Proceed with caution

Why: Grok Voice 3.0 is available as the default Speech to Speech model, holds the top Speech to Speech Index entry (86.9 vs 83.2 for GPT-Live-1) on the Artificial Analysis page, and costs a flat $0.08/min with voice cloning and 20+ languages. The evidence is largely vendor-cited, latency regressed against 2.0, no weights release is mentioned, and session and concurrency limits are not stated on the Voice Agent page, so it is a strong candidate that warrants a bake-off on the intended workload rather than a blind switch.
Next: Run a side-by-side pilot of grok-voice-3.0 against GPT-Live-1 and Gemini 3.8 Live on your own task set, measuring time to first audio, tool-call reliability, language accuracy and cost per task, and confirm session and rate limits with xAI before committing.
