This project provides an end-to-end framework for adapting large language models to follow user instructions through supervised fine-tuning. It functions as a comprehensive training pipeline that enables the creation of specialized assistant models by minimizing the difference between predicted outputs and target responses within structured instruction datasets.
The framework distinguishes itself by integrating synthetic data generation with memory-efficient training techniques. It utilizes powerful language models to iteratively expand small sets of human-written seeds into diverse, high-quality instruction-response pairs, significantly reducing the cost of data acquisition. Furthermore, it employs parameter-efficient adaptation methods, such as low-rank matrix decomposition, to update model weights with minimal computational overhead.
The toolkit also includes utilities for model weight reconstruction, allowing users to apply calculated parameter offsets to base model checkpoints. This approach enables the distribution and deployment of fully functional fine-tuned models without the need to share large, complete weight files. The repository provides the necessary scripts, data generation pipelines, and evaluation procedures to support the reproduction and development of instruction-following workflows.
