HY-MT1.5-1.8B

Model Description

HY-MT1.5-1.8B is a 1.8B-parameter multilingual neural machine translation model released by Tencent as part of the Hunyuan Translation Model v1.5 series.

The model focuses on high-quality, high-speed translation across 33 major languages plus 5 ethnic/dialect variants, achieving performance comparable to the larger 7B model while remaining lightweight. After quantization, HY-MT1.5-1.8B is suitable for edge and on-device deployment, enabling real-time translation scenarios.

Quickstart

2. Activate your device with your access token:

nexa config set license '<access_token>'

3. Run the model on Qualcomm NPU in one line:

nexa infer NexaAI/LFM2.5-1.2B-npu

Features

• Multilingual translation: supports 36 languages, including Chinese, English, European, Middle Eastern, South Asian, and Southeast Asian languages.

• Small yet strong: industry-leading translation quality among ~2B-parameter models, surpassing many commercial translation APIs.

• Edge-ready: supports FP8 and INT4 quantization for efficient deployment on resource-constrained devices.

• Advanced translation controls:

  • Terminology intervention
  • Context-aware translation
  • Formatted translation with tag preservation

• Robust scenarios: strong performance on mixed-language and explanatory translation tasks.

Use Cases

• Real-time translation on mobile, PC, and edge devices
• Multilingual chat and customer support systems
• Document and webpage translation
• Cross-lingual content creation and localization
• Embedded translation for IoT and smart devices
