Cursor's journey began by essentially cloning GitHub Copilot's in-editor code completion. They initially called it Copilot++ and steadily improved it, focusing on its ability to understand multiple lines of code.

By mid-2024, the feature was rebranded as Cursor Tab (a nod to its activation method by Tab button 😉) — reflecting gains in speed and accuracy. And just a month ago, they announced a new model called Fusion, which improves support for large files.

Now, competitors are scrambling to catch up.

Starting February 13th, Zed announced in beta Edit Prediction based on the open-source Zeta model.

And Windsurf announced Wave 3, in addition to supporting MCP (Model Context Protocol), also improved their autocomplete model in the editor, calling it Tab-to-jump.

And GitHub Copilot itself doesn't want to be left behind. Currently, the "Next Edit Suggestion" feature is in preview — it needs to be activated in the settings (video).
