AI Agents: Digital Workforce, Reimagined

Over the last twenty-four months, Generative Artificial Intelligence (Gen AI) has stunned and excited the world with its potential for reshaping how knowledge work gets done in industries and business functions across the economy.

Across functions such as sales, marketing, customer operations, and software development, it is poised to transform roles and boost performance. In the process, it has the potential to unlock trillions of dollars in value across sectors from banking to life sciences.

The next big thing in the world of Gen AI is the emergence of AI agents signifying a paradigm shift in artificial intelligence (AI), propelling us from passive, task-oriented models to dynamic, interactive systems capable of independent action.

Earlier this year, OpenAI CEO Sam Altman described agents as “AI’s killer function”. This paper provides business leaders with a concise yet comprehensive overview of AI agents, their potential impact on industries, and the key considerations for their successful implementation.

What are AI Agents?

‍

AI agents are intelligent, autonomous, human-like systems that leverage the power of Gen AI along with other technologies to understand their environment, make decisions, execute actions, and learn continuously to achieve a specific goal.

As a technology, Gen AI has already proven its ability to accomplish human-like tasks such as writing a thought leadership essay on a topic. However, this involves a single prompt with a direct answer that may have some errors.

One reason why AI agents are the next big thing in Gen AI is their ability to enable “Agentic Workflows”. These are scenarios where the AI interacts with the prompt in stages, “thinks” about its work output, and refines it to provide significantly better results.

Consider the earlier example where the desired goal is a thought leadership essay on a topic. This would involve building a specialized AI Agent that can create an outline of the essay, conduct research (by collaborating with another agent), prepare an initial draft, review it (again by collaborating with another agent), and prepare a final version. This leads to a much better output as compared to the earlier “non-agentic” workflow.

‍

The design principles that make Agentic Workflows possible involve four simple steps:

‍

Reflection: Allowing the AI to evaluate its own work.
Tool usage: Enabling the AI to use external tools (such as APIs or other software) to execute actions.
Planning: Implementing algorithms to enable the AI to break down complex tasks into simpler ones, and adapt to changing environments.
Multi-agent collaboration: Enabling multiple agents, each with a different specialization, to collaborate in order to achieve a common goal.

‍

Another development in this rapidly advancing space is Agentic Frameworks. These provide a technology foundation, development tools, and accelerators for building AI agents.

Some examples of Agentic Frameworks include ReAct, Autogen, LangChain, TaskWeaver, Vertex AI Agent Builder, Agent Transformer, Mind Agent, and LM-Nav.

While each may have its strengths and weaknesses, a detailed explanation of these is beyond the scope of this document.

What are the various types of AI Agents?

‍

AI Agents can be of various types. Some of them are illustrated below.

What are the various types of AI Agents?‍

‍

Goal-Based Agents: These are focused on reasoning and deciding on a defined goal.
Utility Agents: These can handle situations with multiple conflicting goals, to maximize their utility.
Learning Agents: These look to constantly improve their performance over time through reinforcement learning.
Generalization Agents: These can adapt to new situations and apply their knowledge to previously unseen situations.
Personality Agents: These incorporate personality traits, including emotions and character, to appear more human-like.
Collaboration Agents: This can work with other agents in multi-agent workflows to handle complex problems.
Action Agents: These execute actions in a simulated or real environment
Interactive Agents: These focus on user interactions and engagement (such as chatbots).

‍

Intention Agents: These specialize in planning and decision-making, delegating tasks to other specialized agents.
Knowledge Agents: These specialize in accessing and retrieving information from various knowledge sources.
Multimodal Agents: This can integrate data from multiple sources and make more informed decisions.

How are AI Agents different from automation “bots” that use AI?

‍

Automation bots that use AI have been around for quite some time now. Their focus has primarily been on the automation of low-level, repetitive, and mundane tasks leveraging technologies such as Robotics Process Automation (RPA) and Optical Character Recognition (OCR). They have also leveraged traditional AI technologies to move towards “cognitive automation” such as intelligent document processing.

AI Agents however are at a completely different level of technology evolution, with the ability to autonomously plan and execute tasks, adapt to changing circumstances, maintain memory, learn from past transactions and interactions, and use various tools to achieve a goal.

In contrast, automation bots typically follow pre-defined rules and lack the capacity for independent decision-making and problem-solving that characterizes AI agents.

‍

What are the key components of an AI agent?

Conceptually speaking, AI Agents are not new. However, they have become a reality over the last 18-24 months primarily because of the breakthroughs with Generative AI and Foundation Models which are at the heart of AI agents.

While the initial versions of AI agents relied on Large Language Models for language input and output, newer versions are quickly adapting to Multimodal Models with input and output capabilities across language, audio, image, and video. Foundation models provide the core reasoning, comprehension, and decision-making abilities of AI agents.

Apart from foundation models, AI agents may use a variety of tools to interact with the digital and physical world. These could include application APIs, web search and crawlers, databases, and even other AI models.

AI Agents also maintain a memory or state, allowing them to remember past interactions, learn from experiences, and make informed decisions based on context.

Another key component of an AI Agent is the Reasoning Loop, which allows agents to analyze information, break down complex tasks into smaller steps, and determine the optimal sequence of actions to achieve their goal.

Recent research is exploring the use of Large Action Models, - specialized AI models to handle complex and multi-step tasks - to enhance the effectiveness of AI Agents.

Risks and challenges with AI Agents

‍

With great potential comes great risk. Any business leader must be aware of the risks and challenges associated with AI Agents. A few of these are illustrated below.

‍

‍

Errors: It is well known that Gen AI foundation models can make mistakes (hallucinations, for example). One way to address this so far has been using a “human in the loop” design approach. However, AI Agents are autonomous by design: you either remove the humans from the loop completely or minimize their involvement and increase the autonomy provided to agents. This increases the risk of the agent making a mistake in an interpretation, decision, or action, and such errors could be very expensive.
Bias and fairness: AI agents trained on biased data can perpetuate existing biases and lead to unfair or discriminatory outcomes. It's crucial to ensure data diversity and fairness in AI agent training and deployment.
Job displacement: The automation capabilities of AI agents raise concerns about potential job displacement. It's crucial to address these concerns through workforce retraining and the creation of new job opportunities in the AI economy.
Privacy and security: AI agents often handle sensitive data. Implementing robust security measures and ensuring compliance with data privacy regulations is crucial to maintaining customer trust.
Explainability and transparency: The decision-making processes of AI agents can be complex and opaque. It's crucial to develop mechanisms for explaining and auditing AI agent decisions to ensure transparency and accountability.
Loss of control: Since AI Agents are autonomous by design, there is a risk of them going out of our control. For example, AI Agents have only one goal: to achieve their goal. And they could adopt any means necessary to do this, including potentially performing actions that could be unethical or against existing legal or compliance requirements. Business leaders need to be aware of this and design preventative measures accordingly.
