Custom engine copilots for Microsoft 365 overview

  • Article

Custom engine copilots are conversational Teams bots designed to harness the powerful capabilities of Large Language Models (LLMs) for seamless user interaction. These advanced bots mark a significant departure from traditional bots, offering an extensive range of features that elevate the overall user experience.

Custom engine copilots utilize LLM technology at their core that allows them to easily understand and respond to user queries, creating dynamic and immersive interactions. Custom engine copilots also offer advanced functionalities such as UI manipulation, task execution, and content creation, making them indispensable tools for streamlining workflows and boosting productivity.

Important

  • Custom engine copilots are conversational Teams bots with custom LLM, therefore they don't require Copilot for Microsoft 365 license to build, debug and deploy.
  • The cost of a custom engine copilot depends on the Azure services consumed in the app. To estimate the cost, visit the Azure Pricing Calculator.

Build custom engine copilots

For enterprises seeking bot solutions that are precisely customized to user demands and scenarios, using Teams AI Library to utilize LLMs that adhere to Microsoft's UX principles and are compatible with Teams and Microsoft 365 is a great choice. Developing custom engine copilots with the Teams AI Library can provide more natural, intuitive, and specialized user interaction experiences. This option is advantageous for developers wishing to customize model selection and orchestration, applying prior experience in Teams bot development, or aiming to ensure accessibility for all Microsoft 365 users.

Developers can also utilize the Teams Toolkit to easily construct their projects, taking advantage of its prebuilt templates for a seamless project launch, offering an ideal solution for quick starts, easy debugging, and deployment.
