arXiv:2604.11290v2 Announce Type: replace Abstract: Synthesizing supervised finetuning (SFT) data from language models (LMs) to teach smaller models multilingual tasks has become increasingly common. However, teacher model selection is often ad hoc, typically defaulting to the largest available option, even though such models may have significant capability gaps in non-English languages. This practice can result in poor-quality synthetic data and suboptimal student downstream performance. In this work, we systematically characterize what makes an effective multilingual teacher. We measure intr
The proliferation of language models and increasing demand for multilingual AI capabilities are driving research into efficient and effective synthetic data generation.
This research provides a systematic approach to selecting 'teacher' models for multilingual synthetic data, which is crucial for developing robust, non-English AI and reducing biases inherent in current English-centric models.
The focus shifts from simply using the largest available language model to a more nuanced, capability-based selection for multilingual synthetic data generation, improving the quality and performance of AI in diverse linguistic contexts.
