GitHub Copilot works alongside you directly in your editor, suggesting whole lines or entire functions for you. GitHub Next has been working to move past the editor and evolve GitHub Copilot into a readily accessible AI assistant throughout the entire development lifecycle. This is GitHub Copilot X—our vision for the future of AI-powered software development. They are not only adopting OpenAI’s new GPT-4 model, but are introducing chat and voice for Copilot, and bringing Copilot to pull requests, the command line, and docs to answer questions on your projects.

Even though the GPT-4 was just released, they already notice significant gains in logical reasoning and code generation. With GPT-4, the state of AI is beginning to catch up with GitHub's ambition to create an AI pair programmer that assists with every development task at every point in the developer experience.
