…-think-fast-1.0 x.ai deprecated grok-voice-fast-1.0 and recommends grok-voice-think-fast-1.0 as the new flagship voice model, selectable via the model query param on the realtime websocket. The parent OpenAI realtime client already forwards model as a ws query param, so the resulting URL matches the x.ai docs exactly. Adds a GrokRealtimeModels literal with both the new and legacy ids, updates the default to grok-voice-think-fast-1.0, and types the model option as GrokRealtimeModels | string. Port of livekit/agents#5548. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
