xAI 发布 Grok Voice 3.0 语音到语音模型,Voice Agent API 每分钟 0.08 美元
xAI 于 10 月 14 日发布 Grok Voice 3.0 语音到语音模型,已在 Voice Agent API 上线,定价每分钟 0.08 美元,与上一代相同。xAI 引用 Artificial Analysis 10 月 13 日的独立测试称,该模型以 86.9 分位列 Speech-to-Speech Index 第一,高于 GPT-Live-1(Astra, Medium)的 83.2 和 Gemini 3.8 Live 的 82.6,延迟低于一秒。xAI 还称其在 ServiceNow 的 EVA-Bench 上取得 74% 的最高准确率,并已在 Tesla 车辆和 Starlink 呼叫中心部署,后者每天处理 2 万通客户来电。
sts GPT-Live-1 (Astra, Medium) at 74.5%, Gemini 3.8 Live (Extended Thinking, High) at 68.6%, and Grok Voice 2.0 at 56.5%. xAI also reported that Artificial Analysis measured an average cost per task on its Big Bench Audio run of $0.025 for Grok Voice 3.0, compared with $0.030 for GPT-Live-1 (Astra, Medium) and $0.055 for GPT-Realtime-2.1 (High). Artificial Analysis defines its Speech-to-Speech Index as an equal-weighted score across four components: speech reasoning from Big Bench Audio, agentic
