Introduction of E1-Math-1.5B

Model Details of E1-Math-1.5B

Introduction

E1-Math-1.5B is a language model fine-tuned from DeepSeek-R1-Distilled-Qwen-1.5B. It is trained for Elastic Reasoning by budget-constrained rollout strategy, integrated into GRPO, which teaches the model to reason adaptively when the thinking process is cut short and generalizes effectively to unseen budget constraints without additional training.
