Depending on use case and application, different models may provide better responses to users. We\u2019re committed to providing model choices that work for your business processes.<\/p>\n\n\n\n<p>Starting <strong>October 27, 2025<\/strong>, <strong>GPT-4.1<\/strong> became the default model for all newly created agents, replacing GPT-4o. Testing shows meaningful gains in both latency and response quality, helping agents deliver faster, more consistent results. GPT-4o will remain available through November 26, 2025, and agents in production will continue to leverage this model until then. However, you can update the model and opt in to GPT-4.1 today through the <a href=\"https:\/\/learn.microsoft.com\/en-us\/microsoft-copilot-studio\/authoring-select-agent-model?branch=main\" target=\"_blank\" rel=\"noreferrer noopener\">model-selection experience<\/a>.<\/p>\n\n\n<figure data-wp-context=\"{&quot;imageId&quot;:&quot;69e293eca7653&quot;}\" data-wp-interactive=\"core\/image\" class=\"wp-block-image size-full wp-lightbox-container\"><img decoding=\"async\" data-wp-class--hide=\"state.isContentHidden\" data-wp-class--show=\"state.isContentVisible\" data-wp-init=\"callbacks.setButtonStyles\" data-wp-on-async--click=\"actions.showLightbox\" data-wp-on-async--load=\"callbacks.setButtonStyles\" data-wp-on-async-window--resize=\"callbacks.setButtonStyles\" alt=\"\" src=\"https:\/\/www.microsoft.com\/en-us\/microsoft-copilot\/blog\/wp-content\/uploads\/2025\/11\/3-Model-Choice-1.webp\" alt='A screenshot of an agents model choice options, including GPT-4.1 marked as \"default\" and three GPT-5 options in preview.' class=\"wp-image-6399 webp-format\" data-orig-alt=\"\" src=\"https:\/\/www.microsoft.com\/en-us\/microsoft-copilot\/blog\/wp-content\/uploads\/2025\/11\/3-Model-Choice-1.webp\"><button\n\t\t\tclass=\"lightbox-trigger\"\n\t\t\ttype=\"button\"\n\t\t\taria-haspopup=\"dialog\"\n\t\t\taria-label=\"Enlarge\"\n\t\t\tdata-wp-init=\"callbacks.initTriggerButton\"\n\t\t\tdata-wp-on-async--click=\"actions.showLightbox\"\n\t\t\tdata-wp-style--right=\"state.imageButtonRight\"\n\t\t\tdata-wp-style--top=\"state.imageButtonTop\"\n\t\t>\n\t\t\t<svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"12\" height=\"12\" fill=\"none\" viewBox=\"0 0 12 12\">\n\t\t\t\t<path fill=\"#fff\" d=\"M2 0a2 2 0 0 0-2 2v2h1.5V2a.5.5 0 0 1 .5-.5h2V0H2Zm2 10.5H2a.5.5 0 0 1-.5-.5V8H0v2a2 2 0 0 0 2 2h2v-1.5ZM8 12v-1.5h2a.5.5 0 0 0 .5-.5V8H12v2a2 2 0 0 1-2 2H8Zm2-12a2 2 0 0 1 2 2v2h-1.5V2a.5.5 0 0 0-.5-.5H8V0h2Z\" \/>\n\t\t\t<\/svg>\n\t\t<\/button><\/figure>\n\n\n\n<div class=\"wp-block-buttons is-content-justification-center is-layout-flex wp-container-core-buttons-is-layout-a89b3969 wp-block-buttons-is-layout-flex\">\n<div class=\"wp-block-button\"><a class=\"wp-block-button__link wp-element-button\" href=\"https:\/\/learn.microsoft.com\/en-us\/microsoft-copilot-studio\/authoring-select-agent-model?branch=main\" target=\"_blank\" rel=\"noreferrer noopener\">Learn how to select a primary AI model for your agent<\/a><\/div>\n<\/div>\n\n\n\n<p>In addition, Copilot Studio is expanding availability of the <strong>GPT-5 family of models<\/strong>, first introduced in August 2025.

These models bring enhanced reasoning, richer dialogue capabilities, and more flexible problem-solving for complex scenarios. Please note that GPT-5 models remain in public preview and are not yet recommended for production use.<\/p>\n\n\n\n<p>Together, these updates give makers access to the latest OpenAI advancements while maintaining continuity for existing agents.

