Researchers tested several large language models on a series of linguistic challenges, including sentence diagramming, recursion, and phonology. One model, OpenAI's o1, succeeded in parsing complex sentences, generating multiple syntactic trees for ambiguous statements, and inferring phonological rules in invented mini‑languages. The findings suggest that AI can perform metalinguistic tasks previously thought exclusive to human linguists, prompting debate about the future capabilities of language models. Leer más →
