In this guide, we’ll walk you through the process of creating a fully functional multi-agent AI system using Watsonx.ai and CrewAI, integrating multiple LLMs, assigning distinct tasks, and automating web-based research and content generation. Whether you’re an AI enthusiast or a developer looking to build intelligent automation workflows, this article provides a comprehensive, hands-on blueprint to get started.

Understanding the Building Blocks of Multi-Agent Systems

At the heart of a multi-agent AI system is the concept of agent specialization. Rather than relying on a single, monolithic model, the system consists of several agents—each powered by a specific LLM—assigned with unique roles, tasks, and goals. These agents interact with one another, communicate outputs, and even delegate responsibilities when needed.

The architecture generally includes:

• Core LLMs to handle content generation and reasoning.
• Function-calling LLMs to interface with APIs or tools.
• Agents that encapsulate persona, goals, and domain expertise.
• Tasks assigned to specific agents.
• Crew or Orchestrator that manages execution and communication across agents.

Step 1: Setting Up the Environment

To begin building, we first import key dependencies:

• CrewAI: The orchestrator framework that enables multi-agent coordination.
• Watsonx.ai LLM SDK: To connect IBM’s hosted language models.
• Langchain tools: For enabling external data access, like web search via Serper.dev.
• OS module: For securely managing API credentials.

You’ll need API keys for both Watsonx.ai and Serper.dev to make your system internet-capable and cloud-integrated.

Step 2: Configuring Your Large Language Models (LLMs)

The system uses two different LLMs:

1. LLaMA 3 70B Instruct (from Meta, via Watsonx): This is the primary generation model for reasoning and research.
2. Merlinite-7B (an IBM model): Handles function calling and is optimized for tasks like summarization and formatting.

These models are configured by setting:

• Model ID: A unique identifier for the selected LLM (e.g., meta-llama/llama-3-70b-instruct).
• API URL: Endpoint for Watsonx deployment.
• Project ID: For tracking and managing workloads.
• Decoding parameters: Such as greedy decoding and max_new_tokens, which control output length and generation style.

This dual-model approach allows for separation of concerns—one model thinks, the other executes.

Step 3: Creating the First Agent — The Researcher

The first AI agent you create is a Senior AI Researcher. This agent’s task is to explore the web and identify promising AI research, particularly in the field of quantum computing.

The agent is defined by:

• Role: Senior AI researcher
• Goal: Identify breakthrough trends in quantum AI
• Backstory: A veteran in quantum computing with a strong physics background
• Tools: Connected to Serper.dev to perform live web searches
• LLMs: Uses both LLaMA 3 and Merlinite for generation and function calling

Once the agent is initialized, it is assigned a task:

• Description: Search the internet for five examples of promising AI research.
• Expected Output: A bullet-point summary covering background, utility, and relevance.
• Output File: Saved as a .txt file for later use.

The CrewAI framework is used to assign this task to the agent and run the job.

Step 4: Running the First Agent

Upon execution, the researcher agent connects to the web via the integrated Serper.dev tool, fetches relevant articles and papers, processes them using LLaMA 3, and then compiles a structured summary.

This step demonstrates the core capability of an AI agent:

• Independently navigating a knowledge base (the internet)
• Extracting meaningful data
• Organizing it into a coherent output file

At this point, you have a fully functional single-agent AI system. But the goal is to build multi-agent intelligence, so we move to the next phase.

Step 5: Adding the Second Agent — The Speechwriter

The second agent in the system is a Senior Speechwriter, whose job is to turn the research from the first agent into an engaging keynote address.

This agent differs from the first in key ways:

• Role: Expert communicator with experience writing for executives
• Goal: Transform technical content into accessible, compelling speeches
• Backstory: A seasoned science communicator with a flair for narrative
• Tools: This agent doesn’t require web access—it relies solely on internal data

A new task is assigned to the writer agent:

• Description: Craft a keynote speech on quantum computing using the prior research.
• Expected Output: A complete speech with an introduction, body, and conclusion.
• Output File: Saved separately as a text file for review or public use.

