There's an implication in the messaging of most of these blogs that LLMs and the approach the blog describes, is verging on AGI.

No, there isn't. People talk about AGI, including the CEOs of frontier model companies, but this isn't a post about that; it's very specifically a post about the workaday applications of LLMs as they exist today. (I don't think AGI will ever exist and don't care about it either way.)
