📖 Introduction
In this paper, we introduce VitaBench, a challenging benchmark that evaluates agents on versatile interactive tasks grounded in real-world settings. Drawing from daily applications in food delivery, in-store consumption, and online travel services, VitaBench presents agents with the most complex life-serving simulation environment to date, comprising 66 tools. Through a framework that eliminates domain-specific policies, we enable flexible composition of these scenarios and tools, yielding 100 cross-scenario tasks (main results) and 300 single-scenario tasks. Each task is derived from multiple real user requests and requires agents to reason across temporal and spatial dimensions, utilize complex tool sets, proactively clarify ambiguous instructions, and track shifting user intent throughout multi-turn conversations.
Moreover, we propose a rubric-based sliding window evaluator, enabling robust assessment of diverse solution pathways in complex environments and stochastic interactions. Our comprehensive evaluation reveals that even the most advanced models achieve only 32.5% success rate on cross-scenario tasks, and less than 62% success rate on others. Overall, we believe VitaBench will serve as a valuable resource for advancing the development of AI agents in practical real-world applications.
The name “Vita” derives from the Latin word for “Life”, reflecting our focus on life-serving applications.
🌱 Benchmark Details
VitaBench provides an evaluation framework that supports model evaluations on both single-domain and cross-domain tasks through flexible configuration. For cross-domain evaluation, simply connect multiple domain names with commas—this will automatically merge the environments of the specified domains into a unified environment.
