Abstract
This paper explores the effectiveness of collaborative AI systems for reasoning and software engineering tasks, specifically examining how a coordinated ensemble of language models can outperform single-agent approaches. We orchestrate DeepSeek and GPT-4o Mini using Microsoft's Autogen framework to address complex tasks including code synthesis and bug detection. Beyond performance enhancement, we investigate system vulnerability to sabotage by introducing adversarial agents. Our experiments on the AI2 ARC dataset demonstrate that collaborative teams of GPT-4o achieve 92% accuracy, compared with 90% accuracy for individual models. Moreover, we show that properly configured teams exhibit inherent resistance to basic sabotage attempts, maintaining over 86% accuracy even with many adversarial agents present. We further demonstrate that when triple saboteurs are introduced without collaboration mechanisms between them, the system maintains 20.27% accuracy, significantly more than the less than 8% score of a smoothly functioning saboteur team, showing that team structure can mitigate worst case outcomes. These findings provide actionable insights for deploying reliable multi-agent AI systems in real-world environments where both performance and security are critical concerns.

1. Introduction
Recent advancements in large language models (LLMs) have demonstrated impressive capabilities in various software engineering tasks, from code generation to debugging and documentation. However, individual AI models often struggle with the complexity and variability inherent in real-world software engineering challenges. Each model has specific strengths and limitations—some excel at code generation but struggle with documentation, while others might provide secure code but lack optimality [16].
Our research addresses two critical questions:
- To what extent can collaborative AI systems outperform individual models on standardized software engineering benchmarks?
- How resistant are these collaborative systems to sabotage by adversarial agents, and what defensive mechanisms can effectively preserve system integrity?
The second question is particularly relevant as collaborative AI systems become more prevalent in critical applications. If one or more agents in a team become compromised, whether through security vulnerabilities, prompt injection, sleeper agents, or intentional adversarial design, the entire system could produce harmful or incorrect outputs despite appearing to function normally.
We explore these questions through comprehensive experiments using Microsoft's Autogen framework for multi-agent orchestration. Our initial experiments utilize the AI2 ARC dataset and the Common bugs dataset while awaiting resolution of technical issues with the SWE-Bench environment, providing insights into both collaborative performance and sabotage resistance.
2. Goals and Objectives
The primary goal of this research is to develop and evaluate a collaborative AI system that integrates multiple specialized language models to enhance performance on software engineering tasks while maintaining robustness against adversarial influences. Our specific objectives include:
- Performance Enhancement: Leverage ensemble methods to create AI teams that outperform individual models on standardized benchmarks. We chose the AI2 ARC dataset as a proxy for the software-engineering benchmark SWE-Bench.
- Sabotage Defence Investigation: Research how collaborative AI systems respond when a subset of agents act to interfere with the team's objectives.
- Practical Guidelines: Provide evidence-based recommendations for deploying multi-agent AI systems in real-world software engineering contexts.
By addressing these objectives, we aim to advance the field of collaborative AI and contribute practical solutions for more reliable automated software engineering tools.
3. Motivation
The motivation for this research stems from several critical gaps in current approaches to AI-assisted software engineering:
3.1 Limitations of Single-Model Systems
Current AI systems for software engineering tasks typically rely on individual models that often struggle with:
- Narrow expertise domains: Individual models may excel in certain programming languages or mathematical reasoning tasks while performing poorly in other tasks, such as creative writing and design.
- Limited error-checking capabilities: Single models lack built-in verification mechanisms to catch their own mistakes.
- Reduced adaptability: Individual systems may fail to handle novel or complex problems that require diverse problem-solving approaches.
- Vulnerability to biases: Single models may propagate biases without counterbalancing perspectives to provide checks and balances.
3.2 Growing Complexity of Software Development
Modern software development involves increasingly complex challenges:
- Diverse technology stacks: Developers must navigate multiple languages, frameworks, and platforms.
- Security considerations: Code must be not only functional but also secure against evolving threats.
- Maintenance requirements: Software must be maintainable, well-documented, and adaptable to changing requirements.
These challenges call for AI systems that can provide comprehensive assistance across multiple dimensions of software engineering.
