-## What's new in GPT Realtime 2.x
+Azure OpenAI bills these models by input, cached input, and output tokens. Image input is billed separately. For current rates, see the **Audio Models** section on the [Azure OpenAI pricing page](https://azure.microsoft.com/pricing/details/cognitive-services/openai-service/).
+
+## GPT Realtime 2.x features
 
 - **Reasoning support** with an adjustable `reasoning.effort` control.
 - **Response phases** that distinguish preambles ("commentary") from the final answer ("final_answer").
 - **Longer context window** (256,000 tokens).
 
 ## Key concepts
 
+### API and transports
+
+Use the GA Realtime API under `/openai/v1`. The WebSocket endpoint has the following format, where the `model` value is your deployment name:
+
+```text
+wss://<resource-name>.openai.azure.com/openai/v1/realtime?model=<deployment-name>
+```
+
+The GA endpoint doesn't use a date-based API version or an `api-version` query parameter. For complete examples, see [Use the GPT Realtime API via WebSockets](/models/realtime-audio-websockets) and [Use the GPT Realtime API via WebRTC](/models/realtime-audio-webrtc).
+
+### Audio and voices
+
+For audio sent as Realtime API events, use headerless, mono PCM16 audio sampled at 24 kHz and base64-encode the bytes. WebRTC negotiates audio transport between the client and service.
+
+The supported output voices are `alloy`, `ash`, `ballad`, `coral`, `cedar`, `echo`, `marin`, `sage`, `shimmer`, and `verse`.
+
 ### Reasoning effort
 
 Control reasoning intensity with the `reasoning.effort` session parameter. Valid values are `minimal`, `low`, `medium`, and `high`.

 Currently, GPT Realtime 2.x models don't support the `truncation` property in the `session.update` payload. To manage token usage and costs in an ongoing conversation, consider using the `conversation.item.truncate` or `conversation.item.delete` events.
 
+Realtime models have separate audio-token and concurrent-session quotas. Review [Azure OpenAI quotas and limits](/models/quotas-limits) before production deployment.

 The connection and usage patterns for GPT Realtime 2.x are the same as for earlier versions. Deploy the new model and point your existing code to it. Choose the transport that fits your scenario:
