# Qwen3-Embedding-0.6B ONNX INT8 for Text Embeddings Inference
|
49 |
+
|
50 |
+
This is an INT8 quantized ONNX version of [Qwen/Qwen3-Embedding-0.6B](https://huggingface.co/Qwen/Qwen3-Embedding-0.6B) optimized specifically for [Text Embeddings Inference (TEI)](https://github.com/huggingface/text-embeddings-inference) with CPU acceleration.
|
51 |
+
|
52 |
+
## Key Features
|
53 |
+
|
54 |
+
- **INT8 Quantization**: ~8x smaller model size (0.56GB vs 4.7GB)
|
55 |
+
- **CPU Optimized**: 2-4x faster inference on CPU compared to float32
|
56 |
+
- **TEI Compatible**: Properly formatted for Text Embeddings Inference
|
57 |
+
- **Multilingual**: Supports 29 languages including English, Chinese, Russian, Japanese, etc.
|
58 |
+
- **Mean Pooling**: Configured for mean pooling (handled by TEI)
|
59 |
+
|
60 |
+
## Performance
|
61 |
+
|
62 |
+
- **Model size**: 0.56 GB (vs 4.7 GB float32)
|
63 |
+
- **Expected speedup**: 2-4x on CPU
|
64 |
+
- **Accuracy**: Minimal loss (1-3%) compared to float32
|
65 |
+
- **Best for**: CPU deployments, edge devices, high-throughput scenarios
|

## Usage with Text Embeddings Inference
|
68 |
+
|
69 |
+
### Docker Deployment (CPU)
|
70 |
+
|
71 |
+
```bash
|
72 |
+
docker run -p 8080:80 \
|
73 |
+
-e OMP_NUM_THREADS=$(nproc) \
|
74 |
+
-e KMP_AFFINITY=granularity=fine,compact,1,0 \
|
75 |
+
-e ORT_THREAD_POOL_SIZE=$(nproc) \
|
76 |
+
ghcr.io/huggingface/text-embeddings-inference:cpu-latest \
|
77 |
+
--model-id YOUR_USERNAME/qwen3-embedding-0.6b-int8-tei-onnx
|
78 |
+
```
|
79 |
+
|
80 |
+
### Python Client
|
81 |
+
|
82 |
+
```python
|
83 |
+
from huggingface_hub import InferenceClient
|
84 |
+
|
85 |
+
client = InferenceClient("http://localhost:8080")
|
86 |
+
|
87 |
+
# Single embedding
|
88 |
+
response = client.post(
|
89 |
+
json={"inputs": "What is Deep Learning?"},
|
90 |
+
)
|
91 |
+
embedding = response.json()
|
92 |
+
|
93 |
+
# Batch embeddings
|
94 |
+
response = client.post(
|
95 |
+
json={"inputs": ["What is Deep Learning?", "深度学习是什么?"]},
|
96 |
+
)
|
97 |
+
embeddings = response.json()
|
98 |
+
```
|
99 |
+
|
100 |
+
## CPU Optimization
|
101 |
+
|
102 |
+
For optimal CPU performance, set these environment variables:
|
103 |
+
|
104 |
+
```bash
|
105 |
+
export OMP_NUM_THREADS=$(nproc) # Use all physical cores
|
106 |
+
export KMP_AFFINITY=granularity=fine,compact,1,0
|
107 |
+
export ORT_THREAD_POOL_SIZE=$(nproc)
|
108 |
+
```