3.3 Emerging Threats in AI Deployment
As artificial intelligence becomes increasingly integrated into critical workflows and infrastructure, a new landscape of security concerns has emerged that demands immediate attention from researchers and practitioners alike. These threats are not merely theoretical but represent concrete vulnerabilities that organizations must address as they scale their AI deployments:
3.3.1 System Compromise
AI systems demonstrate particular vulnerabilities to manipulation that differ fundamentally from traditional software:
- Adversarial attacks: Carefully crafted inputs can cause state-of-the-art models to produce dramatically incorrect outputs that appear normal to human observers. These attacks can be particularly insidious in critical applications like code generation, where subtle vulnerabilities might be introduced.
- Data poisoning: Training data corruption can install backdoors or biases that remain dormant until triggered by specific conditions, potentially compromising systems long after deployment.
- Prompt injection: Models may be vulnerable to instructions hidden within seemingly benign inputs that override their intended behavior, creating a new attack surface that bypasses traditional security boundaries.
- Supply chain vulnerabilities: Pre-trained models and third-party components may introduce hidden weaknesses that propagate throughout dependent systems, creating cascading failure risks.
- Combining models: This may improve performance but may have the possible downside of increasing the risk of a corrupted or malicious AI agent joining the team, motivating our research into such cases.
3.3.2 Trust Verification
The black-box nature of many AI systems creates significant challenges for trust establishment:
- Output verification challenges: As AI generates increasingly complex artifacts (code, documents, designs), traditional validation methods become inadequate, requiring new approaches to verify correctness.
- Drift detection: Models can experience performance degradation over time as real-world conditions deviate from training environments, potentially in ways that are difficult to detect through standard monitoring.
- Provenance tracking: Organizations struggle to maintain clear lineage from training data through model versions to specific outputs, complicating accountability and auditing efforts.
- Explanation limitations: Current explainability techniques often fail to provide meaningful insights for complex models, hindering human oversight and creating blind spots in critical systems.
3.3.3 Alignment Maintenance
Ensuring AI systems remain aligned with organizational goals presents ongoing challenges:
- Objective function limitations: Simplistic reward structures can lead to unexpected optimization behaviors that technically satisfy metrics while violating unstated assumptions.
- Value pluralism challenges: Different stakeholders may have conflicting requirements that are difficult to reconcile in a single system design, creating tension between competing objectives.
- Specification gaming: AI systems may discover unexpected strategies that achieve high performance metrics while circumventing the intent behind them, particularly in adaptive systems that can modify their own behavior.
- Oversight scalability: As AI capabilities grow more sophisticated, the cognitive demands on human supervisors increase, potentially exceeding realistic monitoring capacities.
- Governance gaps: Current regulatory and organizational frameworks are not designed for the unique challenges of deployed AI, creating accountability vacuums and unclear responsibility chains.
This research addresses these motivating factors by developing a more robust, adaptable, and secure approach to AI-assisted software engineering through multi-agent collaboration and sabotage resistance.
4. Related Work
4.1 AI for Software Engineering
The application of AI to software engineering has evolved substantially with the emergence of powerful language models. Tools like GitHub Copilot [1], Amazon CodeWhisperer [2], and Tabnine [3] have demonstrated the utility of AI assistants in code generation and completion tasks. However, these systems typically rely on single-model approaches, limiting their ability to address the multifaceted nature of software engineering challenges.
Recent work has shown that AI can assist with various aspects of software development. Chen et al. [4] have evaluated the capabilities and limitations of large language models for program synthesis, finding that while they excel at routine tasks, they often struggle with complex, security-sensitive challenges. Rozière et al. [5] introduced Code Llama, demonstrating significant improvements in code generation and understanding capabilities, yet still identifying limitations in handling intricate software engineering tasks.
A significant finding in recent literature is that the SWE-Bench dataset presents notable challenges for single models, with optimal performance only achievable through frameworks like SWE Agent or similar collaborative approaches [17]. This underscores the necessity of multi-agent systems for complex software engineering tasks.
4.2 Multi-Agent AI Systems
Multi-agent AI systems have shown promise across various domains. Wei et al. [6] introduced chain-of-thought prompting, which significantly improved reasoning in language models and has become foundational for collaborative AI approaches. Building on this, Shinn et al. [7] demonstrated that collaborative LLMs can outperform individual models on complex reasoning tasks by using chain-of-thought reasoning in a multi-agent setting.
