# Embeddings
|
|
GPT4All supports generating high quality embeddings of arbitrary length documents of text using a CPU optimized contrastively trained [Sentence Transformer](https://www.sbert.net/). These embeddings are comparable in quality for many tasks with OpenAI.
|
|
|
|
## Quickstart
|
|
|
|
```bash
|
|
pip install gpt4all
|
|
```
|
|
|
|
### Generating embeddings
|
|
The embedding model will automatically be downloaded if not installed.
|
|
|
|
=== "Embed4All Example"
|
|
``` py
|
|
from gpt4all import GPT4All, Embed4All
|
|
text = 'The quick brown fox jumps over the lazy dog'
|
|
embedder = Embed4All()
|
|
output = embedder.embed(text)
|
|
print(output)
|
|
```
|
|
=== "Output"
|
|
```
|
|
[0.034696947783231735, -0.07192722707986832, 0.06923297047615051, ...]
|
|
```
|
|
### Speed of embedding generation
