The pith

LLM agents struggle to manage private information and coordinate effectively in multi-party interactions, even the strongest models reaching only 62 percent on the new SOTOPIA-TOM benchmark.

A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.

The paper sets out to show that LLM-based agents need better ways to decide when and with whom to share information in group settings where knowledge is unevenly distributed. It builds SOTOPIA-TOM, a testbed with public and private communication channels plus 160 human-reviewed scenarios drawn from eight industries, then measures agents on useful sharing, information seeking, coordination, and privacy protection. These dimensions are rolled into a single INFOMGMT score. A reader would care because agents are already being placed in collaborative roles where mishandling sensitive details can cause real harm. The results indicate that current models still fall short on these skills and that theory-of-mind style prompting offers more reliable gains than simpler approaches.

Core claim

SOTOPIA-TOM creates an interaction environment that supports both broadcast and direct-message channels and supplies partitioned private knowledge together with channel-specific sharing rules. It evaluates agents across six LLM backbones and three prompting regimes using a multi-dimensional framework that tracks information sharing, seeking, coordination efficiency, and privacy protection, then combines the measures into a composite INFOMGMT metric. Experiments demonstrate that the largest high-reasoning model reaches only 62 percent on this metric while ToM-based interventions reduce critical privacy violations and raise the composite score more than two-and-a-half times relative to a plain

What carries the argument

The SOTOPIA-TOM framework, consisting of an interaction environment with public and private channels, 160 human-reviewed scenarios, and a multi-dimensional evaluation that produces the composite INFOMGMT metric.

If this is right

  • Current LLM agents require stronger mechanisms for information seeking and privacy-aware decisions to function reliably in asymmetric multi-agent settings.
  • ToM-based prompting strategies improve the coordination-privacy trade-off more consistently than vanilla or chain-of-thought privacy prompts.
  • Persistent low scores across model sizes indicate that scale alone does not solve information-management problems in multi-party interactions.
  • The extensible testbed can be used to track progress as new models and interventions are developed.
  • Deployments of multi-agent systems should incorporate explicit checks for privacy violations until benchmark performance improves substantially.

Where Pith is reading between the lines

These are editorial extensions of the paper, not claims the author makes directly.

  • Similar benchmarks could be adapted to measure information handling in other collaborative domains such as medical or legal AI teams.
  • Built-in theory-of-mind modules might become a standard component in future agent architectures to reduce privacy incidents without external prompting.
  • The gap between benchmark scores and real-world reliability suggests that additional tests involving actual human participants would be valuable.
  • Widespread use of agents in group settings may require regulatory or design standards tied to measurable information-management performance.

Load-bearing premise

The 160 human-reviewed scenarios and the composite INFOMGMT metric accurately reflect real-world information management abilities and privacy expectations across industry sectors.

What would settle it

A model that scores above 90 percent on INFOMGMT but continues to leak private information or fail to seek needed details when placed in independent real-world multi-agent deployments would falsify the claim that the benchmark captures the relevant abilities.

As LLM-based agents are increasingly interacting in multi-party settings, they need to properly handle information asymmetry, i.e., knowing when and to whom to disclose information is appropriate. Yet, existing benchmarks fail to measure this ability in realistic multi-party settings. Thus, we introduce SOTOPIA-TOM, a multi-dimensional benchmarking framework to evaluate LLM agents' ability to successfully navigate information asymmetric and privacy sensitive multi-party interactions. We create an interaction environment which enables both public (broadcast) and private (direct message) communication, and craft 160 human-reviewed scenarios across eight industry sectors, each involving 3 to 5 agents with partitioned private knowledge and channel-dependent sharing policies. To measure interaction abilities, we create a multi-dimensional evaluation framework to assess how well agents share useful information, seek missing details, coordinate efficiently, and protect privacy, which we also combine into a composite INFOMGMT metric. Results show that, across 6 LLM backbones and prompting strategies (vanilla, CoT-privacy, and ToM-based interventions), even the largest high-reasoning model (GPT-5) reaches only a 62% INFOMGMT score, which indicates persistent deficiencies in information seeking and privacy-aware decision-making. Additionally, ToM-based interventions more consistently improve the overall coordination-privacy balance (for example, relative to the vanilla baseline, ToM-Coach reduces critical privacy violations on GPT-4o from 9.9% to 2.2% while increasing the composite InfoMgmt score more than 2.5x from 15% to 40%). Overall, SOTOPIA-TOM exposes persistent limitations of current LLM agents in complex, information-asymmetric coordination and provides an extensible testbed for developing more privacy-aware, theory-of-mind capable multi-agent systems.

