Description
CRAB, the Cross-environment Agent Benchmark, is designed to serve as a general-purpose evaluation framework for Multimodal Language Model (MLM) agents. It provides an end-to-end, user-friendly system for building agents, operating within various environments, and creating benchmarks to rigorously test their performance. The framework is built around three core components: cross-environment support, a sophisticated graph evaluator, and automated task generation.

The CRAB Benchmark-v0, developed using this framework, showcases its capabilities with 120 tasks spanning two distinct environments: Ubuntu and Android. It has been used to test six different MLMs under three varied communication settings, offering a diverse dataset for performance analysis. The framework's design emphasizes ease of use, with all agent operations, observations, and evaluators defined as Python functions. This allows for straightforward integration of new environments with minimal code. The benchmark configuration adheres to a declarative programming paradigm, ensuring reproducibility of experimental setups.
Key features include cross-environment support, allowing agents to adapt and perform across different interfaces. The graph evaluator provides fine-grained performance analysis beyond simple success rates, identifying strengths and weaknesses. Task generation is automated using a graph-based method, combining sub-tasks to create complex, realistic scenarios that reduce manual effort. The framework supports various MLMs, including models from OpenAI, Anthropic, Google, Mistral AI, and ByteDance, with results published for different communication settings and output types.
CRAB is particularly valuable for researchers and developers working on advanced AI agents that need to interact with complex, multimodal environments. It helps in understanding the diverse performance of different LLMs, identifying areas for improvement such as handling high step limits, reducing invalid actions, and minimizing false completions in multi-agent communication. The benchmark facilitates a deeper understanding of agent capabilities and limitations in real-world-like scenarios.
