The recently released models have improved their writing styles. I don't know about this article, but if that's any indication of their writing habits, the author's github pages repo is full of posts generated by Claude.

IMO, the article is well-written.

The author's picture clearly has an LLM-generated background, (and is a little tacky, IMO.) That being said, I wouldn't dismiss an article merely because someone used an LLM while setting up their blog.

The whole structure had a faint smell to it. It's hard to put into word, there was no obvious "it's not the quiet part. It's the load bearing bedrock", but the way the thing flowed made me strongly suspect LLM involvement.
