DALLE-2 has a secret language. "Apoploe vesrreaitais" means birds. "Contarra ccetnxniams luryca tanniounons" means bugs or pests.

The poster asked DALLE-2 to produce seemingly nonsense words, and then prompt DALL-E with these words and find that these nonsense words contain meanings coherent to the initial prompt.

It's no longer seem like a mystery to me after I read explanations. But it's undoubtfully a super interesting phenomenom.
