Gen AI Agents 101

The #1 reason why LLMs fail to give people the output they are looking for is that the task is usually too complex.

People ask too much in a single prompt to (typically) a base chat model.

I want to teach you why this approach does not work with the LLM chats of today and why agents are the solution and how they work.

Current chat models lack the skill required to reason about tasks that are too complex and require many steps.

Overwhelming Base LLMs

The allure of asking complex questions to chat models is understandable. After all, we're promised AI that can converse like humans. But this approach is fundamentally flawed, and here's why:

Cognitive Overload: Base LLMs, despite their vast knowledge, lack the cognitive architecture to juggle multiple concepts simultaneously. When bombarded with a complex query, they often fixate on one aspect while neglecting others, leading to incomplete or irrelevant responses.

Lack of Strategic Thinking: These models don't possess the ability to break down complex tasks into manageable steps. They can't prioritize subtasks or create a logical sequence of actions, resulting in haphazard and often nonsensical outputs when faced with multi-faceted problems.

Context Limitations: While LLMs have impressive context windows, they still struggle with maintaining coherence across long, intricate prompts. This leads to responses that may address parts of your query but miss the overall objective.

The consequences of relying on this flawed approach are far-reaching. Businesses make decisions based on incomplete analysis. Developers waste hours trying to coax coherent solutions from resistant models. And users, frustrated by inconsistent results, lose faith in AI's potential to truly augment human intelligence.

As we continue to push the boundaries of what we ask these models to do, it's clear that a new paradigm is needed – one that can handle the intricacy and nuance of real-world problems without succumbing to the limitations of base LLMs. But what does this new paradigm look like?

Enter Gen AI Agents

As the limitations of base LLMs become increasingly apparent, a new paradigm emerges to address the complexity challenge, namely, Gen AI Agents.

Gen AI Agents are not merely enhanced language models, they're intelligent ecosystems built to parse, plan, and execute complex tasks with a level of competence previously unseen in AI. By combining the linguistic prowess of LLMs with structured decision-making capabilities, these agents can break down complex queries into manageable steps, reason about each component, and synthesize coherent solutions.

3 key advantages of Gen AI Agents:

1. Task Decomposition: Unlike base LLMs, agents can dissect complex problems into smaller, more manageable subtasks. This allows for a systematic approach to problem-solving, mirroring human cognitive processes.

2. Strategic Planning: Agents possess the ability to create and follow logical sequences of actions, prioritizing steps and adjusting strategies as needed.

3. Memory and Context Management: With advanced memory systems, agents can maintain context over extended interactions, ensuring coherence and continuity in complex, multi-stage tasks.

As we delve deeper into how these agents work, it becomes clear that they represent not just an incremental improvement, but a fundamental shift in how we interact with and leverage artificial intelligence. But how exactly do these sophisticated systems operate?

How Gen AI Agents Work: A Simplified Overview

Gen AI Agents represent a sophisticated orchestration of multiple AI components working in harmony. At the core of everything lies the LLM but what other components are needed to make this work, lets zoom in on the main parts:

1. LLM - The brain of the agent, processing language inputs and generating outputs.

2. Task Planner - Breaks complex tasks into smaller, manageable steps.

3. Memory System - Stores and retrieves relevant information for ongoing and future tasks.

4. Tool Kit - A set of integrated tools and APIs the agent can use to perform actions.

5. Decision Engine - Evaluates options and chooses the best course of action based on available data.

6. (Advanced) Execution Monitor - Oversees the task progress, adjusting the plan as needed.

7. Output Refiner - Polishes the final result for coherence and relevance.

8. (Advanced) Learning Module - Improves the agent's performance over time based on past experiences.

These components work together to enable the agent to understand complex requests, create strategic plans, gather necessary information, make informed decisions, and produce refined outputs. This integrated approach allows Gen AI Agents to tackle intricate, multi-step problems that would challenge traditional LLMs.

By combining these elements, agents can adapt to various tasks and domains, offering a more versatile and intelligent AI solution for real-world applications.

If we look into the future it appears that while base models are not yet capable of completing very complex tasks, agents will fill the gap, most likely in specialized concrete processes that have a clear testable outcome.
