Welcome to the exciting world of multi-agents! These LLM marvels are revolutionizing productivity by working alongside humans to tackle complex problems. From drafting reports to debugging code and managing data centers, the ability to build AI agents that collaborate effectively represents the future of the AI workforce.
How do you measure the success of multi-agent systems? Evaluating MAS (multi-agent systems) is like scoring a relay race—not just the individual racers, but also how smoothly the baton is passed between them.
But before more on that…
What are Multi-Agent Systems?
A multi-agent system contains multiple AI agents working together in a shared environment to achieve an overarching goal. This goal may or may not require each agent to contribute.
Why not just pass along different system prompts to the same agent? Multi-agent systems allow multiple agents to work independently, perceiving and making decisions that lead to the task more systematically and efficiently.
What are Multi-Agent Eval Systems?
Multi-agent evaluation systems can be understood as tools, wrappers, or services used to assess the behavior of agentic systems.
These systems are not limited to quantitative evaluations like latency or token usage. Modern evaluation methods provide deeper insights into agentic behaviors through metrics that cover more qualitative areas such as coherence and semantic similarity to source content.
The Fun (and Frustration) of Evaluating MAS
Evaluating multi-agent systems (MAS) requires asking the right questions at every step of the pipeline. These aspects can help you reconsider or refine your system’s agentic design:
1. Cooperation and Coordination
Are your agents playing nice with each other, or are they disingenuous and chaotic? For instance, in a data bank, agents need to collaborate to avoid conflicts, like overwriting dynamic files that another agent is actively using.
2. Tool and Resource Utilization
How well do the agents use the tools at their disposal? If you are deploying a MAS for data analysis, are the agents dividing the workload efficiently or is there duplication of effort?
3. Scalability
Adding more agents can make or break a system. Does performance improve with scale, or do the agents start stepping on each other’s shoes? If the agents overlap too much, you'll be eating away precious compute resources.
How to Build Multi-Agent Evaluation Systems?
A few tasks need to be achieved to create an effective evaluation framework for your multi-agent system. Here’s how to structure your pipeline:
- Agent Interaction Logs: Track every decision, action, and communication for analysis.
- Evaluation Metrics: Define metrics and benchmarks for agentic interactions.
- Evaluation Framework: Choose the right framework to start implementing the evaluation using.
1. Agent Interaction Logs
Agent-level accountability needs to be maintained for the general task of evaluating multi-agent systems. Generating logs for interactions that show each agent's reasoning, actions, and consequences promotes robust systems.
Now such logs can contain timestamps, tool calls, generated results, or internal conversations. Here is a sample log of a conversation from an agent deployed using Botpress.
2. Evaluation Metrics
Evaluating MAS comes down to the right metrics, and practical tools to measure performance. Once the logs are ready, it’s time to decide what to evaluate. Here are the key metrics to assess your MAS:
When evaluating such systems, it’s essential to focus on metrics that reflect their collaboration, tool usage, and output quality.
3. Evaluation Framework
When choosing the framework to source and compile the metrics, you can easily find a plethora of resources in the form of open-source libraries. Let us take a look at DeepEval, TruLens, RAGAs, and DeepCheck, some of the top frameworks that you can use for evaluation:
Once your evaluation framework is in place, it’s time to focus on action. The metrics and insights you gather should guide how you refine your multi-agent systems:
- Tweak Collaboration Protocols: Use metrics to adjust how agents interact and share tasks.
- Enhance Resource Allocation: Data from evaluation frameworks can highlight inefficiencies in tool usage or compute resource distribution.
- Address Bias Proactively: Regular checks with the evaluation frameworks mentioned ensure your MAS outputs are fair and equitable.
Elevate your Automation Pipeline with Multi-Agents
Multi-agent evaluation systems are the cornerstone of creating efficient, reliable, and adaptive AI agents. Whether you’re optimizing workflows, enhancing decision-making, or scaling complex tasks, robust evaluation frameworks ensure your systems perform at their best.
