GitHub and OpenAI has announced Copilot, an AI pair programmer that helps developers to write code faster and with less work by suggesting autocompletion based on context drawn from comments and code. Suggestions can be as simple as individual lines through to whole functions. GitHub Copilot is powered by OpenAI Codex, a new AI system created by OpenAI that was trained on publicly available source code and natural language. Copilot is currently available as a closed beta technical preview in a Visual Studio Code extension. You can read more about it on the new Copilot website.
