Text Template Tokens Are Implicit Semantic Registers in Diffusion Transformers

Maohua Li, Qirui Li, Yanke Zhou +10

Modern text-to-image diffusion transformers (DiTs) generate images through joint attention, in which text and image tokens interact directly within a single sequence. In large-scal…

Compressed Sensing for Capability Localization in Large Language Models

Anna Bair, Yixuan Even Xu, Mingjie Sun +1

Large language models (LLMs) exhibit a wide range of capabilities, including mathematical reasoning, code generation, and linguistic behaviors. We show that Transformer architectur…

Rethinking Cross-Layer Information Routing in Diffusion Transformers

Chao Xu, Maohua Li, Qirui Li +9

Diffusion Transformers (DiTs) have become a de facto backbone of modern visual generation, and nearly every major axis of their design -- tokenization, attention, conditioning, obj…

Linear-DPO: Linear Direct Preference Optimization for Diffusion and Flow-Matching Generative Models

Kesong Li, Yixuan Xu, Kuo-kun Tseng +3

Direct Preference Optimization (DPO) is successful for alignment in LLMs but still faces challenges in text-to-image generation. Existing studies are confined to denoising diffusio…

Apertus: Democratizing Open and Compliant LLMs for Global Language Environments

Project Apertus, Alejandro Hernández-Cano, Alexander Hägele +100

We present Apertus, a fully open suite of large language models (LLMs) designed to address two systemic shortcomings in today's open model ecosystem: data compliance and multilingu…

P/D-Device: Disaggregated Large Language Model between Cloud and Devices

Yibo Jin, Yixu Xu, Yue Chen +27

Serving disaggregated large language models has been widely adopted in industrial practice for enhanced performance. However, too many tokens generated in decoding phase, i.e., occ…
