# Quickstart
# How to Generate Text Embedings with FastEmbed

## Install FastEmbed
```python
pip install fastembed
```
Just for demo purposes, you will use Lists and NumPy to work with sample data.
```python
from typing import List
import numpy as np
```

## Load default model

In this example, you will use the default text embedding model, `BAAI/bge-small-en-v1.5`. 
```python
from fastembed import TextEmbedding
```

## Add sample data

Now, add two sample documents. Your documents must be in a list, and each document must be a string
```python
documents: List[str] = [
    "FastEmbed is lighter than Transformers & Sentence-Transformers.",
    "FastEmbed is supported by and maintained by Qdrant.",
]
```
Download and initialize the model. Print a message to verify the process.

```python
embedding_model = TextEmbedding()
print("The model BAAI/bge-small-en-v1.5 is ready to use.")
```
## Embed data

Generate embeddings for both documents. 
```python
embeddings_generator = embedding_model.embed(documents)
embeddings_list = list(embeddings_generator)
len(embeddings_list[0])  
```
Here is the sample document list. The default model creates vectors with 384 dimensions.

```bash
Document: This is built to be faster and lighter than other embedding libraries e.g. Transformers, Sentence-Transformers, etc.
Vector of type: <class 'numpy.ndarray'> with shape: (384,)
Document: fastembed is supported by and maintained by Qdrant.
Vector of type: <class 'numpy.ndarray'> with shape: (384,)
```

## Visualize embeddings
```python
print("Embeddings:\n", embeddings_list)
```
The embeddings don't look too interesting, but here is a visual.

```bash
