Copilot Studio and Azure AI Foundry work together. Developers can start building their AI apps in Copilot Studio, a SaaS environment that allows them to prototype, develop, and deploy quickly, allowing them to realize business value. When developers are ready to customize and monitor their AI apps and APIs, they can migrate to Azure AI Foundry, a platform as a service (PaaS), or access Azure AI capabilities from their favorite developer workspaces like GitHub and Visual Studio to create custom functions, use source control, and integrate existing code from various languages.
