Realtime models

Connect to wss://my.orq.ai/v3/router/realtime?model=xai/grok-voice-3.0 with an Authorization: Bearer $ORQ_API_KEY header. Use xai/grok-voice-latest to follow the latest Grok Voice version. Grok Voice forwards JSON events and binary audio frames. Use client-executed function tools; provider-hosted tools, switching models within a session, nonempty response.create.input overrides, and items mixing audio with other content are rejected. For PCM audio, send raw PCM16; WAV and AIFF containers are rejected. Grok Voice audio costs 0.08perminute.With‘servervad‘,billingmeasureselapsedtimefromthefirstaudiountilthesessionends;manualturndetectionmetersthesumofaudiosentandreceived.Each‘conversation.item.create‘eventwithoutaudiocosts0.08 per minute. With `server_vad`, billing measures elapsed time from the first audio until the session ends; manual turn detection meters the sum of audio sent and received. Each `conversation.item.create` event without audio costs 0.004, except function_call_output items. Sessions end after 120 minutes. See xAI speech pricing.
