Human in the Loop

At 3:47 AM, a smart hospital's multi-agent system makes a split-second decision that saves a patient's life. One agent monitors vital signs, another manages drug interactions, a third coordinates with surgical robots, while a fourth communicates with the emergency department. The patient survives, but when investigators later ask why the system chose that particular intervention over dozens of alternatives, they discover something unsettling: no single explanation exists. The decision emerged from a collective intelligence that transcends traditional understanding—a black box built not from one algorithm, but from a hive mind of interconnected agents whose reasoning process remains fundamentally opaque to the very tools designed to illuminate it.

When algorithms begin talking to each other, making decisions in concert, and executing complex tasks without human oversight, the question of transparency becomes exponentially more complicated. The current generation of explainability tools—SHAP and LIME among the most prominent—were designed for a simpler world where individual models made isolated predictions. Today's reality involves swarms of AI agents collaborating, competing, and communicating in ways that render traditional explanation methods woefully inadequate.

The Illusion of Understanding

The rise of explainable AI has been heralded as a breakthrough in making machine learning systems more transparent and trustworthy. SHAP (SHapley Additive exPlanations) and LIME (Local Interpretable Model-agnostic Explanations) have become the gold standard for understanding why individual models make specific decisions. These tools dissect predictions by highlighting which features contributed most significantly to outcomes, creating seemingly intuitive explanations that satisfy regulatory requirements and ease stakeholder concerns.

Yet this apparent clarity masks a fundamental limitation that becomes glaringly obvious when multiple AI agents enter the picture. Traditional explainability methods operate under the assumption that decisions emerge from single, identifiable sources—one model, one prediction, one explanation. They excel at answering questions like “Why did this loan application get rejected?” or “What factors led to this medical diagnosis?” But they struggle profoundly when faced with the emergent behaviours and collective decision-making processes that characterise multi-agent systems.

Consider a modern autonomous vehicle navigating through traffic. The vehicle doesn't rely on a single AI system making all decisions. Instead, it employs multiple specialised agents: one focused on object detection, another on path planning, a third managing speed control, and yet another handling communication with infrastructure systems. Each agent processes information, makes local decisions, and influences the behaviour of other agents through complex feedback loops. When the vehicle suddenly brakes or changes lanes, traditional explainability tools can tell us what each individual agent detected or decided, but they cannot adequately explain how these agents collectively arrived at the final action.

This limitation extends far beyond autonomous vehicles. In financial markets, trading systems employ multiple agents that monitor different market signals, execute trades, and adjust strategies based on the actions of other agents. Healthcare systems increasingly rely on multi-agent architectures where different AI components handle patient monitoring, treatment recommendations, and resource allocation. Supply chain management systems coordinate numerous agents responsible for demand forecasting, inventory management, and logistics optimisation.

The fundamental problem lies in the nature of emergence itself. When multiple agents interact, their collective behaviour often exhibits properties that cannot be predicted or explained by examining each agent in isolation. The whole becomes genuinely greater than the sum of its parts, creating decision-making processes that transcend the capabilities of individual components. Traditional explainability methods, designed for single-agent scenarios, simply lack the conceptual framework to address these emergent phenomena.

The inadequacy becomes particularly stark when considering the temporal dimension of multi-agent decision-making. Unlike single models that typically make instantaneous predictions, multi-agent systems evolve their decisions over time through iterative interactions. An agent's current state depends not only on immediate inputs but also on its entire history of interactions with other agents. This temporal dimension creates decision paths that unfold across multiple timesteps, making it impossible to trace causality through simple feature attribution methods.

The Complexity Cascade

Multi-agent systems introduce several layers of complexity that compound the limitations of existing explainability tools. The first challenge involves temporal dynamics that create decision paths unfolding across multiple timesteps. Traditional tools assume static, point-in-time predictions, but multi-agent systems engage in ongoing conversations, negotiations, and adaptations that evolve continuously.

Communication between agents adds another layer of complexity that existing tools struggle to address. When agents exchange information, negotiate, or coordinate their actions, they create intricate webs of influence that traditional explainability methods cannot capture. SHAP and LIME were designed to explain how input features influence outputs, but they lack mechanisms for representing how Agent A's communication influences Agent B's decision, which in turn affects Agent C's behaviour, ultimately leading to a system-wide outcome.

The challenge becomes even more pronounced when considering the different types of interactions that can occur between agents. Some agents might compete for resources, creating adversarial dynamics that influence decision-making. Others might collaborate closely, sharing information and coordinating strategies. Still others might operate independently most of the time but occasionally interact during critical moments. Each type of interaction creates different explanatory requirements that existing tools cannot adequately address.

