xAI launches Grok Voice Transcribe 2.0, doubling accuracy at the same price

xAI 发布 Grok Voice Transcribe 2.0 语音转写模型，准确率较 1.0 翻倍

xAI released Grok Voice Transcribe 2.0 on Sep 18, claiming it's one of the most accurate speech-to-text models in real-world evals and twice as accurate as v1.0. Pricing stays at $0.10/hr for batch and $0.20/hr for streaming, with diarization, timestamps, and key terms included. It handles hard cases like noisy phone calls and short multilingual commands—word error rate on short phrases dropped from 20.6% to 6.8%. Atlassian Loom already swapped it in and pipes transcripts into Cursor for code updates. The post doesn't disclose parameter count or training details.
