The system addresses the persistent generation bottleneck where models can understand many languages but fail to generate them reliably. OMT uses a comprehensive data strategy combining public multilingual corpora, manually curated MeDLEY bitext, synthetic backtranslation, and mining. Two model variants are introduced: OMT-LLaMA (decoder-only, built on LLaMA3 with retrieval-augmented translation) and OMT-NLLB (encoder-decoder architecture using OmniSONAR embeddings). Notably, 1B–8B parameter OMT models match or exceed a 70B LLM baseline on MT tasks, demonstrating a clear specialization advantage. New evaluation artifacts include BLASER 3, OmniTOX, and the BOUQuET multilingual evaluation dataset. The BOUQuET and Met-BOUQuET datasets are freely available. ## Full article daily.dev links to this article rather than hosting it.
