I have tested them on novel Winograd schemas, they didn't pass; that's why I said what I said. Your second schema was incorrectly constructed, in both the first and second sentence the pluralisation of the pronoun in question gives away the answer. "It" won't apply to "flowers" because they're plural, and "they were" won't apply to "the greenhouse" because it's singular. As a result, those sentences aren't Winograd schemas because they're not testing common sense pronoun attribution specifically, they're testing the ability to maintain plural status consistency, which is doable by much less intelligent systems. It's also standard to ask "What does the pronoun '[pronoun]' refer to in that sentence?" rather than "What was too small?" or similar, as using descriptive words is also giving away information that you're meant to be testing the model on. But plenty of people make that mistake, so it's not that important.

Summing up, out of your four (not an acceptable sample size to form evidence) attempts to subject a SOTA LLM to Winograd schemas, two of them were actually Winograd schemas and only one of those got answered correctly. That isn't evidence that LLMs can pass novel Winograd schemas. If you actually come across such evidence, you should post it publicly on at least a blog page if you can't access the infrastructure to publish the results in a paper, even though the finding would certainly be novel enough to deserve a paper. As I said: there is no evidence that LLMs can pass novel Winograd schemas as of yet. We could get said evidence tomorrow, but it doesn't exist right now.

I would put a condescending moral of the story here, but I don't feel any particular need to belittle you, and instead hope you just learn from the information as presented.
