CursorCore is a series of open-source models designed to assist in programming through aligned coding instructions, supporting functionalities such as automated editing and inline chatting. These capabilities mimic core features of proprietary AI programming tools like Cursor. This project, powered by the open-source community, aims to enhance the application of AI in programming, enabling developers to write and edit code more efficiently. Currently in its early stages, the project has already demonstrated its potential for improving coding efficiency and supporting code generation.
