Model Introduction

The Hunyuan Translation Model comprises a translation model, Hunyuan-MT-7B, and an ensemble model, Hunyuan-MT-Chimera. The translation model is used to translate source text into the target language, while the ensemble model integrates multiple translation outputs to produce a higher-quality result. It primarily supports mutual translation among 33 languages, including five ethnic minority languages in China.

Key Features and Advantages

In the WMT25 competition, the model achieved first place in 30 out of the 31 language categories it participated in.
Hunyuan-MT-7B achieves industry-leading performance among models of comparable scale
Hunyuan-MT-Chimera-7B is the industry’s first open-source translation ensemble model, elevating translation quality to a new level
A comprehensive training framework for translation models has been proposed, spanning from pretrain → cross-lingual pretraining (CPT) → supervised fine-tuning (SFT) → translation enhancement → ensemble refinement, achieving state-of-the-art (SOTA) results for models of similar size

Prompts

Prompt Template for ZH<=>XX Translation.


把下面的文本翻译成<target_language>，不要额外解释。

<source_text>

Prompt Template for XX<=>XX Translation, excluding ZH<=>XX.


Translate the following segment into <target_language>, without additional explanation.

<source_text>

Prompt Template for Hunyuan-MT-Chimera-7B-AWQ


Analyze the following multiple <target_language> translations of the <source_language> segment surrounded in triple backticks and generate a single refined <target_language> translation. Only output the refined translation, do not explain.

The <source_language> segment:
```<source_text>```

The multiple <target_language> translations:
1. ```<translated_text1>```
2. ```<translated_text2>```
3. ```<translated_text3>```
4. ```<translated_text4>```
5. ```<translated_text5>```
6. ```<translated_text6>```

Use with transformers

First, please install transformers, recommends v4.56.0

pip install transformers==4.56.0

The following code snippet shows how to use the transformers library to load and apply the model.

!!! If you want to load fp8 model with transformers, you need to change the name"ignored_layers" in config.json to "ignore" and upgrade the compressed-tensors to compressed-tensors-0.11.0.

we use shawnw3i/Hunyuan-MT-Chimera-7B-AWQ for example

python

from transformers import AutoModelForCausalLM, AutoTokenizer
import os

model_name_or_path = "shawnw3i/Hunyuan-MT-Chimera-7B-AWQ"

tokenizer = AutoTokenizer.from_pretrained(model_name_or_path)
model = AutoModelForCausalLM.from_pretrained(model_name_or_path, device_map="auto")  # You may want to use bfloat16 and/or move to GPU here
messages = [
    {"role": "user", "content": "Translate the following segment into Chinese, without additional explanation.\n\nIt’s on the house."},
]
tokenized_chat = tokenizer.apply_chat_template(
    messages,
    tokenize=True
    add_generation_prompt=False,
    return_tensors="pt"
)

outputs = model.generate(tokenized_chat.to(model.device), max_new_tokens=2048)
output_text = tokenizer.decode(outputs[0])

Use with vLLM

pip install vllm --upgrade

vllm serve shawnw3i/Hunyuan-MT-Chimera-7B-AWQ

We recommend using the following set of parameters for inference. Note that our model does not have the default system_prompt.

json

{
  "top_k": 20,
  "top_p": 0.6,
  "repetition_penalty": 1.05,
  "temperature": 0.7
}
