For years, we’ve had to make a trade-off using cloud-based apparatus like Google Translate or DeepL, or choosing open-source, privacy-friendly apparatus that didn’t all the time send the identical top of the range.
Fortunately, with the short trends in AI and system finding out, that trade-off isn’t essential.
Enter LTEngine.

LTEngine is a powerful, AI-powered support for the most well liked LibreTranslate problem. It’ll give you the identical complicated translation top of the range you’d expect from major industry products and services and merchandise, on the other hand with one key difference: the whole thing runs in the neighborhood, correct for your computer.
A really perfect tool for many who price privacy while nevertheless in need of high-quality translations for commerce forms, personal messages, or some other text.
Let’s see the way you’ll be capable to make this artwork.
Pre-requisites
At the time of this writing, LTEngine is still in full of life development. There isn’t a single binary that shall we arrange however, so the following prerequisites are required to organize your setting:
- Rust: The primary language of the LTEngine server.
- Clang: A C/C++ frontend compiler for development the native dependencies.
- CMake: A cross-platform assemble software used to configure the native assemble process.
- A C++ Compiler: Each g++ (Linux/macOS) or MSVC (House home windows) for the entire compilation of the native bindings.
To check if the ones apparatus are already installed, open your terminal or command suggested and run the directions listed below.
| Tool | Check out Command | Arrange Recommendation |
|---|---|---|
| Rust | rustc --version |
Arrange by the use of rustup. That’s the recommended toolchain manager for all platforms. |
| Clang | clang --version |
On Linux, run sudo apt arrange build-essential clang. On macOS, you’ll wish to run xcode-select --install. On House home windows, arrange the Desktop development with C++ workload throughout the Visual Studio Assemble Equipment installer. |
| CMake | cmake --version |
On Linux, run sudo apt arrange cmake. On macOS, you’ll wish to run brew arrange cmake. On House home windows, arrange CMake by the use of the legitimate installer. |
While you download a version amount for each tool, you’re good to go!
Arrange
With the prerequisites in place, we can now proceed to position in LTEngine.
First, we wish to clone the repository:
git clone https://github.com/LibreTranslate/LTEngine --recursive
Then, cross to the record:
cd LTEngine
Next, we wish to assemble the problem. Depending for your software’s GPU, you’ll be capable to make a choice one of the crucial essential following directions:
# For Metal (macOS) cargo assemble --features metal --release # For CUDA and Vulkan (Linux/House home windows) cargo assemble --features cuda,vulkan --release
This process would most likely take some time as it compiles the essential parts. As quickly because it’s accomplished, the compiled binary may well be situated throughout the purpose/release record.
Now, we can run the server by way of executing the binary built:
./purpose/release/ltengine
LTEngine is helping Gemma3 out of the sector. You’ll be capable to pass the -m parameter to acquire the kind, as an example:
./purpose/release/ltengine -m gemma3-1b
This will likely most likely download the Gemma3 1B kind, which is a tiny kind suitable for testing purposes as it calls for far much less computational power and memory, but it surely indisputably lacks the translation top of the range of larger models.
For production use, imagine using higher models like Gemma3 4B or 16B you probably have the essential {{hardware}} assets.
Once the kind is downloaded, you’ll be capable to get began translating text by way of sending requests to the server’s API endpoints at http://localhost:5050/translate.
API Usage
LTEngine provides a RESTful API for translation requests. You’ll be capable to send a POST request to the /translate endpoint with the text you wish to have to translate and the target language, as an example:
curl -X POST "http://localhost:5050/translate" -H "Content material material-Type: device/json" -d '{
"q": "Hello, international!",
"provide": "en",
"purpose": "es"
}'
This request translates “Hello, international!” from English to Spanish. The server will answer with the translated text.
{
"translatedText": "¡Hola, mundo!"
}
Auto Come throughout Language
You’ll be capable to moreover let LTEngine auto-detect the provision language by way of omitting the provide parameter:
curl -X POST "http://localhost:5050/translate" -H "Content material material-Type: device/json" -d '{
"q": "Bonjour le monde!",
"provide": "auto",
"purpose": "en"
}'
This will likely most likely translate “Bonjour le monde!” to English, with the server routinely detecting that the provision language is French. The response may well be:
{
"detectedLanguage": {
"confidence": 85,
"language": "fr"
},
"translatedText": "Hello international!"
}
Wrapping up
At the time of writing, LTEngine is still beneath full of life development, with quite a few exciting issues on the roadmap. One who I’m particularly having a look forward to is record translation, ideally with make stronger for not unusual formats like DOCX and PDF.
Even so, LTEngine already delivers high-quality, AI-powered translations all operating in the neighborhood for your system.
With its API endpoint, you’ll be capable to even assemble your own translation apparatus or apps while conserving all wisdom processing local and protected. This means your wisdom stays non-public, protected, and completely beneath your control.
