Recently, Upstage AI's Deep Expansion Method (DUS) has achieved remarkable results on the SOLAR10.7B large model. By innovatively combining two 7B alpacas, it efficiently integrates infrastructure. In terms of technical implementation, Mistral7B was chosen as the base material, successfully surpassing traditional expansion methods, and the basic model along with the fine-tuned model have been open-sourced. User feedback indicates that this technology performs excellently in practical data processing, bringing new possibilities to the field of deep learning.
