1. AI SDK xAI Provider Adds Grok Imagine Video 1.5 Support

Vercel. The AI SDK’s xAI provider added support for xAI’s Grok Imagine Video 1.5 model, which generates 1080p video and supports reference-to-video audio through a referenceVoiceIds option. The capability shipped in the @ai-sdk/xai@3.0.121 release, letting developers call the new video model through the same AI SDK interface used for xAI’s other models. Source

2. xAI Speech Generation Gains Timestamps and Pronunciation Controls

Vercel. A follow-up @ai-sdk/xai@4.0.40 release added speech timestamp output and pronunciation replacement options to the AI SDK’s xAI text-to-speech support, along with a providerMetadata.xai.traceId value returned from response headers for tracing requests. The release also improved error parsing for the provider’s text-to-speech endpoints so failures surface more clearly. Source
