Edge Deployment of HY-MT1.5-1.8B

Introduction

HY-MT1.5-1.8B is the 1.5 version of the Hunyuan translation model released by Tencent. As an upgraded version of the WMT25 championship model, it is optimized for explanatory translation and mixed-language scenarios, and adds support for terminology intervention, contextual translation, and formatted translation. Although HY-MT1.5-1.8B has less than one-third the parameter count of HY-MT1.5-7B, its translation performance is comparable to that of the larger model, balancing high speed with high quality. After quantization, the 1.8B model can be deployed on edge devices and supports real-time translation scenarios, offering broad application prospects.

This chapter demonstrates how to perform HY-MT1.5-1.8B deployment, loading, and translation on edge devices. Two deployment methods are provided:

AidGen C++ API
AidGenSE OpenAI API

In this case, the large language model inference runs on the device side, and the relevant interfaces are called through code to receive user input and return conversation results in real time.

Device: Rhino Pi-X1
System: Ubuntu 22.04
Model: HY-MT1.5-1.8B

Supported Platforms

Platform	Running Method
Rhino Pi-X1	Ubuntu 22.04, AidLux

Preparation

Rhino Pi-X1 hardware
Ubuntu 22.04 system or AidLux system

AidGen Case Deployment

Step 1: Install the AidGen SDK

bash

# Install AidGen SDK
sudo aid-pkg update
sudo aid-pkg -i aidgen-sdk
sudo aid-pkg -i aidgen-qnn236
sudo aid-pkg -i aidgen-qnn240

# Copy test code
cd /home/aidlux/aidllm

cp -r /usr/local/share/aidgen/examples/ ./

Step 2: Download Model Resources

Since HY-MT1.5-1.8B is currently in the Model Farm preview section, it must be retrieved via the mms command.

bash

# Log in
mms login

# Search for the model
mms list HY

# Download the model
mms get -m HY-MT1.5-1.8B -p w4a16 -c qcs8550 -b qnn2.36 -d /home/aidlux/aidllm/hy-mt

cd /home/aidlux/aidllm/hy-mt
unzip qnn236_qcs8550_cl2048.zip
mv qnn236_qcs8550_cl2048/* /home/aidlux/aidllm

Step 3: Create the Configuration File

bash

cd /home/aidlux/aidllm
vim hy-mt-aidgen-config.json

Create the following json configuration file:

json

{
    "backend_type": "genie",
    "prefix_path": "kv-cache.primary.qnn-htp",
    "model": {
        "path": [
            "hy-mt1.5-1.8b_qnn236_qcs8550_cl2048_1_of_2.serialized.bin.aidem",
            "hy-mt1.5-1.8b_qnn236_qcs8550_cl2048_2_of_2.serialized.bin.aidem"
        ]
    }
}

Step 4: Confirm Resource Files

The file distribution is as follows:

bash

/home/aidlux/aidllm
├── aidgen_chat_template.txt
├── chat.txt
├── htp_backend_ext_config.json
├── hy-mt1.5-1.8b-htp.json
├── hy-mt-aidgen-config.json
├── kv-cache.primary.qnn-htp
├── hy-mt1.5-1.8b-tokenizer.json
├── hy-mt1.5-1.8b_qnn236_qcs8550_cl2048_1_of_2.serialized.bin.aidem
├── hy-mt1.5-1.8b_qnn236_qcs8550_cl2048_2_of_2.serialized.bin.aidem
├── examples

Step 5: Set the Conversation Template

💡Note

For the conversation template, refer to the aidgen_chat_template.txt file in the model resource package.

Modify the test_aidgen_text.cpp file according to the large model's template:

cpp

std::string system_prompt =
    "<｜hy_begin▁of▁sentence｜><｜hy_place▁holder▁no▁3｜>\n"
    "<｜hy_begin▁of▁sentence｜>\n"
    "<｜hy_User｜>Translate the following segment into Chinese, without additional explanation.\n\n";
// User turn: wraps the user input and triggers assistant generation
auto make_user_turn = [](const std::string& text) -> std::string {
return text + "\n<｜hy_Assistant｜>";
};

Step 6: Compile and Run

bash

# Install dependencies
cd /home/aidlux/aidllm/examples

# Compile
mkdir build && cd build
cmake .. && make

mv test_text_only /home/aidlux/aidllm/

cd /home/aidlux/aidllm/
./test_text_only hy-mt-aidgen-config.json "Success is not final, failure is not fatal: it is the courage to continue that counts. Believe in yourself and all that you are, for greatness lives within your soul."

AidGenSE Case Deployment

Step 1: Install AidGenSE

bash

sudo aid-pkg update

# Ensure aidgense is the latest version
sudo aid-pkg remove aidgense
sudo aid-pkg -i aidgense
sudo aid-pkg -i aidgen-sdk
sudo aid-pkg -i aidgen-qnn236
sudo aid-pkg -i aidgen-qnn240

Step 2: Model Query & Retrieval

bash

# View models
aidllm remote-list api | grep hy

#------------------------ You can see the HY-MT1.5-1.8B model ------------------------

Current Soc : 8550

# Download HY-MT1.5-1.8B

aidllm pull api aplux/hy-mt1.5-1.8b-qnn2.36-w4a16-qcs8550

Step 3: Start the HTTP Service

bash

# Start the OpenAI API service for the corresponding model
aidllm start api -m hy-mt1.5-1.8b-qnn2.36-w4a16-qcs8550

# Check status
aidllm status api

# Stop service: aidllm stop api

# Restart service: aidllm restart api

💡Note

The default port is 8888.

Step 4: Chat Test

Chat Test via Web UI

bash

# Install UI frontend service
sudo aidllm install ui

# Start UI service
aidllm start ui

# Check UI service status: aidllm status ui

# Stop UI service: aidllm stop ui

After the UI service starts, visit http://ip:51104.

Enter the following conversation template to perform translation:

plain

Translate the following segment into Chinese, without additional explanation.

Success is not final, failure is not fatal: it is the courage to continue that counts. Believe in yourself and all that you are, for greatness lives within your soul.
