Grok Voice 3.0 released and version 2.0 deprecated
Detected October 14, 2026, 17:07 UTC · SpaceXAI release notes
Grok Voice 3.0 has replaced version 2.0 as the target for the floating voice alias at identical pricing, while version 2.0 is now deprecated. Prior changelog entries were also retroactively adjusted to remove the "Think Fast" branding from earlier audio releases.
The documentation page tracks version history and development updates for audio-capable models. In this revision, the provider launched Grok Voice 3.0 within its interactive speech API and simultaneously marked Grok Voice 2.0 as deprecated. Older log entries were also modified to remove the "Think Fast" qualifier from versions 1.0 and 2.0 model identifiers. For billing purposes, the third-generation audio model carries the exact same usage cost as the second generation, keeping expense levels stable.
In practice, applications relying on the default rolling alias will immediately transition to the 3.0 model without requiring changes to underlying API calls or code parameters. Conversely, developers who pinned their implementations directly to the explicit 2.0 identifier will need to manually edit their model parameters to select either the new generation or the rolling alias to remain supported.
Several operational details remain unstated on the log page. While the text indicates matching pricing, it omits the absolute numeric rates per minute or token for speech sessions. Furthermore, the release notes provide no formal retirement calendar or hard shutdown date for Grok Voice 2.0, leaving it uncertain how long the deprecated endpoint will continue serving live traffic before being decommissioned.
We compare this page once a day and record every difference. The text above is written by Grok Tracker from that comparison; none of it is copied from the source.