Step 6: Orchestrating a Multi-Agent Workflow

The real magic happens when both agents are assigned to the Crew, and tasks are executed in sequence.

• First, the Researcher agent runs and generates task1_output.txt.
• Next, the Speechwriter agent picks up the content of task1_output.txt and transforms it into a keynote saved as task2_output.txt.

This chain illustrates a basic pipeline of intelligent delegation—an LLM-driven research-to-content-production pipeline.

It’s worth noting that the system currently executes tasks in a fixed order, but future versions could allow dynamic delegation, where agents decide among themselves who’s best suited for each task.

Debugging and Execution Insights

During execution, small bugs—such as assigning the wrong agent to a task—can occur. In the demo, the same agent was mistakenly assigned to both tasks initially. This was quickly corrected by specifying the correct agent object in the task definition.

This highlights an important lesson: as multi-agent systems grow in complexity, agent-task mapping and error handling become essential to maintain reliability.

Final Outputs and Results

Once the system runs successfully:

• task1_output.txt contains a well-structured list of current AI + Quantum research, including areas like Quantum Optimization, Quantum Neural Networks, and Reinforcement Learning.
• task2_output.txt delivers a speech starting with a warm welcome and leading into the transformative power of Quantum Computing in AI, illustrating its potential to redefine innovation.

The ability to go from web-based research to polished, publish-ready content through autonomous AI agents is not only remarkable—it’s incredibly useful.

Expanding the System Further

What was demonstrated is only a minimum viable multi-agent system. This system could be further enhanced by:

• Adding more agents: editors, data analysts, graphic designers
• Enabling delegation logic: where agents choose tasks dynamically
• Introducing memory: to maintain continuity across long projects
• Scaling horizontally: run multiple tasks in parallel

Why Watsonx.ai and CrewAI?

Watsonx.ai provides:

• Access to powerful LLMs like LLaMA 3 and Merlinite
• Enterprise-ready deployment across regions
• Security and project management for data science workflows

CrewAI offers:

• A clean orchestration framework for multi-agent coordination
• Modular agent and task definition
• Integration with external tools like Serper.dev, GitHub, CSV parsers, and more

Together, they create a powerful stack for building complex, distributed AI systems.

Conclusion: Multi-Agent AI Is the Future

Multi-agent systems represent a seismic shift in how we approach problem-solving with AI. By distributing intelligence across roles—just like in human teams—we unlock a new level of automation, flexibility, and performance.

What began as a 15-minute demo ends with a framework that can be applied to enterprise automation, content generation, scientific research, and beyond.

With platforms like Watsonx.ai and CrewAI, the barriers to building advanced multi-agent systems have never been lower. The question isn’t whether you can build one—it’s what kind of team of agents you’ll assemble next.

Whether you’re aiming to automate internal workflows or pioneer the next AI-powered product, the tools are here—and they’re free, flexible, and open for innovation.

So pick your framework, start building, and let your AI agents take the lead.

The post Top open-source frameworks for building AI agents and agentic AI applications appeared first on RoboticsBiz.

Unlike a one-time chatbot response or a static automation script, AI agents represent a growing class of intelligent systems that can break down complex tasks, interact with multiple tools, collaborate with other agents, and iteratively improve their own output. They aren’t just executing commands — they’re reasoning, planning, and adapting in ways that mimic human workflows.

In this article, we’ll explore what AI agents really are, how they differ from traditional AI use, and why they’re critical to the next evolution of software. We’ll also delve into agentic workflows, multi-agent systems, and the practical frameworks that developers and businesses can use today — even with no code.

What Are AI Agents? Separating Hype from Reality

Defining an AI agent may sound simple, but in reality, it’s a fast-evolving field where boundaries are still being explored. At its core, an AI agent is a system that doesn’t just respond to a single prompt — it acts, reflects, and improves over time by interacting with its environment, tools, and other agents.

