I play the NYT connections pretty regularly. Today's (#25332) purple group was slightly more tenuous than real NYT games. Often good purple groups are both difficult to infer, but also the grouping makes more sense. Good connections puzzles will have fake-out groupings, forcing you to try and find as many groups as possible before making a guess. But still I was impressed by this one!

But on my second puzzle (#25049) I had two groups all come up in a row, I don't think the NYT one ever does this – which now makes me think you could shuffle their puzzle a bunch of times to find out the connections. And these connections were dead simple apart from purple which didn't make sense. And "Things You Container" is not correct English.

It's not bad for a vibe-code. But I'd be inclined to stick to the lovingly human-created NYT puzzles.
