Overview

• Researchers are working on developing powerful general-purpose agents that use Foundation Models as modules.
• However, hand-designed solutions are often replaced by learned solutions in machine learning.
• A new research area called Automated Design of Agentic Systems (ADAS) aims to automatically create powerful agentic system designs, including inventing novel building blocks or combining them in new ways.
• An unexplored approach within ADAS is to have agents defined in code, with a meta agent automatically discovering new agents by programming better ones.
• Since programming languages are Turing Complete, this approach theoretically enables learning any possible agentic system, including novel prompts, tool use, control flows, and combinations.

Plain English Explanation

Researchers are working on building powerful AI systems that can perform a wide variety of tasks, using large language models called Foundation Models as building blocks. However, the history of machine learning shows that hand-designed solutions often get replaced by solutions that the system learns on its own.

To address this, the researchers propose a new research direction called Automated Design of Agentic Systems (ADAS). The goal of ADAS is to automatically create powerful AI systems, including discovering new types of building blocks or combining existing ones in novel ways.

One promising but unexplored approach within ADAS is to define the AI agents in computer code, and then have a "meta agent" automatically discover new and better agents by programming them in code. This is possible because programming languages are Turing complete, meaning they can represent any possible computation.

By taking this code-based approach, the researchers believe they can automatically invent AI agents with completely new capabilities, such as using tools in unique ways, following complex control flows, or combining multiple skills in novel ways. The key idea is to let the meta agent iteratively program better and better agents, rather than hand-designing them.

Technical Explanation

The paper introduces a new research direction called Automated Design of Agentic Systems (ADAS), which aims to automatically create powerful agentic system designs. This includes inventing novel building blocks for agents, as well as combining existing components in new ways.

The researchers demonstrate a promising but unexplored approach within ADAS, where agents are defined in code and a "meta agent" automatically discovers new agents by programming ever-better ones. Since programming languages are Turing complete, this allows the meta agent to theoretically learn any possible agentic system, including novel prompts, tool use, control flows, and combinations thereof.

The paper presents a simple algorithm called Meta Agent Search to explore this idea. The meta agent iteratively programs new agents based on an ever-growing archive of previous discoveries. Through extensive experiments across domains like coding, science, and math, the researchers show that Meta Agent Search can progressively invent agents with novel designs that greatly outperform state-of-the-art hand-designed agents.

Importantly, the researchers find that the agents discovered by Meta Agent Search maintain superior performance even when transferred across domains and models, demonstrating their robustness and generality.

Critical Analysis

The paper presents a promising new research direction, but there are some caveats and limitations to consider.

While the code-based approach theoretically enables learning any possible agentic system, the researchers acknowledge that safely developing such a system is a significant challenge. Careful consideration must be given to ensure the meta agent does not invent agents with unintended or harmful behaviors.

Additionally, the experiments in the paper are still relatively limited in scope, focusing on a few specific domains. Further research is needed to fully evaluate the performance and generalization capabilities of the automatically discovered agents across a wider range of tasks and environments.

The paper also does not address potential issues around interpretability and transparency of the automatically generated agents. As these systems become more complex, it may become increasingly difficult to understand and explain their inner workings, which could limit their real-world applicability.

Conclusion

This paper proposes an exciting new research direction called Automated Design of Agentic Systems (ADAS), which aims to automatically create powerful AI agents by having a "meta agent" program ever-better agents in code. The researchers demonstrate a promising approach within ADAS, showing that their Meta Agent Search algorithm can discover agents with novel designs that outperform state-of-the-art hand-designed agents.

If developed safely, this research could lead to the creation of highly capable and versatile AI systems that can adapt to a wide range of tasks and environments. However, significant challenges remain in terms of ensuring the safety and interpretability of these automatically generated agents. Continued research in this area could have important implications for the future of artificial intelligence and its potential to benefit humanity.
