First-Token Broadcasters: Mechanistic Origins of Language Identity and Distributed Robustness in Transformers

Researchers identify specific attention heads in multilingual language models responsible for language switching errors, revealing that instruction tuning reorganizes these circuits to concentrate language identity signals in early layers. The study demonstrates that language selection operates through a distributed but hierarchical mechanism, with compensation patterns following predictable feedforward cascades rather than global diffusion.

Space-Efficient Language Generation in the Limit

Researchers present a theoretical framework for space-efficient language generation that characterizes the tradeoff between memory constraints and learning accuracy. Using polynomial space, a streaming algorithm can identify most strings in a target language while missing at most O(k^(2s-2)) strings, with a matching lower bound proving this gap is near-optimal.