This allows agents to access customer-specific or system-specific content dynamically, without manual updates or re-training. For example, an agent could read the latest policy document stored in an MCP resource, summarize an uploaded file, or use current data from an API\u2014securely and in context. <\/p>\n\n\n\n<p>This enhancement builds upon the existing <a href=\"https:\/\/www.microsoft.com\/en-us\/microsoft-copilot\/blog\/copilot-studio\/model-context-protocol-mcp-is-now-generally-available-in-microsoft-copilot-studio\/\" target=\"_blank\" rel=\"noreferrer noopener\">MCP integration in Copilot Studio<\/a>, supporting deeper connections between agents and the systems they support.

The themes give you category-level insights into customer intent and frequent topics, with a more manageable number of groups. <\/p>\n\n\n\n<p>\n  In the Themes list, you can see key metrics such as question volume, response rate, and user satisfaction. This at-a-glance overview makes it easier to see which topics your agent handles well and focus on areas where it may need refinement. Makers with the appropriate permissions can also drill down into each theme to review specific user questions, agent responses, and related metrics. This deeper visibility helps identify patterns in user intent, uncover gaps in coverage, and guide targeted improvements to knowledge and content.\n<\/p>\n\n\n<figure data-wp-context=\"{&quot;imageId&quot;:&quot;69e293ecab8dc&quot;}\" data-wp-interactive=\"core\/image\" class=\"wp-block-image size-full wp-lightbox-container\"><img decoding=\"async\" data-wp-class--hide=\"state.isContentHidden\" data-wp-class--show=\"state.isContentVisible\" data-wp-init=\"callbacks.setButtonStyles\" data-wp-on-async--click=\"actions.showLightbox\" data-wp-on-async--load=\"callbacks.setButtonStyles\" data-wp-on-async-window--resize=\"callbacks.setButtonStyles\" src=\"https:\/\/www.microsoft.com\/en-us\/microsoft-copilot\/blog\/wp-content\/uploads\/2025\/11\/7-Themes.webp\" alt=\"A screenshot of the Themes section, showing five question themes, the number of questions in each theme, the percentage of answered questions, and thumbs up\/thumbs down feedback reactions from users.\" class=\"wp-image-6405 webp-format\" data-orig-src=\"https:\/\/www.microsoft.com\/en-us\/microsoft-copilot\/blog\/wp-content\/uploads\/2025\/11\/7-Themes.webp\"><button\n\t\t\tclass=\"lightbox-trigger\"\n\t\t\ttype=\"button\"\n\t\t\taria-haspopup=\"dialog\"\n\t\t\taria-label=\"Enlarge\"\n\t\t\tdata-wp-init=\"callbacks.initTriggerButton\"\n\t\t\tdata-wp-on-async--click=\"actions.showLightbox\"\n\t\t\tdata-wp-style--right=\"state.imageButtonRight\"\n\t\t\tdata-wp-style--top=\"state.imageButtonTop\"\n\t\t>\n\t\t\t<svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"12\" height=\"12\" fill=\"none\" viewBox=\"0 0 12 12\">\n\t\t\t\t<path fill=\"#fff\" d=\"M2 0a2 2 0 0 0-2 2v2h1.5V2a.5.5 0 0 1 .5-.5h2V0H2Zm2 10.5H2a.5.5 0 0 1-.5-.5V8H0v2a2 2 0 0 0 2 2h2v-1.5ZM8 12v-1.5h2a.5.5 0 0 0 .5-.5V8H12v2a2 2 0 0 1-2 2H8Zm2-12a2 2 0 0 1 2 2v2h-1.5V2a.5.5 0 0 0-.5-.5H8V0h2Z\" \/>\n\t\t\t<\/svg>\n\t\t<\/button><\/figure>\n\n\n\n<div class=\"wp-block-buttons is-content-justification-center is-layout-flex wp-container-core-buttons-is-layout-a89b3969 wp-block-buttons-is-layout-flex\">\n<div class=\"wp-block-button\"><a class=\"wp-block-button__link wp-element-button\" href=\"https:\/\/learn.microsoft.com\/en-us\/microsoft-copilot-studio\/analytics-themes\" target=\"_blank\" rel=\"noreferrer noopener\">Discover how to analyze user questions by theme<\/a><\/div>\n<\/div>\n\n\n\n<p>\n  The feature is automatically available for agents that use generative answers and have received at least 50 user questions within the past seven days.
