The article cited by The Register cites this more detailed analysis in return: https://blog.katanaquant.com/p/your-llm-doesnt-write-correct-code
Performance of the AI-generated version was 20,000 times slower on one specific benchmark, but "only" about 2,000 times slower when averaging over multiple different benchmarks (which is, imo, a better measurement of the code's quality).
So I suppose The Register pulled from multiple sources (as you should) and just linked to the most top-level of all of them.
I think there's some trans specific aspects of clothesmaking, because our bodies do not always fit the expectations of cisgender clothes designers, tool makers, etc. leading to specific questions around finding suitable patterns if, say, you're a tall transfem (it me), or finding suitable mannequins if you want to shell out on one of those, or whatever.
So that's why I think having a community specifically for trans sewers is nice.
