Can I ask what is your purpose to keep up with it? The answer can better direct your actions.

E.g: If you don't want to miss out on groundbreaking tools, just casualy visiting HN will allow such projects to hit you in the face when they get enough momentum

if you want to dive in AI as a technology then start doing courses on ML and then neural networks and move on from there to other AI tech.

if you are just curious to obeserve what is happening in this innovative space, I would join some project's discord where tons of discussions are happening and people share tons of resources and projects with each other, eg auto-gpt discord is such a place
