Mobile-ReasoningLLM-v0-1.5B

Model Description

Mobile-ReasoningLLM-v0-1.5B is a fine-tuned derivative of Qwen2.5-1.5B, optimized for reasoning tasks in mathematics and code generation. It supports up to 64K output tokens for math problems and 65K tokens for code generation. This model is designed for both commercial and non-commercial research use. This repository contains the evluation code of Mobile-ReasoningLLM-v0 which start to update the reference model in the reinforcement learning after R1-Like reinforcement learning and it's variants including curriculumn learning. In this work, we comprehensively consider to start to free the weights of refrence model in the contiue learning of Reasoning LLMs which are already learned after R1-Like reinforcement learning and its variants. In our version zero, we further demonstrate that our design of reforcement learning enhance the reasoning ability of small language models, with SoTA results for 5 reasoning benchmarks Mobile-Reasoning-LLM-1.5B. It takes the 30 days to train Mobile-ReasoningLLM-v0 on 1T Tokens using 8 NVIDIA A800 80G GPUs following pre-training, r1-reinforcement learning, r1-curriculumn reinforcement learning, and updaets reference model in the continue r1-reinforcement learning.
