Coding agents / rank 10 of 17 / cycle 04
Jules benchmark
An asynchronous agent: you hand it a task against a repository and come back to a proposed change. Judged on wall clock that is expensive, and it posts one of the slower medians in the index, but the comparison is not quite like for like since nobody sits and watches it. Change quality was good and the tests it added were real tests rather than assertions that always pass.
Composite index
68.04
of 100 | withheld vs. cycle 03
Delta not shown for cycle 04: the roster was re-based from one merged ranking into two class boards, so cycle 03 and cycle 04 ranks are not on the same scale. Resumes cycle 05.

Per axis subscores
Composite recomputed from these 9 rows: 68.04. That is the arithmetic behind the index, and you can repeat it by hand. Rounding rule: half up at two decimals, applied uniformly to all 37 published products. Code ownership has no row here: it is not scored on this board.

Turn latency distribution
Every recorded prompt duration for Jules, in seconds. Median wall clock time for one prompt, not for a whole build. The cyan tick on the whisker is the median.
Spread against the cohort
p10 84.4 s / median 146.5 s / p90 292.7 s
Scale is shared with every product in the cohort, so the bars are directly comparable between pages. Ratio of p90 to median is 2.00x.

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.

The reader index is a weighted mean of reader submitted axis scores using the published index weights, renormalised over the axes readers have scored. It is never blended into the lab index. How this works.

What agent performance looked like in practice
An asynchronous agent: you hand it a task against a repository and come back to a proposed change. Judged on wall clock that is expensive, and it posts one of the slower medians in the index, but the comparison is not quite like for like since nobody sits and watches it. Change quality was good and the tests it added were real tests rather than assertions that always pass.
Across 45 recorded executions this product met the published pass criterion cleanly 34 times, partially 7 times and failed 4 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.