Beyond One-Shot Prompts

A traditional AI interaction might look like this: “Write an essay about climate change.” The AI responds with a coherent answer, but it’s static — there’s no reflection, iteration, or adjustment based on feedback.

An AI agent, by contrast, approaches the task as a process. It might:

• Start by outlining key points.
• Check for gaps or conduct research using a web tool.
• Draft a version of the essay.
• Critically review and revise it.
• Finalize the output based on internal logic or collaborative feedback.

This circular process — think, do, reflect, refine — is what distinguishes an agentic workflow from traditional one-shot interactions.

The Agentic Ladder: From Prompts to Autonomy

There are levels to this new AI behavior:

• Basic Prompting — A single request yields a single response. No iteration.
• Agentic Workflow — The task is broken into sub-steps, revisited iteratively.
• Autonomous AI Agents — The system independently determines goals, tools, and workflows, improving over time without human guidance.

While we’re not yet at full autonomy across all domains, many AI systems today already function at level two, thanks to breakthroughs in agent design and tool integration.

Four Core Patterns of Agentic Design

To understand how AI agents function, it’s helpful to look at four widely accepted agentic patterns:

1. Reflection

Reflection is when an AI reviews and critiques its own output. For example, after writing code, it can be instructed — or prompted by another AI — to check for logic errors, inefficiencies, or style issues. This creates a feedback loop, enabling improvement.

2. Tool Use

Agents equipped with tools can perform tasks that go beyond language. For instance:

• Search the internet for real-time information.
• Use a calculator or code interpreter.
• Access email and calendars to schedule events.
• Perform image generation or recognition.

By integrating tool use, AI agents become far more capable than static chat interfaces.

3. Planning and Reasoning

Planning agents can break a high-level task into smaller sub-goals and determine which tools to use at each stage. For example, generating an image based on pose recognition from a reference file involves multiple steps — each potentially executed by different models or tools.

4. Multi-Agent Collaboration

Inspired by human teams, multi-agent systems distribute tasks across specialized agents. Rather than one model doing everything, different agents handle writing, editing, researching, coding, or decision-making. Collaboration and role specialization lead to more accurate, efficient, and modular workflows.

Multi-Agent Architectures: Building Smarter AI Teams

A single agent can be powerful, but a group of agents working together — like a well-organized team — unlocks new levels of performance. Based on insights from Crew AI and DeepLearning.AI, we now have several design patterns that underpin these collaborative systems:

Sequential Workflow

Agents pass tasks down a pipeline, like an assembly line. One extracts text, the next summarizes it, another pulls action items, and the final one stores the data. This is common in document processing and structured automation.

Hierarchical Agent Systems

Here, a manager agent assigns tasks to subordinate agents based on their specialties. For example, in business analytics, one sub-agent may track market trends, another customer sentiment, and another product metrics — all reporting to a decision-making agent.

Hybrid Models

In complex domains like autonomous vehicles or robotics, agents operate both hierarchically and in parallel. A high-level planner oversees route optimization, while sub-agents continuously monitor sensors, traffic, and road conditions, feeding updates in real time.

Parallel Systems

Agents independently process separate workstreams simultaneously. This is especially useful for data analysis, where large datasets are chunked and processed in parallel before merging results.

Asynchronous Systems

Agents execute tasks at different times and react to specific triggers. This is ideal for real-time systems like cybersecurity threat detection, where various agents monitor different aspects of a network and respond independently to anomalies.

No-Code Agent Development: Building an AI Assistant with N8N

The power of agents isn’t limited to expert coders. Platforms like n8n enable anyone to build multi-agent systems using drag-and-drop workflows. For example:

• An AI assistant on Telegram named InkyBot listens to your voice or text.
• It converts voice to text using OpenAI’s transcription.
• It interprets your message, checks your Google Calendar, and helps prioritize tasks.
• It then schedules new events, updates you, and continues the conversation — all without code.

