A Brief History of Cursor's Tab-Completion


Seamlessly create, customize, and deploy AI agents with Coplay. Cutting-edge intelligence frameworks, optimized performance, and an intuitive developer experience—all within your Unity environment.

Originating from Jacob Jackson's early code-completion tool TabNine, Babble revolutionized the space by using edit sequences for training—far superior to traditional Fill-in-the-Middle methods. Cursor's acquisition of Babble not only elevated their own offering but secured a significant data advantage, positioning them at the forefront of AI-powered coding assistants. Since Cursor owns the entire editor, they are privy to the changes initiated, accepted, and rejected by developers in a project, putting them in pole position for training the best tab-completion model.
