  abstract  = {We describe the PSK submission to the WMT 2026 Multilingual Instruction Shared Task. Our system uses the 3.35B-parameter Tiny Aya Global model with three QLoRA adapters, one for each task. The adapters are trained on multilingual document–summary pairs, passage-based question answering, and filtered standalone question answering. The summarization data also includes scientific papers with their author-written abstracts. On our held-out split, the context and summarization adapters perform better than our multitask adapter, while results for open QA are mixed. Official evaluation ranks PSK sixth overall and fourth for summarization. Context QA and open QA remain weaker, and the multitask open-QA route outperforms both specialized open-QA adapters.},
