OpenBMB

Open-source efficient AI models and agent infrastructure

OpenBMB is an open-source AI lab and developer community focused on efficient large models, multimodal models, RAG, agents, speech generation, and big-model training. Its GitHub organization lists dozens of repositories, including MiniCPM, MiniCPM-V, VoxCPM, UltraRAG, ChatDev, BMTrain, and EdgeClaw. The group is closely associated with Tsinghua University NLP Lab and ModelBest. Artificial Analysis describes OpenBMB as a China-based lab jointly founded in 2022 by Tsinghua University's NLP Lab and ModelBest Inc. That background explains the project mix: research-heavy model releases, practical demos, efficient training infrastructure, and on-device AI systems. For OpenTools users, OpenBMB matters because MiniCPM and MiniCPM-V fill a different niche than frontier hosted models. The projects target small, capable, open models that can run on phones, edge devices, and local developer hardware. The organization also maintains applied agent projects such as ChatDev and UltraRAG, making it relevant to builders evaluating local AI, multimodal apps, and agent workflows.
