Grok models begin rolling out to Microsoft Copilot users

Microsoft is rolling out preview access to Grok models in Copilot for eligible Frontier Program customers using Word, Excel, and PowerPoint.

Organizations must first enable a dedicated administrative setting, which is disabled by default, and SpaceXAI has been added to Microsoft's Online Services Subprocessor List.

The preview is unavailable to Frontier customers in the EU, EFTA, and the UK, while Microsoft evaluates feedback and usage before expanding access.