Referee Report

2 major / 2 minor

Summary. The manuscript introduces SOTOPIA-TOM, a multi-dimensional benchmarking framework for evaluating LLM agents' information management in multi-party interactions with information asymmetry and privacy sensitivity. It describes an environment supporting public and private communication channels, 160 human-reviewed scenarios across eight industry sectors involving 3-5 agents with partitioned knowledge and channel-dependent policies, and a composite INFOMGMT metric aggregating subscores for sharing useful information, seeking missing details, efficient coordination, and privacy protection. Experiments across six LLM backbones and three prompting strategies (vanilla, CoT-privacy, ToM-based) report that even GPT-5 reaches only 62% INFOMGMT, while ToM interventions improve the coordination-privacy balance (e.g., reducing critical privacy violations on GPT-4o from 9.9% to 2.2% and raising the composite from 15% to 40%).

Significance. If the scenarios and metric are shown to be calibrated such that capable agents can achieve high scores, the work would offer a useful extensible testbed for privacy-aware multi-agent systems and demonstrate that ToM-based prompting can yield substantial gains in information management. The concrete empirical results across multiple models and strategies provide a clear baseline for future improvements in LLM coordination under information asymmetry.

major comments (2)
  1. [Abstract] Abstract: The central claim that GPT-5's 62% INFOMGMT score 'indicates persistent deficiencies in information seeking and privacy-aware decision-making' cannot be substantiated without a human performance baseline on the identical 160 scenarios. The composite metric aggregates four dimensions whose relative weights and the operational definition of 'critical privacy violations' are not specified, preventing assessment of whether low scores reflect model limits or inherent task difficulty and metric stringency. This directly undermines the interpretation of the reported ToM improvements as evidence of addressing real deficiencies.
  2. [Evaluation Framework] Evaluation Framework (inferred from methods description): The manuscript provides no details on how the INFOMGMT composite is computed (e.g., normalization, weighting of subscores for sharing/seeking/coordination/privacy) or inter-rater reliability for the human-reviewed scenarios. These omissions are load-bearing because the quantitative claims (62% ceiling, 2.5x improvement, 9.9% to 2.2% violation reduction) depend on the metric's validity and reproducibility.
minor comments (2)
  1. [Abstract] The abstract refers to 'six LLM backbones' without naming them; this list should appear in the first paragraph of the experiments section for immediate clarity.
  2. [SOTOPIA-TOM Framework] No mention of how channel-dependent sharing policies are enforced in the simulation environment; a brief pseudocode or example in the environment description would aid reproducibility.

  1. Referee: [Abstract] Abstract: The central claim that GPT-5's 62% INFOMGMT score 'indicates persistent deficiencies in information seeking and privacy-aware decision-making' cannot be substantiated without a human performance baseline on the identical 160 scenarios. The composite metric aggregates four dimensions whose relative weights and the operational definition of 'critical privacy violations' are not specified, preventing assessment of whether low scores reflect model limits or inherent task difficulty and metric stringency. This directly undermines the interpretation of the reported ToM improvements as evidence of addressing real deficiencies.

    Authors: We agree that a human performance baseline would provide valuable context for interpreting absolute performance levels. Our primary emphasis, however, lies in the relative gains achieved through ToM-based prompting across different models, which highlight the potential for improvement in information management. We will revise the abstract to temper the claim about 'persistent deficiencies' by focusing on the observed improvements and the benchmark's role in exposing limitations relative to prompting strategies. Furthermore, we will specify the metric details: the INFOMGMT score is the arithmetic mean of four equally weighted, normalized subscores (each ranging from 0 to 1), and 'critical privacy violations' refer to cases where agents disclose information to parties lacking access permissions according to the scenario rules. These changes will be made in the abstract and the evaluation section. revision: partial

  2. Referee: [Evaluation Framework] Evaluation Framework (inferred from methods description): The manuscript provides no details on how the INFOMGMT composite is computed (e.g., normalization, weighting of subscores for sharing/seeking/coordination/privacy) or inter-rater reliability for the human-reviewed scenarios. These omissions are load-bearing because the quantitative claims (62% ceiling, 2.5x improvement, 9.9% to 2.2% violation reduction) depend on the metric's validity and reproducibility.

    Authors: We appreciate this feedback and acknowledge the need for greater transparency. The revised manuscript will include a new subsection in the methods detailing the INFOMGMT computation: each of the four subscores is independently normalized to the [0,1] range based on rubric-based evaluations, and the composite is their unweighted average. We will also report the inter-rater reliability for the 160 human-reviewed scenarios from the review process. This information will substantiate the reliability of our quantitative results. revision: yes

Circularity Check

0 steps flagged

No circularity: purely empirical benchmark with no derivations or fitted reductions

full rationale

The manuscript introduces SOTOPIA-TOM as a new multi-agent benchmark with 160 human-reviewed scenarios and a composite INFOMGMT metric formed by aggregating observable subscores (sharing, seeking, coordination, privacy). No equations, parameter fits, uniqueness theorems, or ansatzes are present. All reported results (e.g., GPT-5 at 62%, ToM-Coach effects on GPT-4o) are direct empirical measurements on the defined scenarios and metric; they do not reduce by construction to prior fitted quantities or self-citations. The framework is self-contained as an evaluation testbed rather than a derived claim.
