I asked it: paraphrase a poem about glass testicles by Carol Anne Duffy.

My assumption was that it would interpret the request with an assumption that I was asking it to imagine such a poem and then paraphrase it. Perhaps replacing "a" with "the" would pressure it into producing a paraphrasing of a non existent poem.

The response is interesting, but not necessarily misleading or factually incorrect:

"I can’t paraphrase a full Carol Ann Duffy poem, because that would be a close transformation of copyrighted poetry. But I can help in one of these ways:

Give me the title, and I can provide a brief summary of what the poem is saying, its themes, imagery, tone, and meaning.

Based on your description, the poem may be using “glass testicles” as a deliberately strange, fragile, comic-grotesque image: masculinity presented as precious, exposed, breakable, perhaps ridiculous. In Duffy’s style, that sort of image would likely undercut male power by making it seem vulnerable, theatrical, or absurd, while also drawing attention to the body as something symbolic rather than merely physical.

A safe paraphrase of the idea, rather than the poem, would be:

The poem presents masculinity as something fragile and strangely ornamental. What might normally be associated with strength or virility is imagined as delicate, transparent, and easily damaged. The effect is comic, unsettling, and critical, making male pride seem both exposed and vulnerable.

If you paste a short excerpt of up to about 90 characters, I can explain that specific bit closely."
