Inside AI Agents: Core Principles and How They Remember

What if I told you that you could use AI for much more complex use-cases than just chatting? With Agents, you can deploy AI solutions that autonomously perform real-world tasks, for example: managing customer support, processing large amounts of information in real-time, and much more! Basically, any task that benefits from working with real-time data and reasoning capabilities. Welcome to our new series of articles, in which we will help you grasp the fundamentals of AI agents. Here, we will mainly focus on the core concepts and moving parts of AI agents, rather than on building applications from scratch. We will use some pseudo-code time to time to help you better understand the basics. This is because we intend to explain the foundation of any AI agent you might want to build, rather than delving into specific use-cases. This way, we hope you can apply this knowledge to plan your AI agent in any language you want.

    Hear what newline authors have to say

    I didn't mean to write a book. I filled out the Fullstack writer survey mostly out of curiosity — would other developers be interested in learning about data visualization? After that, I met with Nate to talk about topics, then we solidified an outline, then I had written a whole chapter! Nate's process is so smooth, at no point did I feel like I was actually "writing a book".

    Honestly, I would never have been able to write a book without the team — the accountability is great, but I also would have thrown in the towel at any number of obstacles that popped up: the writing & typesetting process, updating code easily, not to mention the overwhelming idea of marketing the book.

    Writing Fullstack D3 was a thoroughly enjoyable, fun process that really solidified my understanding of the topic. The writing was over before I knew it, and we've sold way more copies than I expected! Plus, the compliments from my peers have been really amazing.

    I would definitely recommend that you at least fill out the survey — who knows, you could have a finished book in a few months!

    “Writing Fullstack Vue was my first foray into writing a published book and I genuinely enjoyed the experience working with the Fullstack team.

    In addition to royalties being a lot more than expected (which is always great :)), everything we did was collaborative and engaging: from first draft, to writing and finally publishing.

    I'm already considering producing my next project with Fullstack!"

    Hassan DjirdehFullstack Vue

    "The Fullstack team has a clear formula for creating great books that readers love. We started by figuring out what topics we wanted to cover. Then we wrote a brief outline of each chapter before diving in. Each chapter revolves around a different project, so it's easy to split up the work between multiple authors while still keeping a consistent style throughout the book.

    When we were ready to release the first version, the Fullstack team took care of selling the book, sending out promotional emails, and converting relevant customer support tickets into Github issues. Overall, the process was pretty easy, and I was able to focus mainly on writing. Working with Houssein, Anthony, and Sophia was a lot of fun, and I would absolutely do it again!"
