Hy-MT2-30B-A3B

by Tencent tencent/Hy-MT2-30B-A3B

Hy-MT2-30B-A3B is an open-weight model for translation from Tencent, released under Apache License 2.0. It has 30.1B parameters and a 262,144-token context. At 16-bit it needs about 72.2 GB of GPU memory, which fits on 1x MI300X from $1.85 an hour, at the lowest prices in the SAVRN Index. It draws 23.6k downloads a month.

Model Introduction

Hy-MT2 is a family of “fast-thinking” multilingual translation models designed for complex real-world scenarios. It includes three model sizes: 1.8B, 7B, and 30B-A3B (MoE), all of which support translation among 33 languages and effectively follow translation instructions in multiple languages. For on-device deployment, AngelSlim 1.25-bit extreme quantization reduces the storage requirement of the 1.8B model to only 440 MB and improves inference speed by 1.5x. Multi-dimensional evaluations show that Hy-MT2 delivers outstanding performance across general, real-world business, domain-specific, and instruction-following translation tasks. The 7B and 30B-A3B models outperform open-source models such as DeepSeek-V4-Pro and Kimi K2.6 in fast-thinking mode, while the lightweight 1.8B model also surpasses mainstream commercial APIs from providers such as Microsoft and Doubao overall.

In this release, we also open-source IFMTBench, a benchmark for evaluating translation instruction-following capabilities.

Questions About Hy-MT2-30B-A3B

How much GPU memory does Hy-MT2-30B-A3B need?

About 72.2 GB at 16-bit and 18 GB at 4-bit: the weights (30.1B parameters) plus a working margin. A long context needs more.

What is the cheapest GPU to run Hy-MT2-30B-A3B on?

At 16-bit, 1x MI300X from $1.85 an hour; at 4-bit, 1x MI300X from $1.85 an hour, at the lowest on-demand prices the SAVRN Index lists.

Can I use Hy-MT2-30B-A3B commercially?

Yes. Hy-MT2-30B-A3B is released under Apache License 2.0. The Apache License 2.0 is a permissive open-source license. It permits commercial use, modification and redistribution. It requires keeping the license and copyright notices and any NOTICE file, stating significant changes, and it includes an express patent grant from contributors.

What is Hy-MT2-30B-A3B's context length?

262,144 tokens, from the maximum position embeddings in its published configuration.
