-The Agora Conversational AI SDK provides convenient access to the Agora Conversational AI APIs, enabling you to build voice-powered AI agents with support for both cascading flows (ASR -> LLM -> TTS) and multimodal flows (MLLM) for real-time audio processing.
+The Agora Agent Server SDK for Python lets you build real-time voice agents on Agora Conversational AI with a high-level `Agent` / `AgentSession` API and a generated low-level REST client.

+## MLLM (Realtime / Multimodal)
+
+Use `with_mllm()` for OpenAI Realtime or Gemini Live. No STT, LLM, or TTS vendor is needed when MLLM mode is enabled.
+
+```python
+from agora_agent.agentkit import Agent, OpenAIRealtime
+
+agent = Agent(name="realtime-assistant").with_mllm(
+    OpenAIRealtime(
+        api_key=os.environ["OPENAI_API_KEY"],
+        model="gpt-4o-realtime-preview",
+        greeting_message="Hello! Ready to chat.",
+    )
+)
+```
+
+See the [MLLM Flow guide](./docs/guides/mllm-flow.md) for full examples with Gemini Live and Vertex AI.
