About
OpenBMB (Open Lab for Big Model Base), co-founded by Tsinghua NLP researchers and ModelBest Inc. (面壁智能), develops the MiniCPM series of ultra-efficient language models optimized for on-device deployment. MiniCPM4 achieves 3x generation speedup on reasoning tasks, while the multimodal MiniCPM-o 4.5 approaches Gemini 2.5 Flash performance with only 9B parameters. The models are freely available for academic research and commercial use.
