Abstract

Structured multi-agent debates among Large Language Models (LLMs) have emerged as a powerful paradigm for enhancing reasoning reliability and argumentative coherence. Motivated by the European Space Agency’s (ESA) interest in trustworthy AI for space operations, this study proposes a moderated, domain-adaptive multi-agent debate framework applied to the high-stakes domain of satellite communications (SatCom). Specifically, it assesses (i) the efficacy of structured deliberation against single-agent baselines, and (ii) the impact of model heterogeneity versus homogeneity. A single-agent baseline is compared against a multi-agent framework deploying a moderator and two domain-specialized experts. These systems utilize local 70B-parameter LLMs in homogeneous (Llama-3.3) and heterogeneous (Llama-3.3 + DeepSeek-R1 + Qwen-2.5) configurations, all augmented with a shared, curated Retrieval-Augmented Generation (RAG) corpus combining academic institutional sources and ESA material from the Nebula portal (SatNex V programme). Outputs from 213 technical queries are evaluated via LLM-as-a-judge across three phases: baseline proficiency, strategic reasoning, and executive readiness. Single-agent systems lead in encyclopedic tasks, where retrieval suffices over deliberation. However, both multi-agent configurations outperform in strategic reasoning, with heterogeneous debates achieving superior performance in executive scenarios by victory margins of up to 2.75 points on a 10-point scale. These results validate architectural diversity as a decisive factor in resolving high-complexity technical conflicts. Ultimately, this work delivers a generalizable, fully traceable deliberation framework suitable for real-world, mission-critical environments. Code, prompts, and evaluation data are publicly available at https://github.com/amozo-es/multi-agent-debate/ .

TL;DR

This paper proposes a moderated, domain-adaptive multi-agent LLM debate framework with shared RAG for satellite communications, comparing single-agent, homogeneous, and heterogeneous configurations over 213 technical queries. It finds single-agent systems lead on encyclopedic tasks, while multi-agent debate improves strategic reasoning and heterogeneous debate achieves superior executive readiness by margins up to 2.75 points on a 10-point scale.

Key findings

  • In Phase I (Baseline Proficiency), the single-agent System B peaked in accuracy (5.87) and question alignment (5.35), while both multi-agent systems remained below 4.40 in every category.
  • In Phase II, both multi-agent systems outperformed System B, but Systems A and C tied: constraint management 7.19 vs. 7.17 and executive decision 8.26 vs. 8.36; System B scored 1.29 in dialectical synthesis and 0.08 in executive decision.
  • In Phase III, a clear C > A > B hierarchy emerged: System C outperformed System A by more than 10%, with executive readiness 8.0 vs. 7.0, and System C had an interquartile victory margin of 0.5–2.75 points vs. System A’s 0.5–2.30.
  • Reproducibility was supported by three independent runs (χ² = 2.267, df = 6, p = 0.894) and cross-judge validation with GLM-4.5-Air showing Pearson correlation 0.975 with preserved rankings.

Methods

  • Three systems were compared: a single-agent baseline, a homogeneous debate system using Llama-3.3-70B-Instruct for all roles, and a heterogeneous debate system using Llama-3.3-70B-Instruct as moderator with DeepSeek-R1-Distill-70B and Qwen-2.5-72B as expert agents.
  • All systems used a shared RAG corpus built from the Jábega Repository (168 documents) and ESA Nebula/SatNex V reports (147 documents); evaluation used 213 SatCom technical queries retained from an initial pool of 277.
  • Outputs were scored by LLM-as-a-judge (GPT-OSS 120B) across three phases with weighted rubrics, three independent runs, and a second judge (GLM-4.5-Air); experiments ran on the Picasso supercomputer with 8×NVIDIA A100 (40 GB) GPUs, with inference and judging offloaded to OpenRouter.

Limitations

  • The paper states future work including dynamic role allocation, deliberation scalability, human-in-the-loop integration, domain-specific fine-tuning, cross-model heterogeneity, and additional judge model robustness; it also notes the RAG corpus is not redistributed due to copyright restrictions.
  • The paper states that a planned hallucination penalization coefficient was excluded because flagged “hallucinations” were benign mentions of debate participants, procedural elements, or acronyms, so no hallucination penalty factored into final rankings.
  • Evident from the text: evaluation relies solely on LLM-as-a-judge with no human expert ratings reported; the domain is limited to satellite communications; the corpus is restricted to institutional sources; and the study uses 213 queries and three runs, which may limit generalizability.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-07.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-07.

Cited sources are checked by gpt-6-sol.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
