# Zen Embedding 8B

8B-parameter text-embedding model for retrieval-augmented generation, semantic search, and dense retrieval. Part of the Zen embedding line.

Repackaged from [Qwen/Qwen3-Embedding-8B](https://huggingface.co/Qwen/Qwen3-Embedding-8B) (apache-2.0, Alibaba Qwen). Native HuggingFace `safetensors`, re-hosted under the Zen embedding line. **Not trained from scratch** — a permissively-licensed redistribution for the OSS-clean Zen model line.

## Usage

```python
from sentence_transformers import SentenceTransformer

model = SentenceTransformer("zenlm/zen-embedding-8B")
emb = model.encode(["The weather is lovely today.", "It's so sunny outside!"])
print(model.similarity(emb, emb))
```

Hosted via the Hanzo gateway (`api.hanzo.ai`) as `zen-embedding-8b`.

GGUF build for CPU inference: [zenlm/zen-embedding-8B-GGUF](https://huggingface.co/zenlm/zen-embedding-8B-GGUF).