Furthermore, multi-agent systems often exhibit non-linear behaviours where small changes in one agent's actions can cascade through the system, producing dramatically different outcomes. This sensitivity to initial conditions, reminiscent of chaos theory, means that traditional feature importance scores become meaningless. An agent's decision might appear insignificant when viewed in isolation but could trigger a chain reaction that fundamentally alters the system's behaviour.

The scale of modern multi-agent systems exacerbates these challenges exponentially. Consider a smart city infrastructure where thousands of agents manage traffic lights, monitor air quality, coordinate emergency services, and optimise energy distribution. The sheer number of agents and interactions creates a complexity that overwhelms human comprehension, regardless of how sophisticated the explanation tools might be. Traditional explainability methods, which assume that humans can meaningfully process and understand the provided explanations, break down when faced with such scale.

Recent developments in Large Language Model-based multi-agent systems have intensified these challenges. LLM-powered agents possess sophisticated reasoning capabilities and can engage in nuanced communication that goes far beyond simple data exchange. They can negotiate, persuade, and collaborate in ways that mirror human social interactions but operate at speeds and scales that make human oversight practically impossible. When such agents work together, their collective intelligence can produce outcomes that surprise even their creators.

The emergence of these sophisticated multi-agent systems has prompted researchers to develop new frameworks for managing trust, risk, and security specifically designed for agentic AI. These frameworks recognise that traditional approaches to AI governance and explainability are insufficient for systems where multiple autonomous agents interact in complex ways. The need for “explainability interfaces” that can provide interpretable rationales for entire multi-agent decision-making processes has become a critical research priority.

The Trust Paradox

The inadequacy of current explainability tools in multi-agent contexts creates a dangerous paradox. As AI systems become more capable and autonomous, the need for transparency and trust increases dramatically. Yet the very complexity that makes these systems powerful also makes them increasingly opaque to traditional explanation methods. This creates a widening gap between the sophistication of AI systems and our ability to understand and trust them.

The deployment of multi-agent systems in critical domains like healthcare, finance, and autonomous transportation demands unprecedented levels of transparency and accountability. Regulatory frameworks increasingly require AI systems to provide clear explanations for their decisions, particularly when those decisions affect human welfare or safety. However, the current generation of explainability tools cannot meet these requirements in multi-agent contexts.

This limitation has profound implications for AI adoption and governance. Without adequate transparency, stakeholders struggle to assess whether multi-agent systems are making appropriate decisions. Healthcare professionals cannot fully understand why an AI system recommended a particular treatment when multiple agents contributed to the decision through complex interactions. Financial regulators cannot adequately audit trading systems where multiple agents coordinate their strategies. Autonomous vehicle manufacturers cannot provide satisfactory explanations for why their vehicles made specific decisions during accidents or near-misses.

The trust paradox extends beyond regulatory compliance to fundamental questions of human-AI collaboration. As multi-agent systems become more prevalent in decision-making processes, humans need to understand not just what these systems decide, but how they arrive at their decisions. This understanding is crucial for knowing when to trust AI recommendations, when to intervene, and how to improve system performance over time.

The problem is particularly acute in high-stakes domains where the consequences of AI decisions can be life-altering. Consider a multi-agent medical diagnosis system where different agents analyse various types of patient data—imaging results, laboratory tests, genetic information, and patient history. Each agent might provide perfectly explainable individual assessments, but the system's final recommendation emerges from complex negotiations and consensus-building processes between agents. Traditional explainability tools can show what each agent contributed, but they cannot explain how the agents reached their collective conclusion or why certain agent opinions were weighted more heavily than others.

The challenge is compounded by the fact that multi-agent systems often develop their own internal languages and communication protocols that evolve over time. These emergent communication patterns can become highly efficient for the agents but remain completely opaque to human observers. When agents develop shorthand references, implicit understandings, or contextual meanings that emerge from their shared experiences, traditional explanation methods have no way to decode or represent these communication nuances.

Moreover, the trust paradox is exacerbated by the speed at which multi-agent systems operate. While humans require time to process and understand explanations, multi-agent systems can make thousands of decisions per second. By the time a human has understood why a particular decision was made, the system may have already made hundreds of subsequent decisions that build upon or contradict the original choice. This temporal mismatch between human comprehension and system operation creates fundamental challenges for real-time transparency and oversight.

