Qwen3 0.6B NFL play normalizer, QLoRA adapter
This repository contains a LoRA adapter, not a merged standalone model. Load it onto Qwen/Qwen3-0.6B at revision c1899de289a04d12100db370d81485cdf75e47ca.
Training
The adapter trained for one epoch on a deterministic 25,000-record subset of the approved real 2019-2022 nflverse corpus. It used 4-bit NF4 QLoRA on a Tesla T4, seed 20260819, batch size 1, gradient accumulation 8, and learning rate 2e-4.
Frozen 2023 discovery comparison
Both rows used the same 30 frozen 2023 descriptions, system instruction, deterministic generation, and strict no-repair scorer.
| Model | Exact records | Valid JSON | Valid schema |
|---|---|---|---|
| Untuned Qwen3 0.6B | 0 / 30 | 0 / 30 | 0 / 30 |
| This QLoRA adapter | 27 / 30 | 30 / 30 | 30 / 30 |
The adapter reached 27/30 exact records, below the project's 95% promotion bar. It was not evaluated on the frozen 2024 confirmation set or untouched 2025 final set. Do not claim production readiness or final generalization from this discovery result.
