Unified Text-Image Generation with Weakness-Targeted Post-Training

Jiahui Chen, Philippe Hansen-Estruch, Xiaochuang Han +7

Unified multimodal generation architectures that jointly produce text and images have recently emerged as a promising direction for text-to-image (T2I) synthesis. However, many exi…

Multimodal RewardBench 2: Evaluating Omni Reward Models for Interleaved Text and Image

Yushi Hu, Reyhane Askari-Hemmat, Melissa Hall +3

Reward models (RMs) are essential for training large language models (LLMs), but remain underexplored for omni models that handle interleaved image and text sequences. We introduce…

Text-Guided Semantic Image Encoder

Raghuveer Thirukovalluru, Xiaochuang Han, Bhuwan Dhingra +2

Image encoders, a fundamental component of vision-language models (VLMs), are typically pretrained independently before being aligned with a language model. This standard paradigm…

SEA-LION: Southeast Asian Languages in One Network

Raymond Ng, Thanh Ngan Nguyen, Yuli Huang +28

Recently, Large Language Models (LLMs) have dominated much of the artificial intelligence scene with their ability to process and generate natural languages. However, the majority…
