Microsoft Adds xAI’s Grok 4.1 Fast to Copilot Studio, Expands AI Model Choices
•Microsoft Copilot Studio now includes xAI’s Grok 4.1 Fast in preview, offering a fast-reasoning, text-generation system for large contexts and complex workflows.
•Grok 4.1 Fast is currently limited to US-based makers in early access environments and must be explicitly enabled by administrators.
•This addition reflects Microsoft's multi-model strategy, providing organizations with more AI engine choices alongside OpenAI and Anthropic models.
•Customer data used with Grok 4.1 Fast in Copilot Studio is not retained or used for training xAI’s models, but models are hosted outside Microsoft environments.
•Microsoft emphasizes orchestration, giving enterprises access to multiple AI engines while maintaining administrative control and undergoing security evaluations.
