Language on Demand, Knowledge at Core: Composing LLMs with Encoder-Decoder Translation Models for Extensible Multilinguality

Dimensions overall score 7.0

• XBridge enhances multilingual capabilities of LLMs by integrating pretrained encoder-decoder translation models for improved performance on low-resource languages. Although LLMs encode substantial cross-lingual knowledge in a unified semantic space, they often struggle to reliably interface this knowledge with low-resource or unseen languages.problem 35%

• ScienceToStartup currently rates this 7.0/10 on the public viability pass. Experiments on four LLMs across multilingual understanding, reasoning, summarization, and generation indicate that XBridge outperforms strong baselines, especially on low-resource and previously unseen languages, without retraining the LLM. A public repository is linked, so build verification can inspect implementation evidence instead of treating the paper as PDF-only.result 35%
