On the Robustness of Multilingual Text Embedding Rankings Across Learning Tasks, Languages, and Benchmark Datasets
arXiv:2605.31142v1 Announce Type: cross Abstract: Large-scale multilingual text embedding models play crucial role in both research and industry, yet their behavior in language-specific, multi-task settings remains insufficiently understood. Although benchmarking platforms such as MTEB report results across more than 250 languages, conclusions about model superiority often depend on implicit choices of dataset compositions and performance aggregation methods. To address this gap, we present a meta-study of multilingual model performance robustness in MTEB, applying a diverse set of multi-crite
The proliferation of sophisticated multilingual large language models necessitates a deeper understanding of their robustness and performance across diverse linguistic landscapes.
This research provides critical insights into the reliability and generalizability of multilingual AI models, directly impacting their deployment and trust in global applications.
Our understanding of the true capabilities and limitations of multilingual text embeddings across various tasks and languages is refined, highlighting potential biases or inconsistencies.
