GitHub Copilot is a pioneering tool that harnesses Generative AI (GAI) to craft both boilerplate and intricate code snippets. Recently, Microsoft made the implementation of its coding assistant within Visual Studio Code open-source, inviting further enhancements from the broader developer community. Additionally, the company shed light on its comprehensive utilization of AI assistants throughout the development lifecycle. This AI assistant is integral to Microsoft's code review process, impacting more than 600,000 pull requests (PRs) each month, encompassing nearly 90% of the company's total PRs. By automatically inspecting code, appending comments, flagging issues, and proposing enhancements, this assistant dramatically shortens review cycles and elevates code quality.
