DeepEyes: Incentivizing "Thinking with Images" via Reinforcement Learning

ICLR 2026poster

Large Vision-Language Models excel at multimodal understanding but struggle to deeply integrate visual information into their predominantly text-based reasoning processes, a key challenge in mirroring human cognition. To address this, we introduce DeepEyes, a model that learns to ``think with images…

DeepEyesV2: Toward Agentic Multimodal Model

ICLR 2026poster

Agentic multimodal models should not only comprehend text and images, but also actively invoke external tools, such as code execution environments and web search, and integrate these operations into reasoning. In this work, we introduce DeepEyesV2 and explore how to build an agentic multimodal model…

Cheems: A Practical Guidance for Building and Evaluating Chinese Reward Models from Scratch

ACL 2025long

Reward models (RMs) are crucial for aligning large language models (LLMs) with human preferences. However, most RM research is centered on English and relies heavily on synthetic resources, which leads to limited and less reliable datasets and benchmarks for Chinese. To address this gap, we introduc…

Distinguish Before Answer: Generating Contrastive Explanation as Knowledge for Commonsense Question Answering

ACL 2023findings

Existing knowledge-enhanced methods have achieved remarkable results in certain Q&A tasks via obtaining diverse knowledge from different knowledge bases. However, limited by the properties of retrieved knowledge, they still have trouble benefiting from both the knowledge relevance and distinguishmen…

HiTeA: Hierarchical Temporal-Aware Video-Language Pre-training

ICCV 2023poster

Video-language pre-training has advanced the performance of various downstream video-language tasks. However, most previous methods directly inherit or adapt typical image-language pre-training paradigms to video-language pre-training, thus not fully exploiting the unique characteristic of video, i.…

UReader: Universal OCR-free Visually-situated Language Understanding with Multimodal Large Language Model

EMNLP 2023long findings

Text is ubiquitous in our visual world, conveying crucial information, such as in documents, websites, and everyday photographs. In this work, we propose UReader, a first exploration of universal OCR-free visually-situated language understanding based on the Multimodal Large Language Model (MLLM). B…

mPLUG-2: A Modularized Multi-modal Foundation Model Across Text, Image and Video

ICML 2023poster

Recent years have witnessed a big convergence of language, vision, and multi-modal pretraining. In this work, we present mPLUG-2, a new unified paradigm with modularized design for multi-modal pretraining, which can benefit from modality collaboration while addressing the problem of modality entangl…

DictBERT: Dictionary Description Knowledge Enhanced Language Model Pre-training via Contrastive Learning

IJCAI 2022poster

Although pre-trained language models (PLMs) have achieved state-of-the-art performance on various natural language processing (NLP) tasks, they are shown to be lacking in knowledge when dealing with knowledge driven tasks. Despite the many efforts made for injecting knowledge into PLMs, this problem…