This workflow mirrors the T-A-M-T model (Task, Answer, Model, Tools):

• Task: Prioritize tasks for the day.
• Answer: A to-do list and scheduled calendar events.
• Model: GPT-4 (or any compatible LLM).
• Tools: Calendar APIs, transcription services, messaging platforms.

As simple as this example is, adding more agents or tools can result in highly advanced personal assistants, customer service bots, or research analysts — all built without writing a single line of code.

Opportunities: Why AI Agents Are the Next SaaS Boom

One of the most compelling takeaways from AI agent development is this: for every traditional SaaS product, there’s now the opportunity to build its AI-agent-powered counterpart.

Instead of a project management platform, you can build a task delegation agent that manages human and AI workflows. Instead of a customer service dashboard, you can create an agent that triages, replies to, and escalates tickets. Think of verticalized AI agents for:

• Travel planning
• Content marketing
• Investment analysis
• Health tracking
• Legal document review

If you want to build something useful with AI, simply identify a SaaS product and envision how it could be transformed into an autonomous, intelligent agent-based workflow.

Challenges and Considerations

While AI agents are powerful, they also introduce new complexities:

• Error propagation: Mistakes made early in a workflow can cascade.
• Debugging: Multi-agent systems are harder to troubleshoot than single-model tools.
• Interpretability: With autonomous decision-making, it can be difficult to understand why an agent made a choice.
• Security: Agents accessing tools (like email or calendars) must be tightly governed to avoid misuse.

Still, with robust design, transparency, and human-in-the-loop supervision, these concerns can be addressed effectively.

Conclusion: Welcome to the Age of AI Agents

We’re entering a new era in artificial intelligence — one where machines don’t just respond to requests, but independently break down tasks, collaborate, and adapt. AI agents offer a compelling bridge between static automation and general AI. They empower us to build systems that can reason, plan, reflect, and even work in teams.

Whether you’re a solo entrepreneur, a researcher, a developer, or just an AI enthusiast, this is the moment to explore what agents can do. With the right tools and mindset, you can build intelligent systems that automate the unthinkable and unlock a new dimension of productivity.

And best of all — you don’t need to code to get started.

The post AI agents explained: Creating autonomous workflows without writing code appeared first on RoboticsBiz.

Some of the world’s largest tech companies—Apple and Amazon included—still struggle to implement reliable AI systems. Apple’s much-anticipated “Apple Intelligence” recently faced setbacks due to hallucinated outputs, while Amazon Alexa continues to falter in its AI transformation efforts.

So, what gives? Why is it so hard to build functional AI agents, and how can developers avoid the traps of overhyped tools and frameworks?

This article demystifies AI agent development. Rather than relying on buzzwords and flashy prototypes, it presents practical, tested approaches to building robust AI systems that deliver real value. Whether you’re a developer just stepping into the world of AI or an engineer aiming to take your applications to production, these insights will help you navigate the complexities—and the possibilities—of AI systems that actually work.

What Is an AI Agent, Really?

Before diving into architecture or tooling, let’s clarify the most fundamental (and often misunderstood) question: what even is an AI agent?

If you search for “how to build AI agents” online, most tutorials will walk you through a software flow with one or more calls to a large language model (LLM), like OpenAI’s GPT. But is a workflow that simply includes an LLM call truly an AI agent?

Not quite.

According to Anthropic’s widely respected distinction, there’s a critical difference between workflows and agents:

• Workflows are systems where LLMs and tools are orchestrated through predefined code paths.
• Agents, on the other hand, are systems where LLMs dynamically decide their own process and tool usage, maintaining control over how to complete a task.

Understanding this difference is vital for developers. Workflows are deterministic, testable, and controlled—great for production. Agents are flexible, autonomous, and powerful—but far more prone to errors and unpredictability.

Start Simple: Why You Often Don’t Need Agents

Here’s a hard truth: for most applications, you don’t need to build true agents. In fact, adding agentic complexity can introduce more problems than it solves.

