๐๐๐We are excited to open-source Tencent-HY-MT1.5, featuring two translation modelsโ1.8B and 7Bโdesigned for seamless on-device and cloud deployment with industry-leading speed and accuracy. Highlights: ๐น 1.8B On-Device Power: Optimized for consumer hardware with a 1GB memory footprint. Using on-policy distillation to align with larger models, it delivers 0.18s latency (50 tokens), outperforming mainstream commercial APIs. ๐น 7B SOTA Performance: An upgraded version of our WMT25 champion, surpassing mid-sized open-source models and rivaling the 90th percentile of closed-source giants like Gemini-3.0-Pro. ๐น 33+ Languages & Dialects: High-fidelity translation across 33 languages and 5 Chinese dialects. ๐น Production-Ready: Native support for custom terminology, long-dialogue context, and maintaining document formatting. Already powering multiple Tencent services, our dual-model synergy ensures consistent and stable performance across both on-device and cloud environments. ๐ ๐๐ป Try it now: https://t.co/MOGj8Uwzwu ๐ GitHub: https://t.co/a65YZGBj7B ๐ค Hugging Face: https://t.co/EJJQM4x7EZ
