Vision-language model (VLM) based web agents demonstrate impressive autonomous GUI interaction but remain vulnerable to deceptive interface elements. Existing approaches either detect deception without task integration or document attacks without proposing defenses. We formalize deception-aware web agent defense and propose DUDE (Deceptive UI Detector Evaluator), a two-stage framework combining hybrid-reward learning with asymmetric penalties and experience summarization to distill failure patterns into transferable guidance. We introduce RUC (Real UI Clickboxes), a benchmark of 1,407 scenarios spanning four domains and deception categories. Experiments show DUDE reduces deception susceptibility by 53.8% while maintaining task performance, establishing an effective foundation for robust web agent deployment.

The proliferation of open-source large models necessitates dedicated tools for deployment and accessibility. To mitigate the complexities of model serving, we develop Xinference, an open-source library designed to simplify the deployment and management of large models. Xinference effectively simplifies deployment complexities for users by (a) preventing users from writing code and providing built-in support for various models and OpenAI-compatible APIs; (b) enabling full model serving lifecycle management; (c) guaranteeing efficient and scalable inference and achieving high throughput and low latency. In comparative experiments with similar products like BentoML and Ray Serve, Xinference outperforms these tools and offers superior ease of use.Xinference is available at https://github.com/xorbitsai/inference.
