What is the difference between a single-agent and multi-agent AI system?

A single agent uses only one agent to manage all its tasks, use tools, and make decisions. A multi-agent system splits the work among other agents and finishes the tasks. The use of this system is based on the workflow, complexity and context involved. A business can choose a system according to its needs.

Is multi-agent AI always more accurate than a single agent?

Using more agents does not mean that they improve accuracy. A multi-agent method is useful when different agents bring separate skills and review each other's work. Also remember that it can create more handoffs and costs. A team should test the accuracy on the workflow with single and multi-agent before finalizing one.

How much more does a multi-agent system cost to run?

Usually, the cost of a multi-agent system is more than using a single one because they involve more model calls, uses more tokens, coordinates with other agents and uses more infrastructure. The exact cost is difficult to say as it depends on the design. Always compare the cost with the workflow, not with the single agent.

When should an enterprise move from a single agent to multiple agents?

Moving to multiple agents should not be a trend or to feel like you have the most advanced system. The main reason for moving is that the present agent cannot handle everything well now. Some of the other reasons include parallel tasks, separate roles, contextual issues, and the need for a separate agent for review. If a single agent can do a better job with scripts and tools, keep the simple one.

Can single and multi-agent AI systems work together?

Yes, they work. This is called a hybrid system where one main agent handles most of the workflow and calls specialist agents for the special cases where there is complexity. A system like this is useful for teams without adding unnecessary complexity to every step.
