GitHub Copilot: your AI pair programmer (2021)

GitHub launched a technical preview of GitHub Copilot, an AI pair programmer powered by OpenAI Codex that suggests code in real time. The tool, developed with OpenAI, aims to help developers write code faster by generating whole lines or functions based on context.

Introducing GitHub Copilot: your AI pair programmer Today, we’re launching a technical preview of GitHub Copilot, a new AI pair programmer that helps you write better code. Today, we are launching a technical preview of GitHub Copilot http://copilot.github.com , a new AI pair programmer that helps you write better code. GitHub Copilot draws context from the code you’re working on, suggesting whole lines or entire functions. It helps you quickly discover alternative ways to solve problems, write tests, and explore new APIs without having to tediously tailor a search for answers on the internet. As you type, it adapts to the way you write code—to help you complete your work faster. Developed in collaboration with OpenAI, GitHub Copilot is powered by OpenAI Codex, a new AI system created by OpenAI. OpenAI Codex has broad knowledge of how people use code and is significantly more capable than GPT-3 in code generation, in part, because it was trained on a data set that includes a much larger concentration of public source code. GitHub Copilot works with a broad set of frameworks and languages, but this technical preview works especially well for Python, JavaScript, TypeScript, Ruby and Go.
