Duties include:

• Model training and optimization: Design and implement large language model training strategies, including supervised fine-tuning (SFT), reinforcement learning (such as GRPO, PPO), etc., to enhance the model's intelligence in the Web3 field.

• Data processing and generation: Build a high-quality training dataset, perform data distillation and Long&Short Chain of Thought (Long&Short Chain of Thought, CoT) data generation to ensure that the model has strong inference abilities.

• Model architecture and evaluation: Explore and apply advanced model architectures such as expert mixing (MoE), develop model evaluation frameworks and metrics, and continuously optimize model performance.

• Distributed training and deployment: Develop and maintain distributed training schemes for models to ensure efficient training and stable deployment.

• Technological frontier exploration: Track the latest research dynamics in the AI field, such as OpenAi GPT-4.5, DeepSeek-R1, etc., and promote technological innovation and application in actual business.
