The third era of AI software development

A third era of AI software development is emerging as autonomous cloud agents take on larger tasks over longer timescales.

Meet the new Cursor

Cursor 3 is a unified workspace for building software with agents.

Introducing Composer 2

Frontier-level coding with strong CursorBench results, higher token efficiency, and a faster default variant.

How we compare model quality in Cursor

We use a hybrid online-offline eval process to keep our understanding of model quality aligned with what developers actually do.

Continually improving our agent harness
