OpenBracket submits constrained systems to both English-paired directions of the WMT 2026 Low-Resource Arabic-Asian Language Translation task, trained on the official data only (21,000 pairs) from publicly available checkpoints. Per direction we submit a primary COMET-22 MBR system combination over five fine-tuned models (NLLB-3.3B, two X-ALMA variants, ALLaM-7B, OPUS-MT) plus two contrastive systems: an ALLaM-7B fine-tune and sampling-based MBR over NLLB-3.3B. On the official test set, our primary ranks first among all teams in Arabic-to-English (BLEU 33.83, chrF 59.72, TER 57.00, COMET 82.49), and in English-to-Arabic it attains the highest COMET on the primary leaderboard (BLEU 21.81, chrF 54.99, TER 69.29, COMET 85.23).
