Libra-Guard is a safeguard model for Chinese large language models (LLMs). Libra-Guard adopts a two-stage progressive training process: first, it uses scalable synthetic samples for pretraining, then employs high-quality real-world data for fine-tuning, thus maximizing data utilization while reducing reliance on manual annotation. Experiments show that Libra-Guard significantly outperforms similar open-source models (such as ShieldLM) on Libra-Test and is close to advanced commercial models (such as GPT-4o) in multiple tasks, providing stronger support and evaluation tools for Chinese LLM safety governance.
Meanwhile, we have developed the Libra-Guard series of models in different parameter scales based on multiple open-source models. This repository is dedicated to Libra-Guard-Qwen2.5-7B-Instruct.
To run Libra-Guard-Qwen2.5-7B-Instruct, please make sure you meet the above requirements and then execute the following pip commands to install the dependent libraries.
In the multi-scenario evaluation on Libra-Test, the Libra-Guard series outperforms similar open-source models such as ShieldLM, and is on par with advanced commercial models like GPT-4o in multiple tasks. The table below shows a comparison of Libra-Guard-Qwen2.5-7B-Instruct on some key metrics:
Below is a brief example showing how to use Libra-Guard-Qwen2.5-7B-Instruct for inference in order to conduct safety checks or generate responses based on input text.
