# JADE

JADE (Just Another Decision Engine) by Sreeraj Ramachandran: a rank-8 LoRA and a 255-way decision head on Qwen3.8-27B. Each question returns exactly one answer code, turned into a temperature-scaled probability per option; choice and yes/no only, no generated text.

The repo holds only the LoRA (plus a vLLM-format adapter) and the decision head, so the Qwen3.8-27B base is needed. Temperature fitted on a calibration split. Text only, no score questions, 8,192 tokens. Trained on JADE-Data, 160,017 synthetic examples under Apache-2.0. The card says it is not Jev and not affiliated with TypeSafe AI; the prompt renderer is adapted from AutoJev (MIT). The maker's own run of the third-party Decision Index 0.2.1 kit gives 53.16; its in-distribution dev accuracy is not a fair test.

## What it decides

- **choice** — picks one option from a set
- **noul** — answers a yes/no question with one probability
- **route** — sends the input to one of several destinations
