 ## Run the agent
 
-Before your first run, you must download certain models such as [Silero VAD](https://docs.livekit.io/agents/logic/turns/vad/) and the [LiveKit turn detector](https://docs.livekit.io/agents/logic/turns/turn-detector/):
+Before your first run, download the [ai-coustics noise cancellation](https://docs.livekit.io/transport/media/noise-cancellation/) model used by the agent:
 
 ```console
-uv run python src/agent.py download-files
+uv run --module livekit.agents download-files
 ```
 
+The [LiveKit turn detector](https://docs.livekit.io/agents/logic/turns/turn-detector/) and the agent's voice activity detection both run on [LiveKit Inference](https://docs.livekit.io/agents/models/inference) and are built into the Agents SDK, so they don't require a separate download.
+
 Next, run this command to speak to your agent directly in your terminal:
 
 ```console