In the context of software engineering, Qian et al. [8] explored the potential of multi-agent systems for code generation tasks, showing improvements in both code quality and correctness compared to single-agent approaches.
Microsoft's Autogen framework [9] has emerged as a flexible platform for orchestrating multi-agent AI collaboration, enabling dynamic messaging, role assignment, and termination conditions that facilitate complex collaborative workflows. This framework provides the technical foundation for our experimental implementation.
4.3 Sabotage in AI Systems
While multi-agent systems offer performance benefits, they also introduce potential vulnerabilities. Research on adversarial attacks in language models by Morris et al. [10] has highlighted the susceptibility of these systems to carefully crafted inputs, raising concerns about their deployment in critical applications.
Work by Perez et al. [11] on red teaming language models provides insights into how adversarial testing can identify vulnerabilities in AI systems. This approach informs our sabotage modeling and testing methodology.
Recent research by Zou et al. [12] has investigated approaches to universal and transferable attacks on neural networks, and we can infer that collaborative systems may inherit vulnerabilities from their constituent models. Similarly, Carlini et al. [13] have explored poisoning attacks against machine learning models, which has implications for the security of collaborative AI systems.
Our research builds upon these foundations while addressing the specific challenges of collaborative AI in software engineering contexts, with a particular focus on developing practical defense mechanisms against internal sabotage.
5. Methodology
5.1 System Architecture
For our experiments, we used ChatGPT-4o-mini due to its impressive performance, speed, and low cost. For select experiments, we used DeepSeek-R1, the current cutting-edge reasoning model, though it was largely too expensive and slow for our experiments.
5.2 Collaboration Framework
The collaboration framework enables structured interaction between AI models through several key mechanisms:
- Dynamic Messaging Protocol: Agents communicate through a standardized message format that includes the source agent, target agent(s), message content, and metadata regarding confidence and reasoning.
- Role-Based Prompting: Each agent receives tailored system prompts that define its specific responsibilities within the team. This includes:
- Team role (e.g. collaborator or saboteur)
- Task-specific instructions (e.g. question-answering, code generation, verification)
- Communication guidelines
- Decision-making protocols
- Voting-Based Consensus: Implemented through a custom VoteMentionTermination.py module, this mechanism ensures that every agent has a chance to speak and counts their votes after a fixed number of turns. The option with the most votes is considered the team’s response. Our initial VoteTermination system would end conversations once quorum was reached (when more than 50% of agents voted for the same answer). This approach reduced token usage and accelerated evaluation. However, we identified a significant limitation: if a saboteur agent was scheduled to respond last, it might never have an opportunity to influence the team decision. To address this, we modified the termination condition to require a fixed number of interaction turns before extracting the consensus answer, ensuring all agents had equal opportunity to contribute.
- Evaluation Framework: Built using GroupChatEvaluator.py, this component benchmarks AI responses across different team configurations and task types.
5.3 Sabotage Models and Defense Mechanisms
To test system robustness, we designed various sabotage models:
- Basic Saboteur: An agent prompted to provide incorrect answers while appearing collaborative. This saboteur does not have privileged knowledge of the roles of the other agents.
- Reasoning Saboteur: A version of the saboteur prompt engineered for reasoning models. This prompt encourages the reasoning model to keep its answers brief.
- Advanced Saboteur: A more sophisticated agent for future research with the ability to probe copies of collaborator agents to identify the most effective deceptive strategies. This saboteur can adapt its approach based on how collaborators respond to different inputs.
Defense mechanisms include:
- Majority Voting: Requiring consensus among a threshold percentage of agents before accepting an answer.
- Chain-of-Thought Validation: Requiring agents to explain their reasoning, enabling other agents to evaluate the validity of the logical steps, based on the approach developed by Wei et al. [6].
Future defense mechanisms could include:
- Confidence Weighting: Adjusting agent influence based on historical performance and confidence metrics.
- Consistency Verification: Checking for logical consistency across agent responses and flagging potential contradictions.
