| # JevBench |
|
|
| Cases and predictions for *JevBench: An Open Evaluation Framework for Typed |
| Decision Models*. The evaluation code is on GitHub: https://github.com/Leanmcp/jevbench JevBench evaluates models that return typed decisions |
| (a yes/no probability, a distribution over a set of choices, or an expected |
| level on an ordered rubric) on identical inputs built from public datasets. |
|
|
| ## Contents |
|
|
| | Path | What it holds | |
| |---|---| |
| | `cases/` | One JSONL file per slice. Each row is the exact request sent to every model, plus the gold answer, source revision and licence. | |
| | `images/` | Images for the ScienceQA and VQA-RAD image slices. | |
| | `predictions/<system>/predictions.jsonl` | One decision per case with the full probability vector, latency and token counts. No source text. | |
| | `analysis/` | Paired bootstrap results and the djev image ablation. | |
| | `provenance/djev/` | Serving provenance for djev-0.1 (vLLM command line, container logs, configuration). | |
| | `sources.json` | Every source dataset pinned to a Hugging Face revision, with the fields sent and withheld. | |
|
|
| Systems: `jev-1.13.0` (hosted commercial model), `djev-0.1` (open, DiffusionGemma |
| 26B-A4B backbone; `djev-0.1-images` holds its image slices), `laya-421m-en` |
| (open, ModernBERT-large encoder). Total: 24,799 decisions. |
|
|
| ## Licences |
|
|
| Each case row carries the licence of its source dataset in its `license` field; |
| licences do not merge across sources. SST-5 states no licence on its card, so |
| its cases are released without their sentence text: `state_hash` identifies each |
| sentence, which can be recovered from the pinned source revision in |
| `sources.json`. |
|
|
| ## Code |
|
|
| The harness that downloads the sources, builds and verifies these cases, runs |
| models and scores them is released under the MIT Licence at https://github.com/Leanmcp/jevbench. Each |
| `predictions/<system>/scores.json` holds the scores reported in the paper. |
