You can find content like this on Twitter if you follow the right people. In fact I read this article before it was even posted here because @karpathy tweeted about it.

Mastodon is a good way to get at this content in unfiltered form. Take a look at the raw feed of the sigmoid.social instance or follow the #LLM hashtag.

If you want it more predigested and summarized I can recommend the AI Explained channel on youtube.
