The model is <strong>available worldwide<\/strong> for customers in <strong>early release environments<\/strong>, and Microsoft classifies it as <strong>experimental<\/strong> for now.<\/p>\n<p>The new option is <strong>off by default<\/strong>. It becomes visible to makers only after an administrator <strong>opts in at the tenant level<\/strong> and <strong>enables external model providers<\/strong> for the selected environments. <strong>Existing agents and workflows stay unchanged<\/strong> unless an admin turns the option on.<\/p>\n<p>&nbsp;<\/p>\n<h2>What is Microsoft Copilot Studio?<\/h2>\n<p><strong>Microsoft Copilot Studio<\/strong> is Microsoft\u2019s <strong>low-code environment<\/strong> for building, orchestrating, and governing <strong>AI agents<\/strong>. It sits on top of <strong>Microsoft Power Platform<\/strong> and connects to enterprise data and systems. Through a <strong>multi-model selector<\/strong>, teams can pick different models for different agents while keeping <strong>orchestration, governance, and lifecycle management in one place<\/strong>.<\/p>\n<p>&nbsp;<\/p>\n<h2>Customer benefits at a glance<\/h2>\n<ul>\n<li><strong>Better answers per use case<\/strong>, because teams match the <strong>model to the task<\/strong>.<\/li>\n<li><strong>Easier compliance conversations<\/strong> with <strong>EU stakeholders<\/strong> on where data is handled.<\/li>\n<li><strong>Lower switching cost<\/strong> when trying a <strong>new model<\/strong>.<\/li>\n<li><strong>Consistent oversight<\/strong>, since nothing leaves your <strong>admin perimeter<\/strong>.<\/li>\n<li><strong>Confident experimentation<\/strong> ahead of <strong>production use<\/strong>.<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<h2>Key capabilities<\/h2>\n<ul>\n<li>Built for <strong>long-horizon tasks<\/strong> and <strong>reliable multi-tool calling<\/strong>.<\/li>\n<li>Produces <strong>structured output<\/strong> for downstream code.<\/li>\n<li><strong>Reasoning effort is configurable per request<\/strong>, from quick replies to complex agent runs.<\/li>\n<li>Selectable directly in the <strong>Copilot Studio model picker<\/strong> once enabled.<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<h2>Why governed model choice matters now<\/h2>\n<p>More organizations are <strong>moving agents from pilots into production<\/strong>. A single default model rarely fits <strong>every language, region, or workload<\/strong>. Governed model choice <strong>reduces risk<\/strong>, because third-party models stay inside known admin controls. It <strong>increases clarity<\/strong> for EU teams that must show where data is processed. And it <strong>saves time<\/strong>, because evaluation happens without separate vendor onboarding.<\/p>\n<p>&nbsp;<\/p>\n<h2>What organizations should do now<\/h2>\n<ul>\n<li><strong>Review<\/strong> which agents could benefit from an alternative model, and list them.<\/li>\n<li><strong>Validate<\/strong> the <strong>data-processing terms<\/strong> for external models against your compliance policy.<\/li>\n<li><strong>Enable<\/strong> the <strong>two required switches<\/strong> for a <strong>single test environment first<\/strong>.<\/li>\n<li><strong>Monitor<\/strong> experimental-model usage and keep it <strong>out of production<\/strong> until testing completes.<\/li>\n<li><strong>Update<\/strong> internal governance guidance so makers know <strong>when external models are allowed<\/strong>.<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<h2>Ready to review your Copilot Studio licensing?<\/h2>\n<p>SCHNEIDER IT MANAGEMENT helps you <strong>assess the licensing and governance impact<\/strong> of new model options in <strong>Copilot Studio<\/strong>.
