Qwen-mt-plus is the premier machine translation model in the Qwen family, fully upgraded in late 2025 to the Qwen3 architecture. Trained on trillions of multilingual tokens and fine-tuned with advanced reinforcement learning (RL), it excels in professional translation scenarios requiring high fidelity, such as legal documents, academic papers, and technical reports. It supports 92 major languages and prominent dialects, covering over 95% of the global population. Unlike general-purpose LLMs, it features specialized "Domain Prompting" and "Terminology Intervention," allowing users to upload glossaries to ensure consistent brand or technical wording. Its Mixture-of-Experts (MoE) design ensures cinematic-quality translation with significantly lower latency and cost than flagship dense models.
