That\u2019s why in the past 60 days, we\u2019ve enabled major models like GPT-5, GPT-5.1, Claude Sonnet 4.5 and Claude Opus 4.5 in Copilot Studio on the same day as their public release. And with new Copilot Studio platform capabilities like <a href=\"https:\/\/www.microsoft.com\/microsoft-copilot\/blog\/copilot-studio\/build-smarter-test-smarter-agent-evaluation-in-microsoft-copilot-studio\/\">agent evaluations<\/a>, we&#8217;re making it even easier to test your agent with multiple models to find the right fit. <\/p>\n\n\n\n<p>Hear directly from the team on how we are enabling model choice across Copilot Studio and Microsoft 365 Copilot:<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"Model Choice in Microsoft Copilot Studio\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube-nocookie.com\/embed\/xPFg_-1sxvI?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<p>Claude Opus 4.5 will replace Claude Opus 4.1 in Copilot Studio as an experimental model. As with any experimental model, we encourage testing it in non-production scenarios. To use Anthropic models in Copilot Studio, admins must opt in via the Microsoft 365 Admin Center. You can learn more about doing so <a href=\"https:\/\/learn.microsoft.com\/en-us\/copilot\/microsoft-365\/connect-to-ai-models\">here<\/a>.
