"Grok Voice Think Fast 2.0" Launches, Supporting Both Transcription and Voice Interaction

xAI unveiled Grok Voice Think Fast 2.0, a new voice AI model for speech-to-speech conversation and transcription.

The model improves response quality, reasoning, and tool-use reliability, and it beats many competitors on benchmarks.

It also raises transcription accuracy across multiple languages and is more robust in noisy environments.

Existing grok-voice-latest users will be automatically switched to the new model starting August 5, 2026.
