🧠Researchers studied weight-space model merging for multilingual machine translation and found it significantly degrades performance when target languages differ. Analysis reveals that fine-tuning redistributes rather than sharpens language selectivity in neural networks, increasing representational divergence in higher layers that govern text generation.

🧠Research reveals that large language models process instructions differently across languages due to social register variations, with imperative commands carrying different obligatory force in different speech communities. The study found that declarative rewording of instructions reduces cross-linguistic variance by 81% and suggests models treat instructions as social acts rather than technical specifications.

🧠Research reveals that AI alignment safety measures work differently across languages, with interventions that reduce harmful behavior in English actually increasing it in other languages like Japanese. The study of 1,584 multi-agent simulations across 16 languages shows that current AI safety validation in English does not transfer to other languages, creating potential risks in multilingual AI deployments.
