xAI just launched its Grok Voice Agent API
xAI just rolled out the Grok Voice Agent API to all developers, bringing the low-latency voice stack powering Tesla cars to third-party apps. It boasts sub-second response times, costs a flat $0.05 per minute, and is fully compatible with OpenAI's Realtime API spec. It can seamlessly switch between dozens of languages mid-sentence and even handle realistic auditory cues like whispers and sighs.
