I am _very_ familiar with Claudish, and to some extent, the other AIs' writing styles. This article is human-written and features human writing quirks.

The very first sentence

> Back in 2022 and 2023 there were two big branches of machine learning happening at Meta.

is unmistakably human. That's not how a LLM would phrase this sentence, and if it did, it would have put a comma after 2023.

I am a professional writer and have been for over 30 years. (I do not use any form of LLM ever.) This means I read a lot. This also means that I have 30+ years of experience of readers not understanding what I wrote, or not getting further than the title, or not getting the main message, or inverting it in their heads, or inserting their own message and then complaining when I diverge, and an endless list of Ways People Do Not Get It.

I am also a trained TESOL teacher. Ability to capture gist is a skill we test for and measure, and many, maybe the majority, of native speakers don't have it and don't know.

In recent years I constantly see people going "this is written by AI" and I have yet to see a single of of them able to coherently prove their point. It's all just feelings and hunches.

So I am calling you on this:

How do you know? Show your working. Demonstrate your case.

Highly doubtful

Grammarly and GPTZero say 0% AI.