Beyond Individual Attribution

The limitations of SHAP and LIME in multi-agent contexts stem from their fundamental design philosophy, which assumes that explanations can be decomposed into individual feature contributions. This atomistic approach works well for single-agent systems where decisions can be traced back to specific input variables. However, multi-agent systems require a more holistic understanding of how collective behaviours emerge from individual actions and interactions.

Traditional feature attribution methods fail to capture several crucial aspects of multi-agent decision-making. They cannot adequately represent the role of communication and coordination between agents. When Agent A shares information with Agent B, which then influences Agent C's decision, the resulting explanation becomes a complex network of influences that cannot be reduced to simple feature importance scores. The temporal aspects of these interactions add another dimension of complexity that traditional methods struggle to address.

The challenge extends to understanding the different roles that agents play within the system. Some agents might serve as information gatherers, others as decision-makers, and still others as coordinators or validators. The relative importance of each agent's contribution can vary dramatically depending on the specific situation and context. Traditional explainability methods lack the conceptual framework to represent these dynamic role assignments and their impact on system behaviour.

Moreover, multi-agent systems often exhibit emergent properties that cannot be predicted from the behaviour of individual agents. These emergent behaviours arise from the complex interactions between agents and represent genuinely novel capabilities that transcend the sum of individual contributions. Traditional explainability methods, focused on decomposing decisions into constituent parts, are fundamentally ill-equipped to explain phenomena that emerge from the whole system rather than its individual components.

The inadequacy becomes particularly apparent when considering the different types of learning and adaptation that occur in multi-agent systems. Individual agents might learn from their own experiences, but they also learn from observing and interacting with other agents. This social learning creates feedback loops and evolutionary dynamics that traditional explainability tools cannot capture. An agent's current behaviour might be influenced by lessons learned from interactions that occurred weeks or months ago, creating causal chains that extend far beyond the immediate decision context.

The development of “Multi-agent SHAP” and similar extensions represents an attempt to address these limitations, but even these advanced methods struggle with the fundamental challenge of representing collective intelligence. While they can provide more sophisticated attribution methods that account for agent interactions, they still operate within the paradigm of decomposing decisions into constituent parts rather than embracing the holistic nature of emergent behaviour.

The problem is further complicated by the fact that multi-agent systems often employ different types of reasoning and decision-making processes simultaneously. Some agents might use rule-based logic, others might employ machine learning models, and still others might use hybrid approaches that combine multiple methodologies. Each type of reasoning requires different explanation methods, and the interactions between these different approaches create additional layers of complexity that traditional tools cannot address.

The Communication Conundrum

One of the most significant blind spots in current explainability approaches involves inter-agent communication. Modern multi-agent systems rely heavily on sophisticated communication protocols that allow agents to share information, negotiate strategies, and coordinate their actions. These communication patterns often determine system behaviour more significantly than individual agent capabilities, yet they remain largely invisible to traditional explanation methods.

Consider a multi-agent system managing a complex supply chain network. Individual agents might be responsible for different aspects of the operation: demand forecasting, inventory management, supplier relations, and logistics coordination. The system's overall performance depends not just on how well each agent performs its individual tasks, but on how effectively they communicate and coordinate with each other. When the system makes a decision to adjust production schedules or reroute shipments, that decision emerges from a complex negotiation process between multiple agents.

Traditional explainability tools can show what information each agent processed and what decisions they made individually, but they cannot adequately represent the communication dynamics that led to the final outcome. They cannot explain why certain agents' opinions carried more weight in the negotiation, how consensus was reached when agents initially disagreed, or what role timing played in the communication process.

The challenge becomes even more complex when considering that communication in multi-agent systems often involves multiple layers and protocols. Agents might engage in direct peer-to-peer communication, participate in broadcast announcements, or communicate through shared data structures. Some communications might be explicit and formal, while others might be implicit and emergent. The meaning and impact of communications can depend heavily on context, timing, and the relationships between communicating agents.

Furthermore, modern multi-agent systems increasingly employ sophisticated communication strategies that go beyond simple information sharing. Agents might engage in strategic communication, selectively sharing or withholding information to achieve their objectives. They might use indirect communication methods, signalling their intentions through their actions rather than explicit messages. Some systems employ auction-based mechanisms where agents compete for resources through bidding processes that combine communication with economic incentives.

These communication complexities create explanatory challenges that extend far beyond the capabilities of current tools. Understanding why a multi-agent system made a particular decision often requires understanding the entire communication history that led to that decision, including failed negotiations, changed strategies, and evolving relationships between agents. Traditional explainability methods, designed for static prediction tasks, lack the conceptual framework to represent these dynamic communication processes.

