About GitHub Copilot

GitHub Copilot is an AI pair programmer that assists developers by suggesting whole lines or entire functions in real-time. It draws context from the code you're working on, adapts to your coding style, and helps you discover alternative solutions, write tests, and explore new APIs without manual searches. Powered by OpenAI Codex, a new AI system trained on a large dataset of public source code, GitHub Copilot is significantly more capable than GPT-3 in code generation. During its initial technical preview (announced June 2021), it works especially well for Python, JavaScript, TypeScript, Ruby, and Go. The tool aims to boost productivity by reducing boilerplate and accelerating problem-solving, though the preview had limited spots.
