Differential syntactic and semantic encoding in LLMs
Researchers studying DeepSeek-V3 discovered that Large Language Models encode syntactic and semantic information in mathematically separable, linear patterns within their hidden layers. By averaging representations of sentences with shared structure or meaning, they created 'centroids' that capture significant linguistic information, revealing that syntax and semantics are processed through distinct, partially decoupled mechanisms across different layers.
