We further make three key contributions for VisIR. First, we create **VIRA** (Vis-IR Aggregation), a large-scale dataset comprising a vast collection of screenshots from diverse sources, carefully curated into captioned and questionanswer formats. Second, we develop **UniSE** (Universal Screenshot Embeddings), a family of retrieval models that enable screenshots to query or be queried across arbitrary data modalities. Finally, we construct **MVRB** (Massive Visualized IR Benchmark), a comprehensive benchmark covering a variety of task forms and application scenarios. Through extensive evaluations on MVRB, we highlight the deficiency from existing multimodal retrievers and the substantial improvements made by UniSE. ## Model Usage > Our code works well on transformers==4.45.2, and we recommend using this version. ### 1. UniSE-MLLM Models ```python import torch from transformers import AutoModel MODEL_NAME = "marsh123/UniSE-MLLM" model = AutoModel.from_pretrained(MODEL_NAME, trust_remote_code=True) # You must set trust_remote_code=True model.set_processor(MODEL_NAME) with torch.no_grad(): device = torch.device("cuda:0") model = model.to(device) model.eval() query_inputs = model.data_process( images=["./assets/query_1.png", "./assets/query_2.png"], text=["After a 17% drop, what is Nvidia's closing stock price?", "I would like to see a detailed and intuitive performance comparison between the two models."], q_or_c="query", task_instruction="Represent the given image with the given query." ) candidate_inputs = model.data_process( images=["./assets/positive_1.jpeg", "./assets/neg_1.jpeg", "./assets/positive_2.jpeg", "./assets/neg_2.jpeg"], q_or_c="candidate" ) query_embeddings = model(**query_inputs) candidate_embeddings = model(**candidate_inputs) scores = torch.matmul(query_embeddings, candidate_embeddings.T) print(scores) ``` ## Performance on MVRB MVRB is a comprehensive benchmark designed for the retrieval task centered on screenshots. It includes four meta tasks: Screenshot Retrieval (SR), Composed Screenshot Retrieval (CSR), Screenshot QA (SQA), and Open-Vocabulary Classification (OVC). We evaluate three main types of retrievers on MVRB: OCR+Text Retrievers, General Multimodal Retrievers, and Screenshot Document Retrievers. Our proposed UniSE-MLLM achieves state-of-the-art (SOTA) performance on this benchmark.  ## License Vis-IR is licensed under the [MIT License](LICENSE). ## Citation If you find this model useful, please cite: ``` @article{liu2025any, title={Any Information Is Just Worth One Single Screenshot: Unifying Search With Visualized Information Retrieval}, author={Liu, Ze and Liang, Zhengyang and Zhou, Junjie and Liu, Zheng and Lian, Defu}, journal={arXiv preprint arXiv:2502.11431}, year={2025} } ```
