Unichat-llama3-Chinese is the first Chinese instruction fine-tuning model based on the Meta Llama 3 model released by China Unicom's AI Innovation Center. By training with additional Chinese data, it has achieved high-quality Chinese question and answer capabilities, supporting up to 28K context input and planning to release a version supporting up to 64K. The fine-tuning instruction data has been manually screened to ensure high data quality. Additionally, the model plans to gradually release a 70 billion parameter Chinese fine-tuning version, including long text versions and versions with additional Chinese二次 pre-training.
