The Illustrated Guide to AI Agents

New book announcement!

Thrilled that together with @maartengr.bsky.social , we're writing a new book titled “An Illustrated Guide to AI Agents” and published by @oreilly.bsky.social.

Excited to share that @jayalammar.bsky.social and I are writing the book “An Illustrated Guide to AI Agents” with @oreilly.bsky.social 🥳

Our new book will contain chapters on the fundamentals of agents (memory, tools, and planning), alongside more advanced concepts like RL and reasoning LLMs.

We've made so much extra (free!) content it could be its own book 😅

I counted more than 300 visuals across our illustrated and visual guides!

Happy to introduce my video on this alternative LLM architecture, Mamba and State Space Models!

I wanted to do it for a while now and finally found the time to work on animating my visual guide. Expect to gain an intuitive understanding of this alternative LLM architecture.

I discuss Model Context Protocol (MCP) in an upcoming article and figured I would share a small video illustrating a simplified flow!

Blazingly fast keyword generation with KeyBERT v0.9 and Model2Vec 🔥

I have been a big fan of the amazing embedding models by The Minish Lab, so I had to integrate them with KeyBERT.

A release for the GPU-poor 😉

Did you know we continue to develop new content for the "Hands-On Large Language Models" book?

There's now even a free course available with

I'm incredibly grateful that "Exploring Language Models" has reached over 10k subscribers🔥

A big thank you to all readers who have enjoyed my visual guides to Mixture of Experts (MoE), Quantization, State Space Models (SSMs) and Mamba 🤗

I started working on animating "A Visual Guide to Mamba" and it's been a blast.

Perhaps I should just add animations as a default to upcoming visual guides 😉

🍿 Introducing the animated "Visual Guide to Mixture of Experts (MoE)"!

This was a blast to make and contains more in-depth descriptions than the original already had! Expect even more intuition as we break down visuals and discover the nuances behind MoE.

Next up, "A Visual Guide to Quantization"!

Over 60 custom visuals explaining quantization of LLMs.

Explore (a)symmetric quantization, dynamic/static quantization, post-training techniques (e.g., GPTQ and GGUF), quantization-aware training (e.g., BitNet 1.58b), and more!

👋 Hi, I'm Maarten. I enjoy demystifying LLMs in the form of visual guides.

In the upcoming weeks, I'll be (re-)sharing some of my work if you are not already familiar with it.

Today, with more than 50 illustrations:
