GitHub is updating its AI pair programmer, Copilot, by integrating OpenAI’s GPT-4 model and adding chat and voice support. The update, called “Copilot X,” includes a ChatGPT-like experience that allows the chatbot to recognize and explain code, recommend changes, and fix bugs. GitHub CEO Thomas Dohmke says this update will fundamentally influence the developer experience by making AI a part of every step of the developer lifecycle. The new chat feature goes beyond basic auto-complete comments and coding and functions as a true coding assistant.
