xAI 发布 Grok Voice 3.0，语音对话指数 86.9 分登顶
xAI 语音模型接电话能真办事：改签航班成功率 71.6%，比 OpenAI 快 40%，还更便宜。
xAI 发布 Grok Voice 3.0，在 Artificial Analysis 的 Speech-to-Speech Index 拿下 86.9 分，超过 OpenAI GPT-Live-1 的 83.2 分。该指数综合口语推理、模拟客服通话、盲测投票和任务完成率四类指标。提升最大的是 τ-Voice 基准：模拟来电要求模型改签航班或争议扣款，成功率从 Grok Voice 2.0 的 56.5% 升至 71.6%。响应约 0.8 秒，比 GPT-Live-1 的 1.34 秒快约 40%，略慢于上一代的 0.70 秒。成本上 Big Bench Audio 每任务 $0.025，低于 GPT-Live-1 的 $0.030 和 GPT-Realtime-2.1 (High) 的 $0.055。
SpaceXAI launched Grok Voice 3.0
tops Artificial Analysis’s Speech-to-Speech Index at 86.9, beating OpenAI and Google.
The index blends spoken reasoning, simulated support calls, blind preference votes and task success, where GPT-Live-1 (Astra, Medium) reaches 83.2.
The largest gain comes on τ-Voice, where a simulated caller asks the model to rebook flights or dispute charges using domain tools and a policy document.
There, Grok’s success rate jumped from 56.5% under Grok Voice 2.0 to 71.6%.
Grok’s edge is speed: it answers 40% sooner than GPT-Live-1, whose 1.34 seconds implies roughly 0.8 seconds, slightly slower than Grok Voice 2.0’s 0.70. Introducing Grok Voice 3.0 +2
It also costs $0.025 per task on Artificial Analysis’s Big Bench Audio run, against $0.030 for GPT-Live-1 and $0.055 for GPT-Realtime-2.1 (High).
