|
| **Modifications by Open-Jev:** `package/checkpoint/adapter/` contains trained |
| LoRA weights for the Qwen text backbone. `package/checkpoint/head.pt` is a |
| trained scalar decision head whose lineage starts from the upstream |
| Yes-minus-No output-embedding readout. `model.json` selects the pinned base |
| and the Open-Jev decision interface; `temperature.json` stores calibration |
| fitted on a separate split. These files are modified training products and |
| are not unmodified Qwen weights. Their training-stage and initialization |
| provenance is recorded in `package/provenance.json`. |
|
|
| The inference weight package is Apache-2.0. Original Open-Jev source code is |
| MIT; its separate license is included as `LICENSE-CODE`. Base weights, |
| tokenizer files, third-party runtime libraries and training dataset rows |
| are not bundled here. |

| The pinned Qwen model card requests citation of: Qwen Team, |
| *Qwen3.8-Max: A New Bar for Coding and Cowork*, August 2026, |
| <https://qwen.ai/blog?id=qwen3.8>. This citation title comes from that model |
| card and does not identify this 27B checkpoint as the hosted Qwen3.8-Max model. |
