# Zen3 Embedding Medium
Medium-sized Zen3 embedding model balancing speed and retrieval accuracy.
## Overview
Built on **Zen MoDE (Mixture of Distilled Experts)** architecture with medium parameters and 8K context window.
Developed by [Hanzo AI](https://hanzo.ai) and the [Zoo Labs Foundation](https://zoo.ngo).
## Quick Start
```python
from sentence_transformers import SentenceTransformer
model = SentenceTransformer("zenlm/zen3-embedding-medium")
sentences = [
"The weather is lovely today.",
"It's so sunny outside!",
"He drove to the stadium.",
]
embeddings = model.encode(sentences)
print(embeddings.shape)
# Compute cosine similarities
similarities = model.similarity(embeddings, embeddings)
print(similarities)
```
## API Access
```python
from openai import OpenAI
client = OpenAI(base_url="https://api.hanzo.ai/v1", api_key="your-api-key")
response = client.embeddings.create(model="zen3-embedding-medium", input="Your text here")
print(response.data[0].embedding)
```
