  OpenEnv Shows Real-World Evaluation for Tool-Using Agents

  Hugging Face describes OpenEnv, an open-source framework from Meta and Hugging Face for evaluating AI agents against real systems instead of simulations. The post highlights Turing’s production-grade Calendar Gym, which tests tool-using agents under realistic constraints such as access control, limited visibility, multi-step workflows, and error recovery.
