**Beyond Assistants & LLMs: The Rise of Agentic AI and Large Action Models**

The hype around language models like ChatGPT has been explosive - the real "Breaking Bad" moment of AI. But just like Walter White realized there was more to the game, the true players know language is just the start. So if you're ready to call in the heavy hitters that can actually get stuff done, you better call Saul... I mean your Agent ;)

Well, enough with this far-fetched pun. As my fellow compatriot Yan LeCun, Chief AI Scientist at Meta, recently affirmed at the Vivatech conference: generative AI has only 5 years left to live. Large Language Models are not the future of artificial intelligence because they lack four key characteristics: understanding the real world, having persistent memory, reasoning, and planning ability.

This article introduces AI Agents, how they work, how they differ from Chatbots and Copilots, and how Agentic AI represent the next step after the current hype around LLMs. In the world beyond the linguistic fireworks, a new breed of AI systems is emerging - one that doesn't just process language but perceives, reasons, and acts upon the world around them.

## What are AI Agents?
At their core, AI Agents are software systems that can perceive their environment, process that information, and take actions to achieve specific goals. Unlike traditional programs that simply follow a predefined set of rules, agents can make decisions and adapt their behavior based on the current state of their environment and their objectives.

AI Agents are often described as having properties like autonomy, reactivity, pro-activeness, and goal-orientedness. They can operate without constant human supervision, respond to changes in their environment, take the initiative to achieve their goals, and persistently work towards those objectives over extended periods. They interact with their environment through various modalities, such as vision, robotics, and control systems, in addition to natural language. 

While ChatBots and language models are typically focused on generating human-like responses, Agents are designed to achieve specific goals efficiently, even if their actions may not always appear "human-like."

## How AI Agents Work

At the heart of an AI agent lies a decision-making process that determines how the agent should act in a given situation. This process typically involves several key components:

1. **Perception**: Agents receive inputs from their environment through sensors, such as cameras, microphones, or other data sources. This sensory information is processed and used to build an internal representation of the current state of the environment.

2. **State Estimation**: Based on the perceived inputs and the agent's prior knowledge, it estimates the actual state of the environment. This step often involves handling uncertainties, noise, and incomplete information.

3. **Goal Setting**: Agents have predefined goals or objectives they are trying to achieve. These goals can be static or dynamically adjusted based on the agent's current state and the environment.

4. **Planning**: Given the current state and the desired goal, the agent generates a plan or a sequence of actions that it believes will lead to achieving the goal. This may involve techniques like search algorithms, decision trees, or reinforcement learning.

5. **Action Selection**: The agent chooses the best action to take based on its plan and the current state. This decision-making process may involve evaluating the potential rewards and risks associated with each action.

6. **Action Execution**: The chosen action is then executed, potentially changing the state of the environment.

This cycle of perception, state estimation, planning, and action execution repeats continuously, allowing the agent to adapt its behavior based on the changing environment and progress towards its goals.

One of the key challenges in developing AI agents is teaching them how to make good decisions and take effective actions in complex, uncertain environments. This is where techniques like reinforcement learning come into play.

Reinforcement learning algorithms allow agents to learn from experience by taking actions in an environment and receiving rewards or penalties based on the outcomes of those actions. Over many iterations, the agent learns to associate certain actions with positive or negative outcomes, gradually refining its decision-making strategy to maximize long-term rewards.

Large Action Models (LAMs) are a specific type of AI agent that leverages deep reinforcement learning techniques to learn how to perform complex, multi-step tasks by taking sequences of actions over extended time horizons. These models can learn intricate behaviors in simulated environments before transferring that knowledge to real-world robotics or control systems.

## Agents vs. ChatBots and Copilots

While Chatbots, Copilots, and Agents all fall under the umbrella of Artificial Intelligence, they differ significantly in their design, capabilities, and intended use cases. Understanding these differences is crucial to appreciate the potential of Agentic AI and Large Action Models (LAMs).

*ChatBots*
ChatBots are designed primarily for natural language interaction with humans. Their main purpose is to understand and respond to user queries or commands in a conversational manner. They are typically built using Natural Language Processing (NLP) techniques, such as intent recognition, entity extraction, and language generation.

While ChatBots can be quite sophisticated in their language abilities, they are generally limited to the domain of text-based communication. They cannot directly perceive or interact with the physical world beyond the text interface.

*Copilots*
Copilots, or Digital Assistants, are a step up from ChatBots in terms of functionality. They are designed to assist users with a wider range of tasks, such as scheduling appointments, setting reminders, and retrieving information from various sources.

Copilots often integrate with other software applications and services, allowing them to perform actions like sending emails, creating calendar events, or controlling smart home devices. However, like ChatBots, their primary mode of interaction is still through natural language.

*AI Agents*
Unlike ChatBots and Copilots, Agents are not limited to natural language interaction. They are designed to perceive and interact with their environment through various modalities, such as vision, robotics, and control systems. They can navigate physical spaces, manipulate objects, and even control complex systems like vehicles or industrial machinery.

Moreover, agents are goal-oriented, meaning they are designed to achieve specific objectives rather than just responding to user queries or commands. They can plan and execute sequences of actions over extended periods to reach their goals, adapting their behavior based on the changing environment.

Agentic AI and Large Action Models (LAMs) take this concept of goal-oriented agents even further. LAMs are a class of AI agents that leverage deep reinforcement learning techniques to learn how to perform complex, multi-step tasks by taking sequences of actions over long time horizons.

These models can learn intricate behaviors in simulated environments and then transfer that knowledge to real-world robotics or control systems, enabling them to tackle a wide range of challenges, from playing complex games to controlling autonomous vehicles or industrial robots.

## The Potential of Agentic AI and Large Action Models

Agentic AI and LAMs (re)opens up a vast array of potential applications and possibilities.

*Robotics and Automation*
One of the most obvious applications is in the field of robotics and automation. These models could enable robots to learn and perform intricate tasks autonomously, from assembling products in factories to exploring remote or hazardous environments. By training in simulated environments, LAMs could acquire the necessary skills before being deployed in the real world, reducing the need for extensive manual programming and improving safety.

*Autonomous Vehicles*
Self-driving cars are often cited as a prime example of the potential of Agentic AI. LAMs could be trained in highly realistic simulations to navigate complex urban environments, anticipate and respond to unpredictable situations, and make split-second decisions to ensure the safety of passengers and pedestrians. This could accelerate the development and deployment of fully autonomous vehicles. For instance, companies like Tesla and Waymo are already exploring the integration of AI agents that can manage these sophisticated tasks independently.

*Gaming and Virtual Environments*
LAMs have already shown impressive results in mastering complex games and virtual environments, such as playing strategy games at superhuman levels or navigating 3D worlds. As these models continue to advance, they could lead to more intelligent and adaptive non-player characters (NPCs) in video games, as well as more realistic and engaging virtual simulations for training purposes.

*Healthcare and Scientific Research*
Agentic AI and LAMs could also have a significant impact on fields like healthcare and scientific research. These models could be trained to analyze complex medical data, simulate biological processes, or even control robotic surgical systems, potentially leading to more accurate diagnoses, personalized personalized treatments, and advanced medical procedures.

In scientific research, LAMs could be used to explore and analyze vast amounts of data, identify patterns and relationships, and even design and conduct virtual experiments, accelerating the pace of scientific discovery and innovation.
