LLaDA-Rec: Discrete Diffusion for Parallel Semantic ID Generation in Generative Recommendation

Teng Shi, Chenglei Shen, Weijie Yu +6

Generative recommendation represents each item as a semantic ID, i.e., a sequence of discrete tokens, and generates the next item through autoregressive decoding. While effective,…

UltraLLaDA: Scaling the Context Length to 128K for Diffusion Large Language Models

Guangxin He, Shen Nie, Fengqi Zhu +6

Diffusion LLMs have attracted growing interest, with plenty of recent work emphasizing their great potential in various downstream tasks; yet the long-context behavior of diffusion…

LLaDA-V: Large Language Diffusion Models with Visual Instruction Tuning

Zebin You, Shen Nie, Xiaolu Zhang +5

In this work, we introduce LLaDA-V, a purely diffusion-based Multimodal Large Language Model (MLLM) that integrates visual instruction tuning with masked diffusion models, represen…

LLaDA 1.5: Variance-Reduced Preference Optimization for Large Language Diffusion Models

Fengqi Zhu, Rongzhen Wang, Shen Nie +8

While Masked Diffusion Models (MDMs), such as LLaDA, present a promising paradigm for language modeling, there has been relatively little effort in aligning these models with human…

Large Language Diffusion Models

Shen Nie, Fengqi Zhu, Zebin You +7

The capabilities of large language models (LLMs) are widely regarded as relying on autoregressive models (ARMs). We challenge this notion by introducing LLaDA, a diffusion model tr…

Real-time Identity Defenses against Malicious Personalization of Diffusion Models

Hanzhong Guo, Shen Nie, Chao Du +3

Personalized generative diffusion models, capable of synthesizing highly realistic images based on a few reference portraits, may pose substantial social, ethical, and legal risks…
