What is Multi Agent System in AI?

A multi-agent system (MAS) consists of multiple independent AI agents or software agents that interact with each other. Multiple agents can be software programs, advanced language models, or physical robots. These independent agents can be designed as complex agents to handle complicated tasks within the system. A MAS addresses complex tasks by distributing them among specialized agents that work together, coordinate, or compete to achieve individual or shared goals.

Why Multi-Agent Systems Matter?

We have recently understood the approach to how to create AI agents. Which clearly makes sense. After all, it is all about getting things done even when you are focusing on something essential.

However, as tasks become more complex and the number of tools expands over time, single AI agents find it challenging to handle them. And the effects would be completely apparent when agents start misbehaving like

• Getting confused about which tools to use or when.
• Large context windows contain so many tools to handle.
• Begins producing incorrect or suboptimal results because of broad responsibilities.

That is where multi-agent systems help. In a multi-agent system, each agent specializes in specific tasks and tools. This enhances solution quality and clarity with better management of complicated tasks.

What are the Components of a Multi Agent System?

The multi-agent systems consist of several components. However, the main components of a Multi-Agent System are

Agents

Agents are independent entities with their own goals. They make decisions within a shared environment to achieve their personal or common objectives. Each artificial intelligence agent has some autonomy, can observe its surroundings, make choices based on its goals, and take action. When these agents collaborate, they create autonomous systems that need minimal human intervention.

Environment

The environment is where interactions happen. It is the shared space where agentic AI systems work, sense, and connect. The environment sets limits and offers resources.

Interactions

Interactions refer to how agents communicate and work together. They help AI agents share information and knowledge. Agents collaborating with each other enable them to achieve common goals more effectively by combining their capabilities and resources.

In the Interactions, agent behaviors and collective behavior emerge from the interactions between agents. Message passing is a common method for agents to communicate and coordinate their actions.

Orchestration

Organization involves creating a clear plan that breaks a complex task into smaller parts and assigning them to skilled individuals. This plan can be centralized, with one leader overseeing all. Or decentralized, where different teams manage their own sections.

Architecture of a Multi-Agent System

Multi-agent architectures define how agents are organized and interact within a system. The choice of architecture has a significant impact on how agent systems perform specific tasks and respond to challenges. There are several common types of multi-agent architectures, each suited to different scenarios.

In hierarchical architectures, agents are arranged in a tree-like structure. This architecture features higher-level agents that oversee and coordinate the actions of other agents.

This structure is specifically effective for tasks where centralized oversight can help maintain efficiency and consistency across the entire system.

Decentralized systems have a simple structure where each agent works independently. This setup is suitable for situations like responding to disasters. Decentralized agent systems excel in dynamic environments where flexibility and speed are essential.

Hybrid architectures combine features of both hierarchical and decentralized models. This helps organizations customize their multi-agent systems to meet the specific needs of different tasks.

By selecting the right multi agent architecture, businesses can ensure their agents work together effectively. However, selecting the right one requires professional expertise. Our AI Consulting and Strategy experts can help you identify the right one for your business use case. But before that, let us see how these multi agent systems work.

How do Multi Agent Systems Work?

A multi-agent system solves complex problems by following these steps:

Task Decomposition

The system starts with a broad goal and divides it into smaller and manageable sub-tasks.

Assigning Agents

Each sub-task is assigned to a specialized agent. For example, a "researcher" agent gathers information, while a "writer" agent creates content.

Collaborative Execution

Agents work on their tasks, communicating and collaborating as needed. They may do this one after the other or all at once to make the process faster. Running multi-agents in parallel enables the system to efficiently handle complex workflows.

Coordinated Problem-Solving

The work done by all agents combines to create the overall solution. The system might collect all outputs or have a main “supervisor” agent review and merge the results.

Learning and Adapting

Agents improve through experience and interactions. Building AI agents with advanced learning abilities allows for ongoing enhancement in problem-solving.

Advantages of Multi Agents Systems

Multi-agent systems offer many benefits, including coordinated actions and interactions that enhance performance, adaptability, and scalability. These advantages are not constrained to a single industry. Rather, they are expanding to almost every industry and role. Let us check some of them.

Specialization

In multi-agent systems, tasks are broken down into smaller parts. These parts are assigned to agents based on their skills. Each independent agent uses its strengths to complete tasks and share information with others. This way, multiple agents provide better results, as agents can specialize in what they do best.

Modularity

Multi-agent systems are designed to be modular. This means that different tasks can be given to different agents, and they work independently. Modularity makes development, testing, and maintenance easier since new agents can be added without changing the overall system. Also, any existing agents can be replaced anytime.