The situation becomes even more intricate when considering that LLM-based agents can engage in natural language communication that includes nuance, context, and sophisticated reasoning. These agents can develop their own jargon, reference shared experiences, and employ rhetorical strategies that influence other agents' decisions. The richness of this communication makes it impossible to reduce to simple feature attribution scores or importance rankings.

Moreover, communication in multi-agent systems often operates at multiple timescales simultaneously. Some communications might be immediate and tactical, while others might be strategic and long-term. Agents might maintain ongoing relationships that influence their communication patterns, or they might adapt their communication styles based on past interactions. These temporal and relational aspects of communication create additional layers of complexity that traditional explanation methods cannot capture.

Emergent Behaviours and Collective Intelligence

Multi-agent systems frequently exhibit emergent behaviours that arise from the collective interactions of individual agents rather than from any single agent's capabilities. These emergent phenomena represent some of the most powerful aspects of multi-agent systems, enabling them to solve complex problems and adapt to changing conditions in ways that would be impossible for individual agents. However, they also represent the greatest challenge for explainability, as they cannot be understood through traditional decomposition methods.

Emergence in multi-agent systems takes many forms. Simple emergence occurs when the collective behaviour of agents produces outcomes that are qualitatively different from individual agent behaviours but can still be understood by analysing the interactions between agents. Complex emergence, however, involves the spontaneous development of new capabilities, strategies, or organisational structures that cannot be predicted from knowledge of individual agent properties.

Consider a multi-agent system designed to optimise traffic flow in a large city. Individual agents might be responsible for controlling traffic lights at specific intersections, with each agent programmed to minimise delays and maximise throughput at their location. However, when these agents interact through the shared traffic network, they can develop sophisticated coordination strategies that emerge spontaneously from their local interactions. These strategies might involve creating “green waves” that allow vehicles to travel long distances without stopping, or dynamic load balancing that redistributes traffic to avoid congestion.

The remarkable aspect of these emergent strategies is that they often represent solutions that no individual agent was explicitly programmed to discover. They arise from the collective intelligence of the system, emerging through trial and error, adaptation, and learning from the consequences of past actions. Traditional explainability tools cannot adequately explain these emergent solutions because they focus on attributing outcomes to specific inputs or features, while emergent behaviours arise from the dynamic interactions between components rather than from any particular component's properties.

The challenge becomes even more pronounced in multi-agent systems that employ machine learning and adaptation. As agents learn and evolve their strategies over time, they can develop increasingly sophisticated forms of coordination and collaboration. These learned behaviours might be highly effective but also highly complex, involving subtle coordination mechanisms that develop through extended periods of interaction and refinement.

Moreover, emergent behaviours in multi-agent systems can exhibit properties that seem almost paradoxical from the perspective of individual agent analysis. A system designed to maximise individual agent performance might spontaneously develop altruistic behaviours where agents sacrifice their immediate interests for the benefit of the collective. Conversely, systems designed to promote cooperation might develop competitive dynamics that improve overall performance through internal competition.

The emergence of collective intelligence in multi-agent systems often involves the development of implicit knowledge and shared understanding that cannot be easily articulated or explained. Agents might develop intuitive responses to certain situations based on their collective experience, but these responses might not be reducible to explicit rules or logical reasoning. This tacit knowledge represents a form of collective wisdom that emerges from the system's interactions but remains largely invisible to traditional explanation methods.

The Scalability Crisis

As multi-agent systems grow larger and more complex, the limitations of traditional explainability approaches become increasingly severe. Modern applications often involve hundreds or thousands of agents operating simultaneously, creating interaction networks of staggering complexity. The sheer scale of these systems overwhelms human cognitive capacity, regardless of how sophisticated the explanation tools might be.

Consider the challenge of explaining decisions in a large-scale financial trading system where thousands of agents monitor different market signals, execute trades, and adjust strategies based on market conditions and the actions of other agents. Each agent might make dozens of decisions per second, with each decision influenced by information from multiple sources and interactions with numerous other agents. The resulting decision network contains millions of interconnected choices, creating an explanatory challenge that dwarfs the capabilities of current tools.

The scalability problem is not simply a matter of computational resources, although that presents its own challenges. The fundamental issue is that human understanding has inherent limitations that cannot be overcome through better visualisation or more sophisticated analysis tools. There is a cognitive ceiling beyond which additional information becomes counterproductive, overwhelming rather than illuminating human decision-makers.

This scalability crisis has profound implications for the practical deployment of explainable AI in large-scale multi-agent systems. Regulatory requirements for transparency and accountability become increasingly difficult to satisfy as system complexity grows. Stakeholders struggle to assess system behaviour and make informed decisions about deployment and governance. The gap between system capability and human understanding widens, creating risks and uncertainties that may limit the adoption of otherwise beneficial technologies.

The problem is compounded by the fact that large-scale multi-agent systems often operate in real-time environments where decisions must be made quickly and continuously. Unlike batch processing scenarios where explanations can be generated offline and analysed at leisure, real-time systems require explanations that can be generated and understood within tight time constraints. Traditional explainability methods, which often require significant computational resources and human interpretation time, cannot meet these requirements.

Furthermore, the dynamic nature of large-scale multi-agent systems means that explanations quickly become outdated. The system's behaviour and decision-making processes evolve continuously as agents learn, adapt, and respond to changing conditions. Static explanations that describe how decisions were made in the past may have little relevance to current system behaviour, creating a moving target that traditional explanation methods struggle to track.

Regulatory Implications and Compliance Challenges

The inadequacy of current explainability tools in multi-agent contexts creates significant challenges for regulatory compliance and governance. Existing regulations and standards for AI transparency were developed with single-agent systems in mind, assuming that explanations could be generated through feature attribution and model interpretation methods. These frameworks become increasingly problematic when applied to multi-agent systems where decisions emerge from complex interactions rather than individual model predictions.

The European Union's AI Act, for example, requires high-risk AI systems to provide clear and meaningful explanations for their decisions. While this requirement makes perfect sense for individual AI models making specific predictions, it becomes much more complex when applied to multi-agent systems where decisions emerge from collective processes involving multiple autonomous components. The regulation's emphasis on transparency and human oversight assumes that AI decisions can be traced back to identifiable causes and that humans can meaningfully understand and evaluate these explanations.

Similar challenges arise with other regulatory frameworks around the world. The United States' National Institute of Standards and Technology has developed guidelines for AI risk management that emphasise the importance of explainability and transparency. However, these guidelines primarily address single-agent scenarios and provide limited guidance for multi-agent systems where traditional explanation methods fall short.

The compliance challenges extend beyond technical limitations to fundamental questions about responsibility and accountability. When a multi-agent system makes a decision that causes harm or violates regulations, determining responsibility becomes extremely complex. Traditional approaches assume that decisions can be traced back to specific models or components, allowing for clear assignment of liability. However, in multi-agent systems where decisions emerge from collective processes, it becomes much more difficult to identify which agents or components bear responsibility for outcomes.

This ambiguity creates legal and ethical challenges that current regulatory frameworks are ill-equipped to address. If a multi-agent autonomous vehicle system causes an accident, how should liability be distributed among the various agents that contributed to the decision? If a multi-agent financial trading system manipulates markets or creates systemic risks, which components of the system should be held accountable? These questions require new approaches to both technical explainability and legal frameworks that can address the unique characteristics of multi-agent systems.

The Path Forward: Rethinking Transparency

Addressing the limitations of current explainability tools in multi-agent contexts requires fundamental rethinking of what transparency means in complex AI systems. Rather than focusing exclusively on decomposing decisions into individual components, new approaches must embrace the holistic and emergent nature of multi-agent behaviour. This shift requires both technical innovations and conceptual breakthroughs that move beyond the atomistic assumptions underlying current explanation methods.

One promising direction involves developing explanation methods that focus on system-level behaviours rather than individual agent contributions. Instead of asking “Which features influenced this decision?” the focus shifts to questions like “How did the system's collective behaviour lead to this outcome?” and “What patterns of interaction produced this result?” This approach requires new technical frameworks that can capture and represent the dynamic relationships and communication patterns that characterise multi-agent systems.

Another important direction involves temporal explanation methods that can trace the evolution of decisions over time. Multi-agent systems often make decisions through iterative processes where initial proposals are refined through negotiation, feedback, and adaptation. Understanding these processes requires explanation tools that can represent temporal sequences and capture how decisions evolve through multiple rounds of interaction and refinement.

The development of new visualisation and interaction techniques also holds promise for making multi-agent systems more transparent. Traditional explanation methods rely heavily on numerical scores and statistical measures that may not be intuitive for human users. New approaches might employ interactive visualisations that allow users to explore system behaviour at different levels of detail, from high-level collective patterns to specific agent interactions.

