Tonggu is a classical Chinese LLM developed by the Deep Learning and Visual Computing Laboratory (SCUT-DLVCLab) at South China University of Technology. It has strong capabilities in understanding and processing ancient texts. Tonggu uses multi-stage instruction fine-tuning and innovatively proposes a Redundancy-Aware Tuning (RAT) method, which greatly retains the capabilities of the base model while enhancing the performance of downstream tasks.
Figure 1: Training pipeline of TongGu.
Tonggu has surpassed existing models in a wide range of classical Chinese understanding and processing tasks. A comparison with its base model Baichuan2-7B-Chat demonstrates the effectiveness of Tonggu's training process and methods. In the future, Tonggu will continue to update its model and benefit from even more powerful base models.

After extensive data incremental pre-training and instruction fine-tuning, Tonggu has strong capabilities in processing ancient texts, such as punctuation and translation. However, due to limitations in model size and the autoregressive generation paradigm, Tonggu may still generate misleading replies containing factual errors or harmful content that includes bias or discrimination. Please use it cautiously and be aware of discerning such content. Do not spread harmful content generated by Tonggu on the Internet. If any adverse consequences arise, the disseminator shall bear the responsibility.
