Valuable Resources for Understanding AI Agents: First Principles

AI Agents can only be designed, built and applied well if the underlying components are understood to a sufficient level.
These are the resources that I found the most valuable so far for diving into those first principles, without getting “vendor-locked”. I believe we learn the most when we share our knowledge, so I’m happy to share these with you.

Courses
And of course, the courses and sessions offered by my colleagues at HOWEST University of Applied Sciences.
As you can see, I’m learning a ton and having fun! Which resources do you find most valuable?