As Anthropic’s blog suggests, and as years of industry practice confirm, the best approach is to find the simplest solution possible. Many tasks—especially in customer service, internal tools, and automation—can be handled using optimized LLM workflows, not agents.

A well-structured LLM call with retrieval, tools, and memory can often provide excellent results. This approach avoids the fragility of agents and makes debugging, optimization, and testing much easier.

Let’s explore how to actually design these systems.

Foundations of Reliable AI Systems

Building an effective AI system—whether workflow or agent—starts with mastering a few core components. Think of these as your building blocks:

Augmented LLMs

Rather than making a basic API call to ChatGPT, enhance your LLM’s capabilities with three key augmentations:

• Retrieval: Use a vector database (e.g., Pinecone, Weaviate) to fetch relevant documents or historical data at runtime. This gives your AI “long-term memory.”
• Tools: Allow the model to call external APIs (e.g., weather updates, shipment tracking) dynamically.
• Memory: Maintain the conversation history or session context, especially useful in chatbots or multi-step tasks.

When these elements are balanced, your app moves beyond being a mere wrapper around an LLM and becomes a contextually rich, responsive system.

Workflow Patterns That Work

Even if you’re not building a true agent, you can craft powerful AI-driven experiences using thoughtful patterns. Here are five proven ones:

1. Prompt Chaining

Instead of giving the LLM a huge task (e.g., “Write a blog post”), break it into manageable steps:

• Research the topic
• Choose a title
• Create an outline
• Write the introduction
• Expand into sections

Each step is handled by a separate LLM call, with results passed to the next. This modular approach enhances control and allows for better tuning and evaluation.

2. Routing

When your application has to handle multiple user intents, use LLMs to classify the input and route it accordingly.

Example: In a customer service app, the first LLM call determines if the issue is about a delayed order, refund request, or account access. Then, each case follows its own specialized workflow.

This structure offers clarity and scalability—start with one route, then expand.

3. Parallelization

For tasks that don’t depend on each other, run LLM calls simultaneously. This drastically improves speed.

Example: Evaluate an AI-generated answer across multiple safety checks—one for accuracy, one for toxicity, and one for prompt injection—in parallel.

4. Orchestrator–Worker Pattern

This hybrid pattern gets closer to agentic behavior without losing structure.

An orchestrator (usually an LLM) reads the input and determines what tasks need to happen. It then delegates to workers (specialized functions or API calls). Think of this like a conductor assigning parts to musicians.

It’s sequential, predictable, and still allows for dynamic decision-making.

5. Evaluator–Optimizer Loop

One LLM generates content, another evaluates it, and a third refines it based on feedback.

Example:

• LLM A writes an article
• LLM B critiques the article
• LLM C rewrites it using the critique

This loop is highly effective for refining outputs and building more reliable systems over time.

The True Agent Pattern: Power and Pitfalls

Now, what does a true agent look like?

Here’s the process:

1. The user gives a task.
2. The LLM chooses an action or tool.
3. The action is executed in an environment.
4. The result is observed and evaluated.
5. Feedback is fed back to the LLM.
6. Steps 2–5 repeat until the task is completed or fails.

This loop-based, feedback-driven design is what makes agents flexible. But it also makes them unpredictable. They can get stuck in loops, take inefficient paths, or hallucinate wildly. That’s why most agent systems today are not production-ready.

A high-profile example? Devin, the AI software engineer agent, wowed the internet with its ability to write and test code autonomously. But real-world use cases showed disappointing results—only a small fraction of tasks were completed successfully.

Final Tips for Developers Building AI Systems

1. Avoid Over-Engineering Too Soon

Agent frameworks (like LangChain, AutoGPT, etc.) can get you started quickly—but they often hide complexity. Learn the basics first: build your own routing, chaining, and tool-calling logic. This will make you a better engineer in the long run.

