Introduction Reinforcement learning has pioneered a new Scaling paradigm in the post-training phase of large language models, a breakthrough that is increasingly attracting attention from the industry. With the successive release of OpenAI's O-series models and DeepSeek R1, the excellent performance demonstrated by the models fully proves the crucial role of reinforcement learning in the optimization process. In mid-February this year, the Hunyuan team launched the Hunyuan T1-Preview (Hunyuan-Th...
