xAI Docs release notes

Developers / REST API — Video inference

Updated the Videos API reference to document reference_audios:

• Optional array of reference audio clips (voice identity) for reference-to-video generation
• Supported on select video models; at most 3 clips
• May be used without reference_images (audio-only reference-to-video); any reference image or audio selects reference-to-video mode
• Each clip requires a url: base64 audio data URL or an HTTP(S) URL to a downloadable clip
