Ukrainian RAG system achieves 2nd place in UNLP 2026 Shared Task

Researchers have developed an efficient Retrieval-Augmented Generation (RAG) system tailored for Ukrainian document question answering, securing second place in the UNLP 2026 Shared Task. The system employs a two-stage retrieval process and a specialized Ukrainian language model fine-tuned on synthetic data. Notably, the model is compressed for lightweight, local deployment on resource-constrained hardware without compromising accuracy. AI
