   - Training Strategy: Uses a mix-mode GRPO algorithm for reinforcement learning, where reward signals evaluate both the correctness of results and the consistency of the process and results, ensuring synchronized optimization of reasoning processes and final outcomes.
 - **Step II.2: Iterative Alignment**
   - Objective: Address common issues like repetitive crashes and poor logic in model-generated content, and enable spontaneous reasoning mode selection to enhance final performance and stability.
-  - Data Composition: Constructs preference data through Rejection Fine-Tuning (RFT), combining rule-based scoring (judging repetition, instruction following, etc.) and model scoring (cognitive scores provided by large models) to rank various model responses, building a high-quality preference dataset.

   - Training Strategy: Multi-round iterative optimization with the constructed "good/bad" preference data pairs through the MPO algorithm. This aims to correct model generation flaws and ultimately enable it to intelligently and adaptively choose whether to activate deep reasoning modes based on problem complexity.
