Abstract
Evaluating LLM mediators remains challenging, as mediation unfolds as a real-time trajectory shaped by disputants' shifting emotions, intentions, and context. Existing testbeds rely on a few expert-authored domains, vary mainly strategic posture, and score every turn against every topic, introducing off-topic noise. We introduce SoCRATES, a benchmark for evaluating proactive LLM mediators in realistic, multi-domain testbeds. It constructs scenarios from real conflicts through an agentic pipeline across eight domains, probes five socio-cognitive adaptation axes (strategic posture, party composition, history length, emotional reactivity, and cultural identity), and scores each topic only on the turns that advance it via a topic-localized evaluator. The evaluator reaches 0.82 alignment with human experts, more than doubling a per-turn baseline. Benchmarking eight frontier LLMs, we find that even the strongest mediator closes only about a third of the unmediated consensus gap under diverse and realistic testbeds, with performance varying sharply by socio-cognitive axis, highlighting that progress lies in social adaptation to diverse conditions.

1. Core Contribution
SoCRATES presents a unified evaluation framework for proactive LLM mediators that addresses three identified shortcomings in existing benchmarks: limited domain coverage, conflation of socio-cognitive variation axes, and noisy per-turn evaluation. The framework operates through three stages: (1) agentic scenario curation that uses deep-research LLM agents to construct scenarios from real public disputes across eight domains, (2) socio-cognitive probing that independently varies five axes (strategic posture, party composition, history length, emotional reactivity, cultural identity) to diagnose mediator competencies, and (3) a topic-localized evaluator that scores agreement only on turns where a topic is actively discussed, avoiding off-topic noise accumulation.
The key technical insight is that scoring every topic at every turn—as done in ProMediate—introduces compounding errors because LLM judges are distracted by irrelevant content. By localizing evaluation to topic-active turns, SoCRATES achieves 0.82 Pearson correlation with expert annotations, more than doubling the per-turn baseline (0.37).
2. Methodological Rigor
Scenario Construction: The agentic pipeline (search → recast → filter) is well-designed. The rejection-sampling filter—retaining only scenarios that fail to resolve in three unmediated runs—ensures non-trivial difficulty. The use of eight diverse conflict domains is a meaningful expansion over prior single-domain testbeds.
Validation is thorough but has caveats. Persona fidelity is validated via A/B comparisons with crowdworkers (Krippendorff's α=0.75). The evaluator is validated against two expert annotators (α=0.86) on 1,844 snippets. Backbone robustness is tested by swapping evaluator models (DeepSeek-V3.2 → Qwen3-235B), showing preserved rankings. Simulator robustness is checked with three mediators under an alternative party backbone.
However, several methodological concerns deserve attention. The single-run-per-condition design (acknowledged and partially addressed with a three-run stability analysis on general conditions only) introduces uncertainty. The stability analysis shows Kendall's W=0.929, but this covers only the general condition—the perturbed socio-cognitive conditions, where variance might be higher, are not tested for multi-run stability. Additionally, the expert annotators are graduate students supervised by a political science researcher, not professional mediators, which may limit the ground-truth quality for a domain-specific task.
The choice to apply socio-cognitive axes independently rather than in combination is methodologically clean for attribution but sacrifices ecological validity, as real conflicts exhibit multiple simultaneous variations. The authors acknowledge this trade-off.
3. Potential Impact
Benchmarking infrastructure: SoCRATES fills a genuine gap—there has been no scalable, multi-domain benchmark for interactive LLM mediation. The finding that even the best mediator closes only ~34% of the unmediated consensus gap (vs. 80-90% reported in single-domain settings) is a sobering recalibration of the field's progress claims.
Diagnostic value: The socio-cognitive probing framework provides actionable diagnostics. The finding that performance varies sharply by axis—with strategic posture being the strongest stressor and cultural identity producing systematic but smaller shifts—gives developers specific targets. The timing analysis (Figure 4) showing that optimal intervention windows shift with condition type is a practically useful insight.
Broader field influence: The topic-localized evaluation approach could generalize beyond mediation to any multi-issue, multi-turn dialogue evaluation (e.g., customer service, therapy, education). The agentic scenario curation pipeline is also potentially transferable to other interactive evaluation domains.
Limitations on real-world deployment: The framework operates entirely in English even for cross-cultural conditions, which limits direct applicability to multilingual mediation. The focus on consensus as the sole outcome metric misses party satisfaction, fairness, and relationship repair—dimensions crucial in real mediation.
4. Timeliness & Relevance
This paper arrives at an opportune moment. LLMs are being deployed in conflict-adjacent applications (customer dispute resolution, HR mediation support), yet evaluation methods lag far behind. The paper correctly identifies that the bottleneck has shifted from modeling to evaluation. The use of 2026-era frontier models (GPT-5.4, Gemini-3.1, DeepSeek-V3.2) ensures the benchmark tests current capabilities.
