Corrections and updates
- The Turkish version first posted on Instagram described the $0.10-per-hour price as being for batch translation. The model does transcription, not translation; the price is for batch transcription, and the Turkish text has been corrected. The English text was accurate.
- After this story was published, Microsoft AI’s MAI-Transcribe-2-Streaming, released on October 1, took first place on the Artificial Analysis streaming leaderboard. As of October 9, Grok Voice Transcribe 2.0 ranks second, and the leaderboard has 45 entries.