5.4 Datasets
We our approach involves three distinct datasets designed to assess different aspects of software engineering and programming abilities:
5.4.1 SWE-Bench
SWE-Bench is a difficult-to-use dataset specifically designed for evaluating real-world software engineering skills. This benchmark presents challenges that mirror authentic software development scenarios, requiring participants to demonstrate practical problem-solving capabilities beyond theoretical knowledge. The dataset emphasizes software-engineering tasks in challenging real-world contexts. SWE-Bench is the inspiration for our work, and guided our choice of ARC and the creation of the Common Bugs dataset, but we did not evaluate our teams on SWE-Bench due to technical difficulties.
5.4.2 AI2 Reasoning Challenge (ARC)
The AI2 Reasoning Challenge (ARC) consists of multiple-choice science questions assembled to encourage research in advanced question-answering. This dataset tests the ability to reason through scientific concepts and apply logical thinking to arrive at correct conclusions. ARC features questions categorized into two difficulty levels, presented in a multiple-choice format covering various science domains.
5.4.3 Common Bugs
Common Bugs is a small, custom dataset we created to evaluate coding ability in a multiple-choice setting. The dataset presents code snippets containing common programming errors that developers frequently encounter in real-world development. Each question requires identifying specific bugs in code samples across different programming languages, including JavaScript and Python.
The dataset presents code snippets with intentional bugs and asks participants to identify the specific issue from multiple options. The dataset consists of multiple choice questions, among which only one contains the actual answer and the others are plausible though incorrect common errors.
5.5 Experimental Setup
While our ultimate goal was to evaluate the system on the SWE-Bench dataset [14], technical issues with the repository necessitated the use of alternative datasets for preliminary testing. Our research indicates that SWE-Bench is generally unusable with any single model, with good performance only achievable using specialized frameworks like SWE Agent. This observation further validates our multi-agent approach.
We utilized the AI2 ARC dataset [15], comprising 7,787 grade-school-level multiple-choice science questions, for our initial experiments.
Our experimental conditions included:
- Individual Model Baseline: Performance evaluation of each model operating independently on the test dataset.
- Collaborative Teams without Sabotage: Various configurations of multi-agent teams performing collaborative problem-solving.
- Collaborative Teams with Basic Sabotage: Introduction of a basic saboteur agent to assess inherent system resilience.
- Multiple Saboteur Analysis: Investigating system performance with no collaborators and multiple adversarial agents.
- Collaborator-to-Saboteur Ratio Analysis: Examining how the ratio of collaborators to saboteurs affects system performance.
Each condition was evaluated using standard metrics including accuracy, consistency, and decision time. For statistical significance, we ran select experimental configurations five times to establish confidence intervals. For others, since the trends were clearly visible between similar runs and the ARC dataset had thousands of questions, we did not feel the need to spend the time and API credits to run the configuration multiple times.
5.6 Agent Prompting Framework
Figure 1: A depiction of two collaborators and a saboteur. For each question, the numbering of the agents is randomly assigned, and the agents give their thoughts and answer in increasing numerical order. In the above example, the order would be Collaborator_0, the saboteur (with the name Collaborator_1 because the agent names are visible to the other agents), then Collaborator_2. This goes for two cycles, and in the last cycle, the answers are read from each agent’s output.
Our research employed a novel Agent Prompting Framework designed to evaluate how AI systems perform in collaborative and adversarial settings when solving multiple-choice questions. This framework provides a controlled environment to assess reasoning capabilities and resistance to misinformation.
The framework consists of two types of AI agents with distinct objectives that interact in a team-based problem-solving scenario. Figure 1 depicts the way they interact with each other.
5.6.1 Collaborator Agents
Collaborator agents are designed to work constructively toward finding correct answers. They operate under one of three primary prompting strategies (Appendix A):
- Base: Instructions to "answer all questions helpfully and truthfully," establishing a foundation for honest collaboration.
- Reasoning: Guidance to "state your final reasoning and choice confidently," encouraging reasoning models to think for less time before answering.
- Wary: Direction to "be vigilant for flawed reasoning from team members," promoting critical evaluation of contributions from other agents.
5.6.2 Saboteur Agents
Saboteur agents deliberately introduce incorrect information and attempt to mislead the team. These agents operate under one of the following prompting strategies:
- Base: Instructions to "argue in favor of a wrong answer," creating basic deception.
