+# Hybrid Policy Distillation: Qwen2.5-1.5B Student
+
+This repository contains a **Qwen2.5-1.5B student model** distilled from **Qwen2.5-7B-Thinking** using **Hybrid Policy Distillation (HPD)**, as presented in the paper [Hybrid Policy Distillation for LLMs](https://huggingface.co/papers/2604.20244).
+
+## Overview
+
+Knowledge distillation (KD) is a powerful paradigm for compressing large language models (LLMs). Hybrid Policy Distillation (HPD) is a framework designed to make policy distillation more stable and efficient for reasoning-oriented models. It integrates the complementary advantages of forward and reverse KL to balance mode coverage and mode-seeking, and combines off-policy data with lightweight, approximate on-policy sampling.

+## Benchmark Performance
+
+The following table shows the performance of the distilled student model compared to the teacher model across various reasoning benchmarks:
+
+| Model | AIME24 | AIME25 | AMC | MATH | OlympiadMath | GPQA |
+| --- | ---: | ---: | ---: | ---: | ---: | ---: |
+| Qwen2.5-7B-Thinking (Teacher) | 28.13 | 27.19 | 71.72 | 87.48 | 58.50 | 43.43 |
+| **Qwen2.5-1.5B-Thinking (Student)** | **7.71** | **9.89** | **39.84** | **63.40** | **32.53** | **28.09** |
