Everyone is talking about AI agents. Almost nobody explains what they actually are or how to build one. That changes right now.

Here's the honest one-sentence version: an AI agent is a language model that can use tools, running in a loop until it finishes a job. That's it. Everything else is just details — and in this video I break all of those details down clearly, then show you how to build the same agent in four completely different ways.

Bro you are hidden gem.. you actually talk about practical stuff and avoid noise and jargon.

This was one of the clearest explanations of AI agents I've seen in a while. I liked that you didn't just define what an agent is—you actually showed how the pieces fit together when building one. We've been exploring similar AI engineering ideas at Leanware, so it's always interesting to see different approaches. Looking forward to more content like this.!

You're an incredible teacher who simplifies complex concepts by removing hype and explaining things fundamentally. When someone seeks honest, hype-free truth, I always recommend your channel. I truly appreciate your work. ❤

Hi, Tim. I have been semi-retired for about four years and I'm just re-entering the business, obviously needing to learn AI, agents, etc. This is the best video I have seen yet on AI-related topics and especially agents and your ability to speak in an understandable way is a powerful skill. You're at the top. I will continue to visit your channel. I learned more from your one video on agents than the other 15 I have watched in the last two weeks. Thanks again.

This way of teaching is actually what hits the brain. Most of the other teachers just explain the theory, which has got no information whatsoever about its practical implementation.

I really liked the distinction between chatbots and agents. Feels like a lot of the confusion online comes from calling everything an "AI agent" when it's really just an LLM with a prompt.

Finally someone who explains it properly

Sounds like a main program in the industrial robot programming concept. It will activate different subprograms to perform a specific function to perform a specific task then return back to the main program so it can repeat the same process over and over again. That's how a robot runs all day in automatic mode without any human intervention.

A 1,000+ videos later... I found the best one. Great work!

bro is like you read our minds what we want to know and when.

The way you present is worth sharing This deserves recognition.

Excellent video! Good job. Dumbed it down enough that I could understand a technical subject!

@FrankRiccardi-Author 2 weeks ago

Hands down the best video I’ve seen yet explaining what an AI agent is from a technical perspective. I am now a subscriber of your channel!

@muhammedhassan5665 1 month ago (edited)

Thanks! Straight to the point. concise without being shallow. even showing how they look in practice!

Actually this is a very good explanation video

great example of how fast everything is moving into the transduction because two months later anybody can sign up for an assistant that will do it all for you and abstract and you away from needing to understand much of any of it. this changed in two months. this is a different acceleration than something like Moore's law it's more like 75x faster and compounding do the math, it's a pretty certain outcome unless you turn it all off before you can't

Your videos are the absolute best! Set this up right away. Thanks.

Breaking them down into tools + a loop, then showing four different ways to build one, makes the concept much easier to understand. Great structure for anyone trying to move from AI theory to actually building agents.
