ARC-Challenge Enhancement Results — Proprioceptive AI
Summary
+11.8% absolute improvement on ARC-Challenge using inference-time enhancement.
No fine-tuning. No additional training of the base model.
| Metric | Value |
|---|---|
| Model | Qwen2.5-32B-Instruct (4-bit NF4) |
| Hardware | Single NVIDIA RTX 3090 (24GB) |
| Baseline | 82.2% (963/1172) |
| Enhanced | 93.9% (1101/1172) |
| Improvement | +11.8% |
Method
PerformanceEnhancer v2 is a proprietary inference-time enhancement system developed by Proprioceptive AI. It improves model accuracy without modifying the base model's weights.
Key Properties
- No fine-tuning: The base model's weights are never modified
- No test leakage: All hyperparameters selected via cross-validation on the train split only
- Lightweight: Negligible inference overhead
- Single GPU: Runs on a single RTX 3090
Evaluation Methodology
We follow a rigorous evaluation protocol:
- Train on ARC-Challenge train split only (1,119 questions)
- Select all hyperparameters via 5-fold cross-validation on training data
- Freeze all settings and run a single evaluation on the test split (1,172 questions)
- Report that single number — no cherry-picking
Additional Benchmarks
| Benchmark | Baseline | Enhanced | Delta |
|---|---|---|---|
| ARC-Challenge | 82.2% | 93.9% | +11.8% |
| TruthfulQA MC1 | 79.4% | 100.0% | +20.6% |
| HellaSwag | 91.5% | 94.0% | +2.5% |
