Main features of DistilQwen2

  • Enhanced instruction following: Based on knowledge distillation technology, DistilQwen2 executes various instructions more accurately and improves the model's instruction-following ability.
  • Lightweight deployment: The model has fewer parameters and is suitable for deployment in resource-constrained environments, such as mobile devices and edge computing devices.
  • Efficient computation: The model scale is small, computational efficiency is higher, and it can quickly respond to user instructions.
  • Multilingual support: Supports multiple languages, especially with good processing capability in Chinese and English.

Technical principles of DistilQwen2

  • Knowledge distillation: Transfers the knowledge of a large model to a smaller model through the training process, achieving similar performance with smaller computational resources.
  • Task-aware curriculum planning: Analyzes the difficulty and characteristics of different tasks, optimizes instruction data, and improves the efficiency of distillation training.
  • Instruction data optimization: The teacher model generates or expands instruction data, increasing data diversity, including task types, lengths, and languages.
  • Model distillation training: Conducts distillation training based on two methods, supervised fine-tuning (SFT) and direct preference optimization (DPO), to improve the performance of the student model.
  • Multi-turn dialogue data construction: Requires the teacher model to ask follow-up questions based on the answer information from the previous turn, improving the model's performance in multi-turn dialogues.
  • Model self-distillation: The student model rewrites the teacher model's answers, reducing distribution differences between models and reducing the problem of catastrophic forgetting.
  • Quality verification: Performs quality verification on the optimized instruction data to ensure the accuracy of the distillation data source.
