Mobile-ReasoningLLM-v0-1.5B is a fine-tuned derivative of Qwen2.5-1.5B, optimized for reasoning tasks in mathematics generation. It supports up to 48K output tokens for math problems. This model is designed for both commercial and non-commercial research use. This repository contains the evluation code of Mobile-ReasoningLLM-v0.1(Mobile-Flash-ReasoningLLM-v0-1.5B) which starts to explore experience learning besides of sparse reward learning in the reinforcement learning after R1-Like reinforcement learning and it's variants including curriculumn learning. In this work, I start to explore the rl training algorithm after pre-training, r1-reinforcement learning, r1-curriculumn reinforcement learning to reduce the difficulty of sparse reward in the RL-Post training stage. It takes about 4 days to update Mobile-ReasoningLLM-v0 to Mobile-Flash-ReasoningLLM-v0-1.5B on 8 NVIDIA A800 80G GPUs.

Inference Example

python

import transformers
import torch
model_id = "deepgo/Mobile-ReasoningLLM-v0.1-1.5B"
pipeline = transformers.pipeline(
    "text-generation",
    model=model_id,
    model_kwargs={"torch_dtype": torch.bfloat16},
