Language models such as GPT, BERT, and their successors excel at generating fluent prose and correct grammar but lack metalinguistic awareness.
Metalinguistic awareness, a human cognitive ability, involves reflecting on language as a system independent of its communicative function.
AI models operate through statistical prediction and lack the ability for structural analysis, reflective abstraction, and intentional reasoning.
The absence of metalinguistic judgment in AI has practical consequences, making AI outputs opaque and non-instructive in contexts requiring deeper language understanding.
