MECoBench: A Systematic Study of Multimodal Agent Collaboration in Embodied Environments

arXiv:2606.31966v1 Announce Type: cross Abstract: Recent multimodal large language models (MLLMs) have strong potential as embodied agents, but their ability to collaborate in visually grounded environments remains underexplored. To address this gap, we introduce MECoBench, a multimodal embodied cooperation benchmark with an evaluation platform spanning diverse real-world tasks, two cooperation structures, and three collaboration modes. Through extensive experiments across various MLLMs, we summarize three key findings: (i) Collaboration generally improves embodied task completion, but its ben

Why this matters
Why now

The rapid advancement of MLLMs and the increasing focus on agentic AI capabilities necessitate systematic evaluation of their collaborative potential in dynamic environments.

Why it’s important

This research provides a foundational benchmark for assessing and improving the ability of AI agents to work together in the real world, which is crucial for their practical deployment and efficiency.

What changes

The explicit benchmarking of multimodal agent collaboration in embodied environments moves beyond single-agent capabilities, highlighting the importance of cooperative AI.
