GitHub has implemented a new AI model in Copilot that is faster and more accurate than the previous one, as well as enhanced AI to detect vulnerabilities and block insecure coding patterns in real-time. In addition, Copilot now better understands context using a technique called Fill-In-the-Middle, which has increased the acceptance rate of code suggestions. The improvements in Copilot have resulted in a net increase of acceptance rate and reduced the frequency of unwanted suggestions. Additionally, GitHub has started applying AI to prevent vulnerabilities in code generated by Copilot, with the goal of changing the way developers avoid introducing vulnerabilities in code.
