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.

Learning Multi-Indicator Weights for Data Selection: A Joint Task-Model Adaptation Framework with Efficient Proxies

Researchers propose a framework for optimizing data selection in large language model instruction tuning by learning task-specific and model-specific weights for multiple quality indicators. Using efficient in-context learning signals on small validation sets, the method achieves comparable performance to full-dataset training with only 30% of samples, revealing important trade-offs between semantic diversity and logical complexity.

Post-training makes large language models less human-like

Researchers introduced Psych-201, a dataset measuring how well large language models align with human behavior, and discovered that post-training—the process that makes base models into functional assistants—systematically reduces their human-likeness across all model families and sizes. This misalignment worsens with newer generations despite improvements in base model capabilities, suggesting that the optimization techniques making LLMs more useful for deployment make them worse at mimicking actual human behavior.

One Token Away from Collapse: The Fragility of Instruction-Tuned Helpfulness

Researchers demonstrate that instruction-tuned large language models suffer severe performance degradation when subject to simple lexical constraints like banning a single punctuation mark or common word, losing 14-48% of response quality. This fragility stems from a planning failure where models couple task competence to narrow surface-form templates, affecting both open-weight and commercially deployed closed-weight models like GPT-4o-mini.

Evaluation of Small Language Models for Arabic Language Processing

Researchers evaluated 12 small language models on Arabic NLP tasks using a 240-item benchmark across 8 domains, finding that Gemma 3 (12B) performed best despite model size alone not determining performance. The study reveals that Arabic alignment and instruction-following capability matter more than parameter count, with lower-performing models struggling with prompt leakage, hallucination, and language drift.
