xAI models are now integrated into Microsoft Copilot Studio, introducing Grok 4.1 Fast for enhanced reasoning and flexible agent design. Available for U.S. makers, Grok 4.1 Fast supports deep tool use and complex workflows, ensuring businesses can optimize their agent strategies effectively. This model expands the multi‑model lineup alongside OpenAI and Anthropic, committed to responsible AI practices with thorough security and quality evaluations before rollout. Notably, customer data remains secure, as xAI’s models are hosted externally and not used for training. Currently in preview and off by default, Grok 4.1 Fast requires organization administrator opt-in for use. Existing models remain unchanged for those not opting in, allowing seamless transition and maintaining operational continuity. This addition emphasizes the importance of choosing the right model for diverse business scenarios, empowering makers to build with confidence and creativity.
