The median turn latency is 53.4 seconds per prompt, not per whole build, which derives to 8.0 min across the full nine prompt specification. That is a tenth percentile of 28.7 seconds and a ninetieth percentile of 82.7 seconds across 45 recorded executions.

How reliable is Cursor?

86.7% of recorded executions met the published pass criterion with no operator intervention. 3 were partial and 3 failed outright. Every one of those rows is published on this page.

Coding agents / rank 2 of 17 / cycle 04

Cursor benchmark

The strongest edit loop we measured. It keeps a large working set in view, so the tenancy constraint from prompt 3 survived every later change without being restated. As a coding agent it produces no interface of its own, which caps the design subscore: what you get is exactly the quality of the framework and components you point it at. Everything it writes lands in your repository, so ownership is total.

Seeded at launch

The reader scores, lab notes and open ratings published here were written by this lab in August 2026 to populate the reader column before the site had readers. They are not customer submissions, they are not vendor supplied and nobody was paid for them. Anything submitted since then comes from a registered account. The lab index is measured from logged runs and is unaffected either way.

What agent performance looked like in practice

Across 45 recorded executions this product met the published pass criterion cleanly 39 times, partially 3 times and failed 3 times. The rows above carry the reviewer note for every non clean outcome, which is the only way to tell a product that fails loudly from one that fails quietly.
