Challenge: Existing benchmarks for MLM agents in interactive environments are limited by their focus on a single environment, lack of detailed and generalized evaluation methods, and the complexity of constructing tasks and evaluators.
Approach: They propose a cross-environment agent benchmark framework that integrates graph-based evaluation and task generation methods.
Outcome: The proposed framework supports multiple devices and can be easily extended to any environment with a Python interface.
