Grok Transcribe 2.0 keeps voice AI at $0.10 an hour

SpaceXAI released Grok Voice Transcribe 2.0, claiming 2x accuracy over version 1.0 while keeping batch transcription at $0.10 per audio hour and streaming at $0.20, according to the launch announcement. The new model ranks first among 32 streaming models on Artificial Analysis, but 1.0 remains the default until 2.0 becomes default in coming weeks, so teams can A/B the opt-in model before migration. Builders shipping voice workflows should benchmark their own noisy audio rather than treat a vendor leaderboard as a guarantee, alongside the archive’s warning about transcription price expiry.
