Open, collaborative research on Large Language Models and Multimodal Foundation Models.

OpenMOSS is a research group led by Prof. Xipeng Qiu, hosted at the Shanghai Innovation Institute (SII) and working in close collaboration with Fudan University and MOSI.AI. We conduct cutting-edge research across the full LLM stack — from model architecture and training to evaluation, interpretability, and real-world applications — with a strong commitment to open and reproducible science.
