# OpenAI Embedder

Phidata uses `OpenAIEmbedder` as the default embeder for the vector database. The `OpenAIEmbedder` class is used to embed text data into vectors using the OpenAI API. Get your key from [here](https://platform.openai.com/api-keys).

## Usage

```python cookbook/embedders/openai_embedder.py theme={null}
from phi.agent import AgentKnowledge
from phi.vectordb.pgvector import PgVector
from phi.embedder.openai import OpenAIEmbedder

embeddings = OpenAIEmbedder().get_embedding("Embed me")

# Print the embeddings and their dimensions
print(f"Embeddings: {embeddings[:5]}")
print(f"Dimensions: {len(embeddings)}")

# Example usage:
knowledge_base = AgentKnowledge(
    vector_db=PgVector(
        db_url="postgresql+psycopg://ai:ai@localhost:5532/ai",
        table_name="openai_embeddings",
        embedder=OpenAIEmbedder(),
    ),
    num_documents=2,
)
```