Robustness

The main advantage of a MAS is its strength, which comes from being decentralized. So, if one agent fails or has a problem, the other agents keep working and can take over the tasks of the failed one. This allows the system to run effectively.

Collaborative Learning

In multi-agent systems, separate agents work together to find solutions. They share ideas, provide feedback, and help each other understand varied issues. Such teamwork is helpful when handling complex issues.

Parallelism

MAS comes with a built-in ability for parallel processing. Here, multiple agents work simultaneously on different parts of a similar problem. This teamwork greatly improves efficiency and allows the system to complete tasks faster than a single agent could.

Real-time Response

MAS works well for tasks that require quick responses. The agents can act individually and simultaneously. This simultaneous execution allows them to quickly process information and respond to rapidly changing situations. Such a quick response makes MAS suitable for applications like self-driving cars and emergency response systems.

Scalability

MAS can solve large issues by distributing the work among multiple agents. Each intelligent agent focuses on a specific part of the problem or task. So, businesses can expand their multi-agent system anytime by adding more agents.

Better Decision Making

Multiple-agent systems can improve decision-making by gathering insights from different agents. Each agent offers a unique perspective and expertise. This shared knowledge helps agents make better-informed decisions.

Applications of Multi Agents

MAS are increasingly used for complex problem solving in collaboration with human teams across various industries. Academic research in MAS has led to practical applications in real-world business scenarios. The key applications of the multiple AI agent systems include,

Healthcare

Multi agents work together to monitor patient data, schedule appointments, and support clinical decisions. They combine records from different sources, which helps provide real-time care. AI in the healthcare industry can provide improved and personalized treatment plans quickly.

Education

AI agents personalize learning by tailoring content to students' preferences and progress. They serve as tutors in subjects like math, science, and language. In group settings, these multi-agents provide feedback, monitor progress, and create a customized learning experience.

Customer Service

Multi-Agent Agentic AI improves support by using specialized agents to handle customer queries. These agents work together to give quick answers and can easily connect to human agents when necessary. This ensures efficient and personalized service.

In supply chain management, MAS are used to coordinate inventory, shipping, and delivery. This ensures that products reach customers efficiently and cost-effectively.

In transportation systems, multi-agent systems help optimize traffic flow and reduce congestion by allowing AI agents to manage signals, reroute vehicles, and respond to accidents in real time. This leads to smoother commutes and improved safety for everyone on the road.

Smart cities are also using MAS to manage energy consumption, waste collection, and public safety. By using AI agents across the city, local governments can create environments that are more efficient, sustainable, and enjoyable to live in.

Challenges of Implementing Multi Agent Systems

Companies that want to use multi-agents face challenges beyond just technicalities. Implementing MAS can improve efficiency and flexibility in businesses, but it comes with certain challenges that need to be addressed.

1. Complex Coordination

Managing multi agent communication and synchronization can lead to operational overhead, especially in enterprise-scale systems. Coordination complexity is a key challenge in developing effective MAS, as agents must coordinate and negotiate with each other to ensure proper collaboration and system functionality.

2. Integration with Legacy Infrastructure

Many companies rely on outdated and diverse technology. Ensuring that MAS works well with current platforms and tools requires good interoperability.

3. Scalability with Governance

Scaling a MAS involves more than just adding more agents. It also needs strong governance frameworks to ensure efficiency and keep the system aligned with the enterprise goals.

4. Conflict Management

Agents can have different goals and needs for resources. So, companies need clear policies for negotiating, setting priorities, and resolving conflicts.

5. Security and Compliance Risks

Distributed systems have security risks, like unauthorized access or harmful agents. At such stage, following rules like GDPR and CCPA makes things more complicated.

6. Specialized Expertise and Cost

Developing and maintaining MAS requires niche expertise in AI and distributed systems. However, new no-code frameworks now allow organizations to build their own multi agent systems and agentic systems with less technical overhead, making it easier for domain experts to create custom solutions without deep engineering expertise.

7. Monitoring and Transparency

Tracking the performance and decision-making of multiple autonomous agents can be challenging.

Difference Between Single vs Multi Agent Systems

When it comes to building intelligent solutions, the choice between a single-agent system and a multi-agent system can significantly impact performance, scalability, and adaptability. While both agents work to resolve issues and take action, their approaches and capabilities also differ.

A single-agent system works independently. It focuses on a defined task or environment. Single AI agents are straightforward, predictable, and easy to manage. But they are limited in handling highly dynamic or distributed scenarios.