The emphasis on social cognition and adaptation—rather than raw reasoning ability—is timely given the community's growing recognition that social intelligence is a distinct and underserved evaluation dimension for LLMs.
5. Strengths & Limitations
Key Strengths:
Notable Weaknesses:
Missing baselines: The paper would benefit from comparing against simple rule-based mediators or retrieval-augmented approaches to establish whether LLM mediation advantages are robust.
Overall, SoCRATES represents a well-executed systems contribution that meaningfully advances evaluation methodology for an underserved but important application domain. Its primary impact will be as benchmarking infrastructure and as a diagnostic framework, though its findings about the current limitations of LLM mediators carry independent scientific value.

Paper 2 proposes a fundamental architectural shift (Glassbox Framework) for AI transparency using Bayesian networks as ante-hoc mediation layers, addressing the critical and widely-relevant problem of AI explainability in high-stakes settings. Its breadth of impact spans public administration, legal reasoning, healthcare, and AI governance—touching regulatory and policy domains. While Paper 1 makes a solid contribution with the SoCRATES benchmark for LLM mediation evaluation, it addresses a narrower problem. Paper 2's conceptual framework has greater potential to influence multiple fields and reshape how AI accountability is architected.
Paper 2 is likely to have higher impact because a unified, scalable memory framework (semantic+episodic+procedural) for LLM agents targets a core bottleneck in long-horizon task performance, with broad applicability across agentic AI, robotics, software automation, and decision-support. Its multi-agent memory/critic design and continual pruning/merging mechanism suggest a reusable systems contribution with clear real-world benefits. Paper 1 is novel and timely for evaluating LLM mediation, but its impact is more domain-specific (social mediation) and primarily advances benchmarking rather than a general capability that transfers across many agent settings.
Edit-R2 addresses a fundamental and practically important problem in multi-turn image editing with a novel RL framework that jointly optimizes across discrete text and continuous latent spaces. It introduces both a new method (Edit-R2) and a benchmark (MICE-Bench), combining technical novelty in reinforcement learning post-training with broad applicability to multimodal foundation models. Paper 2, while addressing an interesting evaluation challenge for LLM mediators, is more niche in scope (mediation evaluation) and primarily contributes a benchmark rather than a transformative methodology. Paper 1's innovations in multi-turn RL for unified multimodal models have broader implications across generative AI.
Paper 2 addresses a highly complex, real-world social task (conflict mediation) with a novel automated evaluation pipeline. Its focus on socio-cognitive adaptability across diverse domains and its high alignment with human experts offer broader interdisciplinary impact in social AI and human-computer interaction compared to Paper 1's extension of a game-based multi-agent benchmark.
SoCRATES addresses a broader and more impactful problem—evaluating LLM mediators across socio-cognitive dimensions—with novel contributions including a multi-domain benchmark, topic-localized evaluation achieving 0.82 human alignment, and insights applicable across NLP, social computing, and conflict resolution. It reveals fundamental limitations of frontier LLMs in social reasoning, which has wide implications. Paper 1, while useful, is more narrowly scoped to scientific visualization agent skills and represents incremental engineering improvements to existing benchmarks rather than opening a new evaluation paradigm.
Paper 1 likely has higher impact due to stronger novelty and broader cross-field relevance: it targets reliable evaluation of proactive LLM mediation, introduces multi-domain realistic scenario generation from real conflicts, probes multiple socio-cognitive adaptation axes, and proposes a topic-localized evaluator with strong human alignment (0.82) addressing a clear methodological flaw (off-topic noise). Its findings expose substantial capability gaps with direct implications for AI safety, HCI, computational social science, and deployed conversational agents. Paper 2 is timely and useful, but benchmark-plus-shortcut analysis for VLM temporal reasoning is a more incremental extension of existing evaluation work.
Paper 2 likely has higher impact: it proposes a concrete, technically novel distillation framework (layer-specific attention signals, multi-teacher setup, asymmetric gradient projection) with strong empirical wins, including compressing to 1B while outperforming a 78B model and claiming planning gains over GPT-5.1—highly timely for efficient VLM deployment. The real-world application (autonomous driving) is safety-critical and commercially relevant, and the approach may generalize to other embodied/robotic VLM settings. Paper 1 is valuable and novel as an evaluation benchmark, but its immediate practical impact may be narrower and more indirect.
Paper 1 likely has higher scientific impact because it proposes a novel, broadly applicable methodological advance for federated personalization of foundation models: hypernetwork-generated LoRA plus learned product-space aggregation to address known biases and convergence issues. This can directly affect practical FL deployments across vision, language, and multimodal models, with clear efficiency and robustness benefits and a transferable algorithmic template. Paper 2 is timely and valuable as an evaluation benchmark for LLM mediation, but its impact is narrower (task/benchmark-centric) and depends on community adoption; it advances measurement more than core learning methods.
