Notes

Methodology

This adapter reads the public DeepSWE v1.1 live leaderboard published by Datacurve, keeps each frontier model's best run across reasoning efforts on 113 original long-horizon software engineering tasks, ranks them by pass rate, and stores daily StoryOps snapshots so the skyline replays how the coding frontier moves.

Observed 51 DeepSWE v1.1 runs across 19 models at 2026-08-04T01:34:32.908483+00:00.
