xAI Docs release notes – June 17, 2026

Enterprise / Build

• Added “Restricting login methods” section documenting two new policies in requirements.toml:
  • disable_api_key_auth – forces interactive IdP login and disables xai.api_key authentication.
  • force_login_team_uuid – pins login to one or more team UUIDs (automatically enables the above policy).
• Added “Locking bypass-permissions mode” section explaining the disable_bypass_permissions_mode setting under [ui].

Voice Agent (Audio)

• Updated all code samples and references to use grok-voice-latest as the recommended model.
• Deprecated grok-voice-fast-1.0; it remains available for existing integrations but new projects should use grok-voice-latest.
• Added documentation for the new reasoning_effort parameter (supported on grok-voice-latest and grok-voice-think-fast-1.0).
• Updated REST API reference to include reasoning_effort in session configuration and query parameters.

Imagine / Video generation

• Bumped default/recommended video model from grok-imagine-video to grok-imagine-video-1.5 across Python, JavaScript, and cURL examples.
