Constructing an AI Agent Tutorial – Half 1

Using the time period “AI Agent” has elevated by 10x within the final 1 12 months, as per information from Google Tendencies. This surge displays a broader shift: individuals and organizations more and more need AI Techniques that not solely reply questions, but in addition take actions on their behalf. From simplifying mundane duties to streamlining enterprise operations, the promise of Agentic AI is capturing international consideration.

So, what does this actually imply in apply? Let’s begin with a relatable situation of how AI Brokers can remodel on a regular basis duties within the close to future. Think about planning for a trip, which entails reserving resorts, flights, and rental vehicles. At present, this course of is fragmented and time-consuming. In an Agentic AI world, nevertheless, we might merely present a easy immediate that may generate tailor-made journey packages, full with itineraries, eating places, and bookings.

Right here is an instance immediate that might work in such a situation:

“I want to guide a household journey with 2 youngsters within the months of June/July for a weekend plus 2 days. Don’t embrace the 2nd week and third week of June. I’d simply want to hold two cabin baggage, and like tasting the perfect native meals. Plan for an itinerary not longer than 2-3 hours drive from town.”

On this article, we are going to transcend the buzzword that’s AI Brokers. You’ll first perceive the basics of AI Brokers after which discover the platforms that make them attainable. Lastly, we are going to construct a hands-on undertaking: a YouTube Summarizer Agent utilizing the Phidata framework. By the top, you’ll know what Agentic AI is and how one can begin constructing one with the SOTA instruments.

Be aware: That is the primary article in a two-part sequence on constructing AI Brokers from the bottom up. On this article, we are going to discover the worth of AI Brokers, introduce common Agentic AI platforms, and stroll by a hands-on tutorial for constructing a easy AI Agent. The subsequent a part of the sequence will dive deeper with a hands-on tutorial. There, we are going to construct Brokers that may automate duties and work together with exterior instruments and APIs.

Fundamentals of AI Brokers

In easy phrases, AI Brokers are techniques that may carry out duties autonomously by deciphering the info from the atmosphere. AI brokers could make selections based mostly on that information to realize the objectives. Consider them as orchestrators, connecting varied instruments, utilizing Massive Language Fashions (LLM) to motive, plan, and execute duties. For an in depth introduction to LLMs, you’ll be able to consult with this text.

Let’s break down this definition utilizing the above trip planning instance:

• Carry out duties autonomously: Ebook flight, lodge, and rental automotive reservations by the respective distributors.
• Deciphering the info: Account for components like climate, site visitors, and native occasions to counsel the perfect actions that match the tempo.
• Making selections: Take into account there are dozens of eating places accessible, Brokers can present suggestions based mostly on the indicated desire and previous opinions.
• Obtain objectives: Put collectively a journey plan that matches the necessities – dates, period, preferences, and household wants.

Agentic AI Platforms

An Agentic AI framework is a toolkit that allows the creation of AI techniques able to reasoning, planning, and taking actions autonomously or semi-autonomously by software use and reminiscence. In brief, these frameworks present the construction wanted to create brokers.

There are a number of common Agentic AI platforms, corresponding to LangChain, CrewAI, and Phidata. For this tutorial, we are going to use Phidata – a light-weight and developer-friendly platform. Phidata comes with built-in entry to a wide range of instruments and LLMs. This enables us to construct and deploy AI Brokers inside just some traces of code.

Construct a YouTube summarizer Agent

The YouTube Summarizer Agent is designed to extract key insights and details from any YouTube video. It saves time by offering concise summaries without having to look at your complete content material. For the aim of the tutorial, we are going to use Google Colab pocket book to jot down and execute the code and Phidata Agentic AI Platform to energy the Agent.

Mannequin: Inside Phidata, we are going to leverage the Groq mannequin internet hosting platform. It’s an inference service that runs LLMs on a devoted GPU infrastructure. Be aware that it’s totally different from Grok, which is an LLM from xAI. Since LLMs are resource-intensive, utilizing Groq helps to dump computation from the native {hardware} or Colab-provided {hardware}. This ensures sooner and extra environment friendly execution. Groq has entry to a number of fashions from totally different LLM suppliers. (see full checklist right here)

Instruments: To retrieve YouTube video information, we are going to use the built-in Instrument from the Phidata framework (known as YouTube Instruments). This software helps us entry video metadata and captions. The agent then passes these to the chosen LLM to generate correct and insightful summaries.

Right here is the code for a YouTube summarizer agent:

from phi.agent import Agent
from phi.mannequin.groq import Groq
from phi.mannequin.openai import OpenAIChat
from phi.instruments.youtube_tools import YouTubeTools


agent = Agent(
    # mannequin=Groq(id="llama3-8b-8192"),
    mannequin=Groq(id="llama-3.3-70b-versatile"),  ## Toggle with totally different LLM mannequin
    instruments=[YouTubeTools()],
    show_tool_calls=True,
    # debug_mode=True,
    description="You're a YouTube agent. Receive the captions of a YouTube video and reply questions.",
)


agent.print_response("Summarize this video https://www.youtube.com/watch?v=vStJoetOxJg", markdown=True, stream=True)

Following is the output generated by the YouTube Summarizer agent (above code). The YouTube hyperlink within the above code is a video of Andrew Ng on the Machine Studying specialization. As proven beneath, it precisely summarizes the video content material. Be aware that the response could differ for every run due to the probabilistic nature of LLMs.

Detailed Tutorial

Listed below are the step-by-step directions for creating the YouTube Summarizer agent.

1. Clone Pocket book

• Clone Colab pocket book right here (it requires a Google account)
• Set up dependencies (first cell with code)

2. Get API key for Groq

In an effort to run the Agent, provided that we use the Groq mannequin internet hosting platform, we want an account with Groq. Observe the steps beneath to enroll / log in to Groq and get an API key.

– Go to the Groq Developer Portal: Open your browser and go to: https://console.groq.com

– Signal Up or Log In

• If you have already got an account, click on Log In.
• In the event you’re new, click on Signal Up and observe the prompts to create an account (you might must confirm your electronic mail).

– Entry the API Part

• As soon as logged in, you’ll land on the Groq Console.
• Navigate to the API Keys part from the sidebar or dashboard.

– Generate a New API Key

• Click on the “Create API Key” button.
• Give your key a reputation (e.g., “workshop-key”).
• Click on Create or Generate.

– Copy and Retailer the Key Securely

• Your API key can be proven solely as soon as — copy it instantly and retailer it in a safe location.
• By no means expose your API key in client-side code or public repositories.

3. Add the API key within the Secret Supervisor

• Click on on Secrets and techniques (Key signal) on the left pane of Colab
• Present the title as GROQ_API_KEY and the Worth because the API Key copied in Step 5 above
• Toggle “ON” the pocket book entry.

Conclusion

On this article, we explored the rising demand for an AI Agent and walked by a real-world instance of how they will simplify on a regular basis duties. We broke down the basics of AI Brokers and a few common Agentic AI Frameworks. We additionally constructed a hands-on undertaking: a YouTube Summarizer Agent powered by Phidata.

That is just the start. Within the second article of this sequence, we are going to go deeper by constructing a research planner agent that doesn’t simply generate plans but in addition takes actions. It’ll create duties in Jira, ship calendar invitations, and exhibit how AI Brokers can seamlessly combine with exterior instruments and APIs to automate real-world workflows.