2. Start Narrow, Then Scale

Focus on a single, tightly scoped problem. For instance, instead of trying to automate an entire helpdesk, start with just “Where’s my order?” questions. Once that works flawlessly, expand.

3. Beware the Demo Trap

It’s easy to make something look great in a demo. But once your app is exposed to thousands of users, the edge cases, hallucinations, and errors will multiply. Expect chaos—and prepare for it.

4. Implement Guardrails

Before displaying results to users, run them through safety checks. It can be as simple as an LLM judging whether the output is toxic, false, or violates guidelines. Even giants like Amazon have dropped the ball here—don’t make the same mistake.

5. Build a Feedback Loop and Evaluation System Early

If you change a prompt or parameter, how do you know it improved things? Establish metrics and evaluation processes from day one. This makes iteration data-driven, not just gut-driven.

Conclusion: Simplicity is the Secret Weapon

The future of AI is undeniably exciting—but hype won’t build stable, scalable systems. If you’re a developer aiming to deliver value through AI, forget the buzzwords and start with strong engineering principles.

Master the core workflow patterns. Understand when you truly need an agentic architecture—and when a well-tuned workflow will do just fine. Prioritize reliability, observability, and continuous improvement. And above all, build with the real world in mind, not just the demo.

Because in the long run, the best AI agents won’t be the flashiest—they’ll be the ones that actually work.

  • URL Fetcher: To extract data from a website.
  • Calculator: To perform mathematical calculations.
  • Chat Input: To take user input and pass it to other agents.
  • Search Tools: To perform web searches using tools like DuckDuckGo.

These tools are designed to be simple and easy to use. Each tool has specific settings that you can configure to suit your needs.

• Drag and Drop to Build Flows: After selecting your tools, drag and drop them into your flow editor. LangFlow uses a visual workflow editor, so creating agents is as simple as connecting the right tools in the order you want. For example, you might add a search tool, connect it to a data fetching tool, and then display the results in a formatted output.

4. Configure Tool Settings

Once the tools are placed in the flow, you’ll need to configure them:

• Enter API Keys and Credentials: Some tools, like those for fetching URLs or querying APIs, may require you to enter specific credentials, such as API keys. For example, if you’re using OpenAI’s GPT models, you must provide your OpenAI API key. Similarly, if you’re using search tools, you may need to link your DuckDuckGo or Wikipedia API keys.
• Customize Tool Behavior: Each tool comes with specific options you can configure. For instance, if you’re using a URL fetcher, you’ll need to define the URL format and what type of content you want to extract (e.g., raw HTML, JSON, or text). If you’re using a calculator tool, you can define what type of operations the agent should handle.

5. Connect Tools and Create Logic

One of the best features of LangFlow is its drag-and-drop interface, which allows you to connect tools visually. This is how you build the logic of your AI agent:

• Connect Inputs to Outputs: For example, you can connect the chat input tool to the search tool so that whatever the user types is used as a query for the search tool. Similarly, you can connect the search tool’s output to the display tool, which will show the results in a readable format.
• Set Conditions and Logic: LangFlow allows you to define conditional logic, which determines how the tools behave based on their input. For example, if no relevant results are returned from a search query, you can define a fallback behavior, such as querying a different tool or displaying a default message.

6. Test Your Agent in the Playground

Once you’ve configured your agent and its workflow, you can test it before deployment:

• Launch the Playground: LangFlow provides an integrated playground where you can interact with your AI agent in real-time. Here, you can simulate queries and see how your agent behaves with live inputs.
• Enter Test Queries: In the playground, type in sample queries (e.g., “What is the weather like today?” or “Provide me with the latest AI news”) and observe how your agent fetches data, processes it and presents the results. You can also debug and adjust settings that don’t work as expected.

7. Deploy and Integrate Your Agent

After testing, you can deploy your AI agent and integrate it into your existing applications:

• Export API: LangFlow makes it easy to convert your flow into an API, which can then be integrated into other platforms. Whether you’re building a web app, a chatbot, or a mobile application, you can use the API to call your agent’s functionality.
• API Keys and Endpoints: LangFlow will provide the necessary API keys and endpoints. Integrate these into your application to allow your AI agent to perform tasks.