Future systems might incorporate agents that can narrate their reasoning processes in real-time, engaging in transparent deliberation where they justify their positions, challenge each other's assumptions, and build consensus through observable dialogue. These explanation interfaces could provide multiple perspectives on the same decision-making process, allowing users to understand both individual agent reasoning and collective system behaviour.

The future might bring embedded explainability systems where agents are designed from the ground up to maintain detailed records of their reasoning processes, communication patterns, and interactions with other agents. These systems could provide rich, contextual explanations that capture not just what decisions were made, but why they were made, how they evolved over time, and what alternatives were considered and rejected.

However, technical innovations alone will not solve the transparency challenge in multi-agent systems. Fundamental changes in how we think about explainability and accountability are also required. This might involve developing new standards and frameworks that recognise the inherent limitations of complete explainability in complex systems while still maintaining appropriate levels of transparency and oversight.

Building Trust Through Transparency

The ultimate goal of explainability in multi-agent systems is not simply to provide technical descriptions of how decisions are made, but to build appropriate levels of trust and understanding that enable effective human-AI collaboration. This requires explanation methods that go beyond technical accuracy to address the human needs for comprehension, confidence, and control.

Building trust in multi-agent systems requires transparency approaches that acknowledge both the capabilities and limitations of these systems. Rather than creating an illusion of complete understanding, effective explanation methods should help users develop appropriate mental models of system behaviour that enable them to make informed decisions about when and how to rely on AI assistance.

This balanced approach to transparency must also address the different needs of various stakeholders. Technical developers need detailed information about system performance and failure modes. Regulators need assurance that systems operate within acceptable bounds and comply with relevant standards. End users need sufficient understanding to make informed decisions about system recommendations. Each stakeholder group requires different types of explanations that address their specific concerns and decision-making needs.

The development of trust-appropriate transparency also requires addressing the temporal aspects of multi-agent systems. Trust is not a static property but evolves over time as users gain experience with system behaviour. Explanation systems must support this learning process by providing feedback about system performance, highlighting changes in behaviour, and helping users calibrate their trust based on actual system capabilities.

Furthermore, building trust requires transparency about uncertainty and limitations. Multi-agent systems, like all AI systems, have boundaries to their capabilities and situations where their performance may degrade. Effective explanation systems should help users understand these limitations and provide appropriate warnings when systems are operating outside their reliable performance envelope.

The challenge of building trust through transparency in multi-agent systems ultimately requires recognising that perfect explainability may not be achievable or even necessary. The goal should be developing explanation methods that provide sufficient transparency to enable appropriate trust and effective collaboration, while acknowledging the inherent complexity and emergent nature of these systems.

Trust-building also requires addressing the social and cultural aspects of human-AI interaction. Different users may have different expectations for transparency, different tolerance for uncertainty, and different mental models of how AI systems should behave. Effective explanation systems must be flexible enough to accommodate these differences while still providing consistent and reliable information about system behaviour.

The development of trust in multi-agent systems may also require new forms of human-AI interaction that go beyond traditional explanation interfaces. This might involve creating opportunities for humans to observe system behaviour over time, to interact with individual agents, or to participate in the decision-making process in ways that provide insight into system reasoning. These interactive approaches could help build trust through experience and familiarity rather than through formal explanations alone.

As multi-agent AI systems become increasingly prevalent in critical applications, the need for new approaches to transparency becomes ever more urgent. The current generation of explanation tools, designed for simpler single-agent scenarios, cannot meet the challenges posed by collective intelligence and emergent behaviour. Moving forward requires not just technical innovation but fundamental rethinking of what transparency means in an age of artificial collective intelligence.

The stakes are high, but so are the potential rewards for getting this right. The future of AI transparency lies not in forcing multi-agent systems into the explanatory frameworks designed for their simpler predecessors, but in developing new approaches that embrace the complexity and emergence that make these systems so powerful. This transformation will require unprecedented collaboration between researchers, regulators, and practitioners, but it is essential for realising the full potential of multi-agent AI while maintaining the trust and understanding necessary for responsible deployment.

The challenge ahead is not merely technical but fundamentally human: how do we maintain agency and understanding in a world where intelligence itself becomes collective, distributed, and emergent? The answer lies not in demanding that artificial hive minds think like individual humans, but in developing new forms of transparency that honour the nature of collective intelligence while preserving human oversight and control.

Because in the age of collective intelligence, the true black box isn't the individual agent—it's our unwillingness to reimagine how intelligence itself can be understood.
