Hy-MT2 is a multilingual translation model series open-sourced by Tencent Hunyuan. It includes three sizes — Hy-MT2-1.8B, Hy-MT2-7B, and Hy-MT2-30B-A3B — all supporting translation across 33 languages and 5 Chinese ethnic minority / dialect translation pairs. The 30B-A3B uses a MoE architecture (30B total parameters / 3B activated), while the 1.8B and 7B are dense models. Compared to the previous generation Hy-MT1.5, MT2 brings improvements in domain-specific translation, instruction following, and on-device deployment:
The 7B and 30B-A3B achieve 96.9% and 98.1% of Gemini 2.5 Pro's performance respectively on the FLORES-200 general translation benchmark, surpassing open-source models such as DeepSeek-V4-Pro and Kimi K2.6; the 1.8B outperforms leading commercial translation APIs overall.
The 30B-A3B achieves a GEMBA score of 99.0% of Gemini 2.5 Pro's on the DomainMTBench benchmark across vertical domains including finance, politics, and education.
Supports translation instructions such as glossary/terminology control, style transformation, and structured output (HTML/JSON), with instruction-following capability exceeding open-source models of the same size.
The 1.8B offers a 1.25-bit quantized version based on the Sherry framework, requiring only ~440 MB of storage, enabling local inference on mobile chips from Apple, Qualcomm, MediaTek, and others.

Technical Overview
FlagOS is a fully open-source system software stack designed to unify the "model–system–chip" layers and foster an open, collaborative ecosystem. It enables a "develop once, run anywhere" workflow across diverse AI accelerators, unlocking hardware performance, eliminating fragmentation among vendor-specific software stacks, and substantially lowering the cost of porting and maintaining AI workloads. With core technologies such as the FlagScale, together with vllm-plugin-fl, distributed training/inference framework, FlagGems universal operator library, FlagCX communication library, and FlagTree unified compiler, the FlagRelease platform leverages the FlagOS stack to automatically produce and release various combinations of <chip + open-source model>. This enables efficient and automated model migration across diverse chips, opening a new chapter for large model deployment and application.
FlagGems
FlagGems is a high-performance, generic operator library implemented in Triton language. It is built on a collection of backend-neutral kernels that aims to accelerate LLM (Large-Language Models) training and inference across diverse hardware platforms.
FlagTree
FlagTree is an open source, unified compiler for multiple AI chips project dedicated to developing a diverse ecosystem of AI chip compilers and related tooling platforms, thereby fostering and strengthening the upstream and downstream Triton ecosystem. Currently in its initial phase, the project aims to maintain compatibility with existing adaptation solutions while unifying the codebase to rapidly implement single-repository multi-backend support. For upstream model users, it provides unified compilation capabilities across multiple backends; for downstream chip manufacturers, it offers examples of Triton ecosystem integration.
FlagScale and vllm-plugin-fl
Flagscale is a comprehensive toolkit designed to support the entire lifecycle of large models. It builds on the strengths of several prominent open-source projects, including Megatron-LM and vLLM, to provide a robust, end-to-end solution for managing and scaling large models.
vllm-plugin-fl is a vLLM plugin built on the FlagOS unified multi-chip backend, to help flagscale support multi-chip on vllm framework.
FlagCX
FlagCX is a scalable and adaptive cross-chip communication library. It serves as a platform where developers, researchers, and AI engineers can collaborate on various projects, contribute to the development of cutting-edge AI solutions, and share their work with the global community.
FlagEval Evaluation Framework
FlagEval is a comprehensive evaluation system and open platform for large models launched in 2023. It aims to establish scientific, fair, and open benchmarks, methodologies, and tools to help researchers assess model and training algorithm performance. It features:
Multi-dimensional Evaluation: Supports 800+ model evaluations across NLP, CV, Audio, and Multimodal fields, covering 20+ downstream tasks including language understanding and image-text generation.
Industry-Grade Use Cases: Has completed horizontal evaluations of mainstream large models, providing authoritative benchmarks for chip-model performance validation.
