For deeper analysis and transparency into the results, this page covers the metrics for each dataset and the results per trial for all 3 benchmarks in the index. It also keeps the results of SWE-Bench-Pro Hard for reference; they do not count toward the index.
Code Index per benchmark
Here we show not only the Index score per benchmark, but also the consumed tokens and the total cost of each model.

Trial outcomes
Below you can find the outcome of each trial. Each model ran three trials per task, which resulted in either PASS, FAIL, or ERROR. Each is described below, along with the error description, task domain, and task empirical difficulty, which can be seen by hovering each result dot.
