+
+The fastest way to use v5-text in production. Elastic Inference Service (EIS) provides managed embedding inference with built-in scaling, so you can generate embeddings directly within your Elastic deployment.
+
+```bash
+PUT _inference/text_embedding/jina-v5
+{
+  "service": "elastic",
+  "service_settings": {
+    "model_id": "jina-embeddings-v5-text-nano"
+  }
+}
+```
+
+See the [Elastic Inference Service documentation](https://www.elastic.co/docs/explore-analyze/elastic-inference/eis) for setup details.
