I Built an Open Jev in One Week. On Its Own Benchmark, It's Ahead.
The first week of building Decisio, and how it compared with Jev on JevBench and the Decision Index. First published on Medium on 7 October 2026.
The title and some figures are out of date. On JevBench v1.6.1 Decisio is level with Jev, with the intervals overlapping. The Decision Index figures in the article come from our own 0.2.1 self-run. The 31B now has a row on the index itself: 58.09 on the public set and 58.55 on Decision Index 0.3. The benchmarks page has the current numbers.
