This [Model2Vec](https://github.com/MinishLab/model2vec) model is a distilled version of the unknown(https://huggingface.co/unknown) Sentence Transformer. It uses static embeddings, allowing text embeddings to be computed orders of magnitude faster on both GPU and CPU. It is designed for applications where computational resources are limited or where real-time performance is critical. Model2Vec models are the smallest, fastest, and most performant static embedders available. The distilled models are up to 50 times smaller and 500 times faster than traditional Sentence Transformers.

-
### Using Model2Vec
|
| 27 |
-
|
| 28 |
-
The [Model2Vec library](https://github.com/MinishLab/model2vec) is the fastest and most lightweight way to run Model2Vec models.
|
| 29 |
-
|
| 30 |
-
Load this model using the `from_pretrained` method:
|
| 31 |
```python
|
| 32 |
-
from model2vec import

# Distill a Sentence Transformer model, in this case the BAAI/bge-base-en-v1.5 model

## How it works

|
|
|
|
|
|
|
|
|
|
|
|
|
|

|
| 73 |
-
It works by passing a vocabulary through a sentence transformer model, then reducing the dimensionality of the resulting embeddings using PCA, and finally weighting the embeddings using [SIF weighting](https://openreview.net/pdf?id=SyK00v5xx). During inference, we simply take the mean of all token embeddings occurring in a sentence.
