+Multi-Provider Client
+========================
+Async client that routes to different LLM providers based on model name.
+
+Usage:
+  - google-gemini-2.0-flash  → Google API
+  - groq-llama-3.3-70b       → Groq API
+  
+Model name must be in "provider-model" format.
+
+## Usage
+```python
+from agentlightning.utils.multi_provider_ai_client import MultiProviderClient
+client = MultiProviderClient()
+# Use with APO
+algo = agl.APO(
+    client,
+    gradient_model="google-gemini-2.0-flash",
+    apply_edit_model="groq-llama-3.3-70b-versatile",
+)
