Model Overview

zhaohq/PureRL-1.5B-v11A-lam002 is a 1.5 billion parameter language model, fine-tuned by zhaohq from the Qwen/Qwen2.5-Math-1.5B base model. It is designed to excel in mathematical reasoning tasks, building on the strong foundation of its parent model. The model supports a substantial context length of 32768 tokens, allowing for processing longer and more complex inputs.

Key Training Details

This model was trained using the TRL (Transformer Reinforcement Learning) framework. A significant aspect of its training methodology is the application of GRPO (Generalized Reinforcement Learning with Policy Optimization), a method detailed in the research paper "DeepSeekMath: Pushing the Limits of Mathematical Reasoning in Open Language Models" (arXiv:2402.03300). This indicates a focus on enhancing its reasoning capabilities through advanced reinforcement learning techniques.
