+### OrcaRouter
+
+[OrcaRouter](https://www.orcarouter.ai) is an OpenAI-compatible routing gateway that exposes models from OpenAI, Anthropic, Google, DeepSeek, Qwen and others behind a single endpoint and API key. Route embeddings through it with the `openai/` provider prefix and a namespaced model id:
+
+| Model | Model string |
+|-------|-------------|
+| Text Embedding 3 Small | `openai/openai/text-embedding-3-small` |
+| Text Embedding 3 Large | `openai/openai/text-embedding-3-large` |
+
+The outer `openai/` selects the OpenAI-compatible protocol; the inner `openai/…` is the router's namespaced model id. Pass the gateway's base URL and API key directly:
+
+```python
+embedder = LiteLLMEmbedder(
+    "openai/openai/text-embedding-3-small",
+    api_base="https://api.orcarouter.ai/v1",
+    api_key="sk-orca-...",
+)
+```