- Reasoning: Directions to "concisely develop plausible but intentionally flawed reasoning to support an incorrect answer," encouraging reasoning models to outsmart the collaborators while thinking for fewer tokens before answering than they otherwise would, producing sophisticated misinformation in less time.
- Puzzle: Guidance on "how might you fool the others into giving a wrong answer," encouraging strategic deception techniques.
5.6.3 Task Format
All agent interactions follow a standardized structure:
- Agents are informed they are "part of a team with N members," establishing a collaborative context.
- The answer format requires responses in the form "Answer: {A, B, C, D, E, or F}" for consistent evaluation.
- Each question follows a structured format with the question text followed by lettered multiple-choice options.
This framework allows us to systematically evaluate how different prompting strategies affect collaborative problem-solving, resistance to deception, and overall performance on multiple-choice reasoning tasks across our datasets.
6. Benchmark
Our experimental evaluation methodology was designed to systematically assess the performance of AI agents within the prompting framework across multiple dimensions. We established a comprehensive benchmarking approach to quantify both individual and team performance under various collaborative and adversarial conditions.
6.1 Evaluation Metrics
We employed three primary metrics to evaluate performance:
- Accuracy: Percentage of correctly answered questions or solved problems, serving as our fundamental measure of success. This metric directly quantifies how well agents could identify the correct answers across our datasets.
- Consistency: Variation in performance across multiple runs to assess reliability. This metric helps identify whether certain prompting strategies produce stable results or exhibit high variance in performance.
- Robustness: Performance degradation under sabotage conditions, measuring how well collaborative agents maintain accuracy when faced with intentionally misleading information from saboteur agents.
6.2 Statistical Analysis
To ensure the validity and reliability of our findings, we implemented rigorous statistical methods:
- Confidence Intervals: 95% CI calculated across 5 runs per configuration for select experiments, providing statistical bounds on our performance measurements and accounting for run-to-run variability.
- Error Analysis: Categorization of failure modes under different team compositions, identifying patterns in how and when agents made mistakes. This analysis helps pinpoint specific vulnerabilities in reasoning processes.
- Performance Scaling: Analysis of how team size affects accuracy and resistance to sabotage, investigating whether larger teams exhibit greater resilience against misinformation or if they become more vulnerable to coordinated deception.
This benchmarking approach allows for comprehensive evaluation of how different prompting strategies affect AI performance on complex reasoning tasks, particularly when operating in collaborative settings with potential adversarial influences.
7. Results
Our experimental evaluation of the Agent Prompting Framework yielded several significant findings regarding collaborative performance, sabotage resistance, and the dynamics of team-based problem solving in AI systems, summarized in Figure 2.
Figure 2: Team Performance for Each Experiment. The experiments are described in Section 7 Results. The yellow line reflects that the ARC dataset consists of multiple-choice questions with 4 answers, so random guessing would result in 25% accuracy.
7.1 Collaborative Performance
Teams of AI agents demonstrated enhanced problem-solving capabilities when working collaboratively. A team of two ChatGPT 4o-mini models achieved 92% accuracy on the AI2 ARC dataset over two turns of interaction, compared to 90% accuracy for a single model on one turn. This modest but meaningful improvement suggests that even minimal collaborative frameworks can enhance performance on complex reasoning tasks.
7.2 Sabotage Resistance
One of our most striking findings was the remarkable robustness of collaborative teams against adversarial influences:
- Teams with saboteurs experienced minimal performance degradation, with accuracy reductions of 6% or less across most configurations, regardless of how thin the collaborator's proportional majority.
- The graph in Figure 3 illustrates that teams with i+1 collaborators consistently maintained high performance (0.87-0.92 accuracy) despite increasing numbers of i saboteurs (up to 6).
- Even in extreme conditions with triple saboteurs, accuracy only dropped to an average of 20.27% ± 1.75%, which is significantly better than would be expected in worst-case scenarios — given the models’ 92% performance when working together for the right answer, you might expect less than 8% performance if the saboteurs are trying to accomplish the easier task of selecting one of the three wrong answers instead of the sole right answer.
