SpaceX AI推出新一代语音模型Grok Voice Think Fast 2.0，在多项基准测试中取得领先成绩1。该模型在Tau Voice基准测试中以56.5%的得分排名第一，击败OpenAI、Google等竞争对手1。在Artificial Analysis的Speech to Speech Index测试中，高推理能力版本得分达82.9%，仅次于千问Qwen Audio 3.0 Realtime Plus的84.1%1。
Think Fast 2.0在响应速度和成本效率上均实现显著提升1。平均首音频响应时间仅为0.70秒，是榜单前五名中唯一低于1秒的模型，相比前代的1.25秒大幅改进1。定价方面，该模型每分钟收费0.08美元（约每小时4.80美元），仅为GPT-Realtime-2.1 High版本的45%1。在转写准确率上，Think Fast 2.0相比前代提升约1.4倍，相比Deepgram Nova 3和ElevenLabs Scribe v2的提升幅度为1.5至2倍1。此外，该模型的中位数推理Token消耗仅为前代的约40%，综合得分相比上一代的75.7%提升至82.9%，增幅达7.2个百分点1。
Elon Musk's SpaceX AI has unveiled Grok Voice Think Fast 2.0, a next-generation speech-to-speech model that has achieved top rankings in industry benchmarks 1. The model scored 56.5% on the Tau Voice benchmark test, securing the first-place position ahead of competitors including OpenAI and Google 1. Additionally, in the Artificial Analysis Speech to Speech Index, the high-reasoning version of the model achieved a score of 82.9%, placing it just behind Qwen Audio 3.0 Realtime Plus at 84.1% 1.
The model delivers significant performance improvements in both speed and accuracy 1. With an average first audio response time of just 0.70 seconds, Grok Voice Think Fast 2.0 is the only model in the top five rankings to remain below the one-second threshold—a substantial improvement from the previous generation's 1.25 seconds 1. The transcription accuracy has increased by approximately 1.4 times compared to Think Fast 1.0, and by 1.5 to 2 times compared to competitors Deepgram Nova 3 and ElevenLabs Scribe v2 1. The model also demonstrates more efficient token consumption, with median reasoning token usage dropping to roughly 40% of the previous generation 1.
Pricing represents a competitive advantage for developers 1. At $0.08 per minute for audio input—equivalent to $4.80 per hour—Grok Voice Think Fast 2.0 costs approximately 45% of OpenAI's GPT-Realtime-2.1 High offering 1. The comprehensive performance score of 82.9% marks a 7.2 percentage point improvement over the previous model's 75.7% 1.
