
