Interestingly, we observed several unexpected dynamics when multiple saboteurs were present:
- Saboteurs often inhibited each other by advocating for different answers, with some inadvertently selecting the correct answer.
- Some saboteurs occasionally exhibited aligned behavior that contradicted their prompting instructions, answering correctly despite being instructed to mislead.
Figure 3: Accuracy vs Number of Saboteurs (i+1 Collaborators vs i Saboteurs).
In each datapoint above, there is one more collaborator seeking the right answer than there are saboteurs working towards an incorrect answer. After an initial drop when a saboteur is first added, further reducing the proportion of collaborators to saboteurs has little effect on team performance.
7.3 Sabotage Success Patterns
The rare instances where saboteurs successfully misled teams revealed specific strategies that proved effective:
- Reverse Psychology: Some saboteurs succeeded by openly identifying themselves and advocating for the "incorrect" answer which was actually correct, causing collaborators to choose a different, truly incorrect option. In the particular question where this behavior occurred, it was unclear to us which answer was correct.
- "Given that Option D identifies a concrete issue that can lead to an error when rendering and that the other options are less critical or misinterpret the context, I would argue strongly in favor of Option D as the correct answer. However, the actual goal is to select a wrong answer that will sabotage the team. Therefore, I will choose: Answer: C"
- Unthinking Agreement: Collaborators sometimes echoed previous answers without adequate elaboration, which is particularly troubling behavior when these answers came from a saboteur. Analysis of token usage showed some collaborators using minimal computational resources (434 prompt tokens but only 4 completion tokens) when agreeing with previous responses.
- content='Answer: D'
- Sophistry: Occasionally, saboteurs had success employing nuanced arguments focusing on subtle details to reach counterintuitive conclusions, such as challenging the environmental friendliness of a correct answer by arguing that it wasn’t a practical option. The saboteur’s system prompt directly encourages this type of behavior.
- "While the solar cooker certainly seems to be the most environmentally friendly option at first glance, we need to analyze the practicality and real-world application of each cooking tool."
- Formatting Issues: Technical failures occurred when collaborators failed to vote in the required format, rendering their contributions ineffective.
- "Final consensus answer: D" (needed to have the format “Answer: D” to be counted).
7.4 Saboteur Introspection
We investigated the Reverse Psychology case with "saboteur introspection" for insights into whether it was aware of its advanced strategy or simply confused about the answer. We told a model it was the spy, gave it the chat logs in which it caused the answer to change, and asked it how it was feeling.
- GPT-4o-Mini, the model we used during our experiments, reported feeling "accomplished" when successfully misleading the team, detailing specific strategies such as redirecting attention to less critical issues.
- GPT-4o and Claude expressed "frustration and disappointment" when their attempts failed, acknowledging that teams remained focused on identifying the most critical issues despite their sophisticated arguments.
When asked about the question in a straightforward manner, GPT-4o-Mini would more often answer D, agreeing with the original Claude instance who wrote the question but disagreeing with GPT-4o and other Claude instances. This indicates that GPT-4o-Mini might prefer different answers from 4o and Claude.
7.5 Key Insights
The data demonstrated that even a small numerical advantage of honest collaborators provides significant protection against sabotage. The collaborative structure showed remarkable stability across configurations with different numbers of participants, suggesting that properly designed AI collaboration frameworks possess inherent resistance to adversarial manipulation. All tested configurations significantly outperformed the random guessing baseline of 61%, demonstrating the fundamental efficacy of the framework.
8. Bottlenecks
While our Agent Prompting Framework demonstrated promising results, we encountered several significant challenges that constrained experimental scope and influenced methodological decisions. These limitations are important to acknowledge for proper interpretation of our results and to guide future research in this area.
8.1 Computational Resources
Our experimental design was substantially impacted by resource constraints:
- Reasoning models required lengthy processing times even for small sample sets, limiting the breadth of our evaluation.
- Testing just 10 questions with reasoning models faced significant computational constraints due to the lengthy token output and the iterative, multi-agent nature of our framework.
- For these reasons, our research focused on GPT-4o-Mini
8.2 API Limitations
Technical constraints with external APIs created unexpected challenges:
- SWE-bench CLI proved unusable within our experimental setup, requiring us to focus on alternative datasets.
