MetaState: Persistent Working Memory Enhances Reasoning in Discrete Diffusion Language Models

Kejing Xia, Mingzhe Li, Lixuan Wei +5

Discrete diffusion language models (dLLMs) generate text by iteratively denoising a masked sequence. However, standard dLLMs condition each denoising step solely on the current har…

CopT: Contrastive On-Policy Thinking with Continuous Spaces for General and Agentic Reasoning

Dachuan Shi, Hanlin Zhu, Xiangchi Yuan +4

Chain-of-thought (CoT) is a standard approach for eliciting reasoning capabilities from large language models (LLMs). However, the common CoT paradigm treats thinking as a prerequi…
