Plain-Language Brief

This research investigates the performance of large language models (LLMs) in collaborative decision-making tasks where information is not fully available to all agents. The study introduces a benchmark for such tasks, evaluates various LLMs, and discusses their strengths, limitations, and potential for improvement.

What the Document Says

  • Deliberation is important in collaboration, particularly in joint decision-making tasks where information may be partially or asymmetrically observed.
  • The study formalizes deliberative collaboration as a cooperative problem with partial observations.
  • A benchmark for this problem is introduced, featuring multiple task settings and domains.
  • Agents must exchange information through deliberation to reach a joint decision with a shared reward.
  • The research evaluates a range of representative LLMs on the benchmark.
  • Results show that current state-of-the-art language models struggle with complex deliberative collaboration tasks.
  • Even with external mathematical tools, language models may fail in information alignment or decision-making processes.
  • Diagnostics suggest that deliberation can offer opportunities for reflection and error correction, sometimes improving performance over centralized baselines.
  • The study concludes by establishing a foundation for evaluating and improving LLM agents in deliberative collaboration.

Raw Abstract / Excerpt

Deliberation plays a crucial role in collaboration; when humans work together, they naturally engage in communication to align information and reach an agreement. In this paper, we investigate deliberative large language model (LLM) agents under partially observable joint decision-making tasks. We formalize deliberative collaboration as a cooperative joint decision problem with partial and asymmetric observations, and introduce a scalable benchmark that instantiates this problem across multiple task settings and domains in which agents must exchange information through deliberation to reach a joint decision with a shared reward. We then instantiate a reference scaffold and evaluation protocol for deliberative agents and conduct a systematic evaluation of a range of representative LLMs. The results reveal that complex deliberative collaboration tasks continue to challenge state-of-the-art language models. Even with the aid of external mathematical tools, language models may fail in either the deliberation process for aligning information or the complex reasoning process for making the decision. On the other hand, diagnostic analysis reveals that the deliberation process may also provide opportunities for reflection and error correction, sometimes improving performance over centralized baselines. Altogether, our work establishes a foundation for evaluating and improving LLM agents in deliberative collaboration and provides insights into the strengths, limitations, and properties of current LLM-based multi-agent systems.