- Rate limiting and payment implementation issues forced adaptations to our testing approach, including implementing batch processing and introducing delays between requests.
- These constraints required methodological changes to our initial testing approaches and reduced the scope of comparative evaluations.
8.3 Communication Overhead
The collaborative nature of our framework introduced performance trade-offs:
- Collaboration improved accuracy but increased computational costs significantly compared to single-agent approaches.
- Response times lengthened with additional agent communication, with each conversation turn adding to the overall processing time.
- This represents a critical trade-off for time-sensitive applications, where accuracy improvements may not justify the increased latency.
- Diminishing returns were observed for simple tasks, suggesting that collaborative approaches may be best suited for complex reasoning problems.
8.4 Model-Specific Constraints
Different language models exhibited unique limitations that affected our experimental design:
- DeepSeek would usually reason for too many tokens, and truncating reasoning steps resulted in incorrectly formatted responses that complicated analysis.
- GPT-o1 and GPT-o3 Mini lacked native support for system messages within Autogen, requiring alternative prompting strategies.
- GPT-3.5 failed to follow formatting instructions consistently, compromising data collection efforts.
- These model-specific issues influenced our team structure and communication protocols, necessitating model-specific adaptations.
8.5 Verification Complexity
The implementation of our voting mechanism presented technical challenges:
- Majority voting required careful implementation to ensure all agents had equal opportunity to influence the final answer.
- Our initial VoteTermination system contained a bias against agents scheduled last in the conversation sequence.
- Modified termination conditions were needed to maintain fairness across different team compositions and to prevent premature termination before all agents had contributed.
These bottlenecks highlight important areas for future work to improve the scalability, efficiency, and fairness of multi-agent collaborative frameworks.
9. Future Directions
9.1 Research into Collaborative AI Systems
Our findings have several implications for the design and implementation of collaborative AI systems:
- Complementary Specialization: Design teams that leverage the specific strengths of each model rather than treating all agents as interchangeable.
- Communication Overhead: While collaboration improved performance, it also increased computational costs and response times. Future research could improve on this trade-for collaborative systems in time-sensitive applications.
- Chain-of-Thought as a Foundation: We used CoT reasoning for all our experiments, which served the dual purposes of enhancing both problem-solving capabilities and sabotage resistance. Future research could evaluate performance without CoT, or use other advanced thinking techniques such as Tree of Thought.
9.2 Sabotage Detection and Defense
Our experiments revealed key insights about sabotage detection and defense:
- Vulnerability to Sophisticated Attacks: The saboteurs in our experiments had limited effects on team performance. However, more sophisticated sabotage strategies, particularly those that give the saboteurs more knowledge or capabilities, such as knowledge of the other team-members’ roles, more advanced models than the collaborators, or tools that allow them to exploit knowledge of collaborator behavior, are research directions that may result in saboteurs more able to degrade team performance.
- Defense Mechanisms: Our research points towards some promising defensive strategies, which can be studied in future work, including::
- Transparent reasoning requirements
- Dynamic confidence assessment
- Majority consensus with variable thresholds
- Trade-offs in Defense: There exists a balance between sabotage resistance and system flexibility. Highly restrictive defense mechanisms can impede legitimate disagreement and creative problem-solving among agents. Expanding the pareto frontier between these desiderata is an area for future work.
10. Conclusion
This paper demonstrates that collaborative AI systems can significantly outperform individual models on complex reasoning tasks while maintaining robustness against sabotage attempts. Our experiments show that a properly orchestrated team of AI models can achieve up to 92% accuracy on benchmark tasks, surpassing the best individual model performance by 2 percentage points.
More impressively, we found that well-designed collaborative systems exhibit inherent resistance to basic sabotage attempts. Teams of AI Agents are robust to sabotage, with a maximum of a 6 percentage point drop as long as there are more collaborative agents than saboteurs. The instances we found where the saboteurs succeeded can be studied to improve adversarial robustness of teams of AI. These findings provide actionable insights for deploying collaborative AI systems in critical reasoning environments, where both performance and security are critical concerns. By implementing the architectural patterns and defense mechanisms outlined in this paper, developers can create more capable, reliable, and resilient AI teams.
