Introducing Grok Voice 3.0, the world’s most intelligent speech-to-speech model. It excels at resolving customer calls, responds in under a second, and costs less than other frontier models.

SpaceXAI 的 Grok Voice 3.0 是新的领先语音到语音模型，在 Artificial Analysis 语音到语音指数上以 86.9 首次亮相即排名第 1，同时在延迟方面也很有竞争力 Grok Voice 3.0 是 @SpaceXSI 的 Grok Voice 2.0 的继任者，这是一款可通过 SpaceXAI Realtime API 使用的语音到语音模型，价格为每分钟 $0.08。我们通过 SpaceXAI Realtime API 使用 Rex 语音对 Grok Voice 3.0 进行了评估。 关键要点： ➤ 语音到语音指数：Grok Voice 3.0 以 86.9 首次亮相即排名第 1，领先于 GPT-Live-1（Astra，medium）的 83.2、Gemini 3.8 Live Extended Thinking（High）的 82.6 和 GPT-Live-1（Sol，low）的 80.1。它高于 Grok Voice 2.0 的 81.3（+5.6 分）和 Grok Voice 1.0 的 73.7（+13.2 分），后者发布至今还不到六个月。该指数平均了语音推理（Big Bench Audio）、智能体性能（Tau Voice）、Arena 偏好和任务成功率 ➤ 语音智能体 Arena：Grok Voice 3.0 在偏好方面以 Elo 1070 排名第 3，落后于 Gemini 3.1 Flash Live Minimal（1100）和 Gemini 3.8 Live（1088），领先于 GPT-Live-1（Sol，low）的 1057，并以 94.8% 的任务成功率排名第 1，为榜单最高，略高于 Grok Voice 2.0 的 94.6%。Grok Voice 2.0 以 Elo 1011 落后 ➤ Tau Voice：Grok Voice 3.0 在我们实现的 Tau Voice 基准上以 71.6% 排名第 2，落后于 GPT-Live-1（Astra，medium）的 74.5%，领先于 Gemini 3.8 Live Extended Thinking（High）的 68.6% 和 GPT-Live-1（Sol，low）的 59.3%——高于 Grok Voice 2.0 的 56.5% ➤ Big Bench Audio：Grok Voice 3.0 在音频推理上得分 98.5%，领先于 Gemini 3.8 Live Extended Thinking（High）的 97.7% 和 Grok Voice 2.0 的 97.2% ➤ 速度：在 Big Bench Audio 上，Grok Voice 3.0 的平均首次音频时间为 0.81 秒，明显领先于 GPT-Live-1（Sol，low）的 1.24 秒、GPT-Live-1（Astra，medium）的 1.34 秒和 Gemini 3.8 Live Extended Thinking（High）的 1.35 秒，但慢于 Grok Voice 2.0 的 0.70 秒 ➤ 成本：Grok Voice 3.0 的输入音频成本为每小时 $4.80，与 Grok Voice 2.0 相同。这高于 GPT-Live-1（Sol，low）的 $4.47 和 Gemini 3.8 Live Extended Thinking（High）的 $3.50，低于 GPT-Live-1（Astra，medium）的 $5.83，并且比 GPT-Realtime-2.1 High 的 $10.75 便宜约 2.2 倍 祝贺 @elonmusk 和 @SpaceXSI 团队 🚀 更多详情见下方 ⬇️

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).
