Microsoft is helping developers build their own ChatGPT-compatible AI copilots

Microsoft has a lot of news at this year's Build conference around its AI "copilots" for Windows 11 and other products, but it wants third-party developers in on the action too. The company announced that it has expanded its AI plugin ecosystem and provided a framework for building AI apps and copilots. At the same time, it's adopting the same open plugin standard that OpenAI uses for ChatGPT to ensure it'll work alongside its Windows 11, 365 and other copilots. Microsoft introduced the idea of copilots nearly two years ago. Those are applications that use AI and LLMs (large language models) to help users with complex cognitive tasks like writing sales pitches, generating images and more.
