# Model Summary
|
||||||
|
|
||||||
|
This model enhances the reasoning capabilities of the small 1.5B parameter `DeepSeek-R1-Distill-Qwen-1.5B` LLM using reinforcement learning (RL). Trained efficiently on 4 A40 GPUs in under 24 hours, it achieves significant gains in mathematical reasoning benchmarks (e.g., 80% accuracy on AMC23, 46.7% on AIME24, surpassing `o1-preview`). This cost-effective approach demonstrates the potential of RL for boosting reasoning in resource-constrained settings.
|
||||||
|
|
||||||
|
|
||||||
|
## Evaluation
|
||||||
|
### Performance Highlights
|
||||||
|
- **Open-RS1**: 53.0% avg. score
|
||||||
|
- **Open-RS2**: 55.7% avg. score, 80.0% on AMC23
|
||||||
|
- **Open-RS3**: 56.3% avg. score, 46.7% on AIME24 (outperforms `o1-preview` at 44.6%)
|
||||||
|
- Competitive MATH-500 scores; Minerva lags behind 7B models.
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
### Cost Efficiency
|
||||||
|
Our approach uses 7,000 samples (42,000 total outputs) and costs ~$42 on 4x A40 GPUs in 24 hours, compared to thousands of dollars for baseline models.
