Cursor adds Z.ai's GLM 5.3 and a faster Flash version
Your move: GLM 5.3 Max leads Cursor's open-weight benchmark
On October 1, 2026, Cursor said GLM 5.3 and GLM 5.3 Flash are available in the editor. Cursor's model docs describe GLM 5.3 as Z.ai's open-weight coding model after GLM 5.2, with a context window of 1 million tokens and Low, High, and Max reasoning settings. Cursor says GLM 5.3 Max is the best-scoring open-weight model on CursorBench 4.0, and GLM 5.3 is billed at the same per-token rates as GLM 5.2.
Why it matters
If you use Cursor, both models can be added from Settings, then Models. GLM 5.3 draws from the Other Models allowance, so check that pool before you rely on it for a long task.