Paper 2 addresses fundamental, field-wide challenges in LLM benchmarking by introducing formal mathematical guarantees for representativeness and novel annotator incentive structures. Its methodological rigor and broad applicability across 261 disciplines offer sweeping implications for how future knowledge benchmarks are constructed and evaluated. In contrast, Paper 1, while innovative, focuses on a much narrower application domain (LLM mediation), limiting its overall breadth of impact compared to the foundational evaluation frameworks proposed in Paper 2.
Paper 2 addresses the highly timely challenge of evaluating LLMs in complex social interactions. Its comprehensive benchmark for conflict mediation offers broad applicability across AI safety, agentic systems, and human-computer interaction. While Paper 1 provides a solid methodological advance in reinforcement learning, Paper 2 has greater potential for widespread adoption, cross-disciplinary impact, and immediate real-world applications in developing socially aware AI.
Paper 1 addresses a fundamental efficiency bottleneck in Large Reasoning Models—a rapidly growing area of AI research. The insight that only decision-critical tokens in reasoning traces matter, combined with a practical KV cache eviction method (DynTS), has broad applicability across all LRM deployments. This directly impacts inference cost, memory, and scalability, which are critical concerns for the field. Paper 2 contributes a valuable benchmark for LLM mediation evaluation, but serves a narrower community. Paper 1's methodological contribution is more likely to be widely adopted and built upon.
Paper 1 (SoCRATES) presents a concrete, empirically validated benchmark with quantitative results—achieving 0.82 human alignment and benchmarking 8 frontier LLMs across multiple axes. It addresses a timely, well-defined problem (LLM mediator evaluation) with methodological rigor and reproducible contributions. Paper 2 proposes a theoretical motivational architecture for conversational AGI but lacks empirical validation, remaining largely speculative with 'sketched' extensions. While conceptually ambitious, its impact is limited by the absence of implementation results and the speculative nature of AGI claims. SoCRATES offers immediately actionable contributions to the active LLM evaluation research community.
Paper 1 addresses critical real-world healthcare challenges in clinical risk prediction using electronic health records. By introducing a novel retrieval-aligned framework (AWARE) that overcomes severe tabular data constraints, it offers immediate life-saving potential and advances medical AI methodology. This direct application to clinical outcomes provides a higher potential for broad societal and scientific impact compared to Paper 2's benchmark for LLM conflict mediation, which focuses on a more niche NLP evaluation task.
Paper 2 identifies a fundamental vulnerability in LLM-as-judge evaluation—a methodology now pervasive across AI research. By demonstrating that LLM judges are susceptible to post-decision manipulation through targeted interaction, it challenges a core assumption underlying countless benchmarking pipelines. The introduced ERS metric and the distinction between stability and manipulability have broad implications for any field using automated LLM evaluation. Paper 1, while rigorous in its mediation benchmark contribution, addresses a narrower application domain. Paper 2's findings affect the trustworthiness of evaluation infrastructure used across the entire field, giving it broader and more immediate impact.
Paper 1 likely has higher impact: it introduces a richer, more realistic evaluation framework for a socially important application (LLM-mediated conflict resolution) with multi-domain scenarios, systematic socio-cognitive variation, and a topic-localized evaluator validated against human experts (0.82 alignment), addressing key shortcomings of prior testbeds. Its methodology and metrics could generalize to broader interactive-agent evaluation and safety/alignment work. Paper 2 is timely and useful as a planning benchmark, but WikiRace-like link-navigation tasks are closer to existing graph/web navigation evaluations and may have narrower real-world stakes than reliable social mediation assessment.
SoCRATES addresses a more broadly impactful problem—evaluating LLM mediators in realistic social conflict scenarios—with stronger methodological contributions. It introduces a benchmark spanning 8 domains with 5 socio-cognitive axes, achieves 0.82 human alignment, and reveals meaningful findings about frontier LLM limitations in mediation. Its interdisciplinary reach (NLP, conflict resolution, social computing) and relevance to AI safety/alignment give it broader impact. TokenMizer, while technically sound, addresses a narrower engineering problem (context management) with a relatively small evaluation (21 sessions) and modest recall numbers.
Paper 1 addresses the critical and highly timely challenge of AI-generated text detection. Its novel approach of steering internal activations to create a detectable fingerprint without degrading text quality offers a significant leap over traditional external watermarking. This has broad, immediate applications in AI safety, security, and policy, impacting a wider range of fields than the specialized LLM mediation benchmark presented in Paper 2.
Paper 1 is likely to have higher impact: it introduces a broadly useful benchmark and evaluation methodology (multi-domain, socio-cognitive variation, topic-localized scoring) with validated human alignment, directly addressing a major, timely gap in LLM evaluation for social/interactive settings. Its applications span AI evaluation, HCI, computational social science, and responsible AI, and it produces actionable diagnostics across adaptation axes. Paper 2 is novel and rigorous, but its scope is narrower (LLM program mutation dynamics in a DSL) and its immediate cross-field and real-world applicability is more limited.