8. Iterate and Scale

As you continue working with LangFlow, you may want to enhance your agents or add new tools to improve their functionality:

• Add More Tools: LangFlow supports adding an unlimited number of tools. If you want to include more sophisticated AI models, advanced search capabilities, or integrations with third-party services, you can easily add them to your agent’s flow.
• Optimize for Scalability: If your application grows or requires more complex workflows, LangFlow’s low-code design allows you to scale it up efficiently. With LangFlow’s flexible structure, you can continuously iterate and enhance your AI agents to meet evolving needs.

While generative AI has dominated the conversation in recent years, there’s a rising shift towards a more autonomous, goal-driven approach known as Agentic AI. This shift could redefine the way AI systems are utilized across various sectors. Let’s delve into Agentic AI, how it differs from traditional generative AI, and why it’s gaining so much attention.

What is Agentic AI?

Agentic AI, often called Autonomous AI, represents a step beyond generative capabilities. While generative AI creates content, Agentic AI is designed to perform autonomous tasks to achieve a specific goal or business outcome. It goes beyond simply generating text or images by integrating tools and external data sources to accomplish complex workflows independently, without human intervention.

How Agentic AI Works:

• Autonomous Action: Agentic AI can autonomously integrate and interact with various external systems (like APIs, databases, news sources, etc.) to achieve a set goal. This could be anything from analyzing stock market data to automating customer service responses or solving logistical problems.
• Tool Integration: Agentic AI applications are typically designed to connect to external tools, like web scraping tools, APIs, or even databases, to gather and process the most relevant and up-to-date information needed to accomplish their tasks. For example, an agentic AI might access financial data to make stock-buying recommendations or gather customer feedback to refine a marketing campaign.
• Complex Workflow Execution: One of the most powerful features of Agentic AI is its ability to execute complex workflows that involve multiple stages of data collection, analysis, and decision-making. These workflows are often dynamic, meaning the AI agents may modify their actions or decisions as the process unfolds.
• Self-Improvement: Unlike generative AI, which focuses on producing content, Agentic AI is capable of self-learning and fine-tuning its behavior over time. As it gathers more information and completes tasks, it can adapt and improve its performance, leading to higher efficiency and more accurate results.

What Makes Agentic AI Autonomous?

Agentic AI takes generative AI a step further by incorporating autonomy. Here’s the key difference:

Generative AI creates content, like articles, poems, or summaries, based on predefined prompts.

On the other hand, Agentic AI performs actions autonomously to complete specific tasks, often involving multiple steps and interacting with external systems or tools to achieve a business or operational outcome.

For example, in a financial advisor AI system, an agentic AI could autonomously gather data from various financial tools, analyze market trends, and provide recommendations on stock investments—all without human intervention. This is a far more dynamic process than merely generating a financial report from a prompt.

At its core, agentic AI is designed to work towards a specific goal. To achieve this, the system interacts with several external tools, collects and analyzes data from various sources, and follows a structured workflow. The beauty of this approach lies in its flexibility: the system can adapt its process depending on the information it retrieves, optimize its performance, and even fine-tune itself to enhance its task completion.

For example, imagine an agentic AI tasked with recommending stocks to buy. It would autonomously:

• Gather the latest stock data from sources like YT Finance.
• Search for relevant news articles or sentiment analysis regarding those stocks.
• Analyze historical stock performance.
• Finally, provide a recommendation on which stock to purchase.

Each step is executed independently by different AI agents, all working in parallel to achieve the overall goal.

The Frameworks Powering Agentic AI

Several new frameworks are emerging to facilitate the development of agentic AI applications. These frameworks allow developers to create complex workflows, integrate various external tools, and deploy autonomous AI agents efficiently. Here are some of the most notable frameworks:
