- Automatically detects dozens of languages and handles mid-recording language switches in a single pass.
- Reduced word error rate from 20.6% to 6.8% on short multilingual voice command evaluations.
- Includes diarization, timestamps, and key terms in the base pricing.
- Becomes the default model in the Speech-to-Text API, with Grok Voice Transcribe 1.0 scheduled for deprecation in coming weeks.
