# 🧠 Unified Multilingual Distiluse Text Embedder (ONNX + Tokenizer Merged)

This is a highly optimized, quantized, and fully standalone model for **generating sentence embeddings** from **multilingual text**, including Ukrainian, English, Polish, and more.

Built upon `distiluse-base-multilingual-cased-v2`, the model has been:

- 🔁 **Merged with its tokenizer** into a single ONNX file
- ⚙️ **Extended with a custom preprocessing layer**
- ⚡ **Quantized to INT8** and ARM64-ready
- 🧪 **Extensively tested across real-world NLP tasks**
- 🛠️ **Bug-fixed** vs the original `sentence-transformers` quantized version that produced inaccurate cosine similarity

---

## 🚀 Key Features

- 🧩 **Single-file architecture**: no need for external tokenizer, vocab, or `transformers` library.
- ⚡ **93% faster inference** on mobile compared to the original model.
- 🗣️ **Multilingual**: robust across many languages, including low-resource ones.
- 🧠 **Output = pure embeddings**: pass a string, get a 768-dim vector. That’s it.
- 🛠️ **Ready for production**: small, fast, accurate, and easy to integrate.
- 📱 **Ideal for edge-AI, mobile, and offline scenarios.**

## 🐍 Python Example
```python
import numpy as np
import onnxruntime as ort
from onnxruntime_extensions import get_library_path

sess_options = ort.SessionOptions()
sess_options.register_custom_ops_library(get_library_path())

session = ort.InferenceSession(
    'model.onnx',
    sess_options=sess_options,
    providers=['CPUExecutionProvider']
)

input_feed = {"text": np.asarray(['something..'])}
outputs = session.run(None, input_feed)
embedding = outputs[0]
```

---

## 🐍 JS Example
```JavaScript
const session = await InferenceSession.create(EMBEDDING_FULL_MODEL_PATH); 
const inputTensor = new Tensor('string', ['something..'], [1]); 
const feeds = { text: inputTensor };
const outputMap = await session.run(feeds);
const embedding = outputMap.text_embedding.data;
