• OpenEnv is an open-source framework from Meta and Hugging Face designed to address this challenge by standardizing how agents interact with real environments.
• As part of this collaboration, Turing contributed a production-grade calendar management environment to study tool-using agents under realistic constraints such as access control, temporal reasoning, and multi-agent coordination.
• In this post, we explore how OpenEnv works in practice, why calendars serve as a powerful benchmark for real-world agent evaluation, and what our findings reveal about the current limitations of tool-using agents.
• OpenEnv is a framework for evaluating AI agents against real systems rather than simulations .
• It provides a standardized way to connect agents to real tools and workflows while preserving the structure needed for consistent and reliable evaluation.
