CuteGPT is an open-source conversational language model that supports both Chinese and English, developed by Fudan University KnowledgeWorks Laboratory. It has a scale of 13B (13 billion) parameters. It can perform int8 precision inference on a single 3090 graphics card. CuteGPT base is pre-trained on Chinese-English corpus. Subsequently, it is fine-tuned with conversational instructions to enhance the model's ability to understand instructions. Based on the KW-CuteGPT-7b version, KW-CuteGPT-13b has improved accuracy in knowledge, understanding of complex instructions, ability to comprehend long texts, reasoning ability, faithful question answering, and other capabilities. Currently, the KW-CuteGPT-13b version model outperforms the majority of models of similar scale in certain evaluation tasks.
