# ​**PCL-Reasoner-V1**​

## Model Overview  
We release ​PCL-Reasoner-V1​, a model trained based on ​Qwen2.5-32B-Base​ and undergoes high-performance supervised fine-tuning based on the ​MindSpore framework​ and ​Ascend hardware. After fine-tuning, the model demonstrates significant improvements in mathematical reasoning capabilities. PCL-Reasoner-V1 achieves 85.7% and 84.2% respectively on AIME 24 and AIME 25, which position PCL-Reasoner-V1 among the top-tier models in the 32B parameter class on AIME24/25.

## Evaluation
We used the ​**Avg@32 metric**​ (averaging 32 sampling attempts per query) for evaluation.
