Base and inference models
The adapter is a modification produced by QLoRA fine-tuning. It does not include
the Gemma base-model weights. See NOTICE for attribution and modification details.
Training and evaluation
- Method: Unsloth 4-bit QLoRA, rank 8, alpha 16
- Final run: 160 steps
- Training examples: 884 synthetic conversations
- Human-authored OOD set: 30 held-out examples, not used for training
- OOD JSON validity: 96.7%
- OOD schema validity: 93.3%
- Safe-filter evaluation: 8/8
The training data is synthetic and does not contain real employee personal data or
real-company confidential policies.
Intended use and limitations
This adapter is intended for an educational, local HR-assistant prototype. Backend
code, not this model, enforces document permissions and safety boundaries. The model
must not be used as the sole control for authorization, compliance, legal, labor, or
personnel decisions.
Held-out evaluation still contains premature ready decisions, missed rejections,
and one response outside the required JSON envelope. Human review and deterministic
backend validation remain required.
