OpenCSG is an AI infrastructure company on a mission to empower everyone with large models through open-source, self-hosted platforms with full AI sovereignty. Operating the world's second-largest open-source LLM community with nearly 3 million users, OpenCSG was founded in October 2023 by Chen Ran, former founder and CEO of GitLab China (JiHu).
In an era of AI dependency, true ownership matters. OpenCSG empowers organisations to build, deploy, and control their entire AI stack—models, data, and infrastructure—on their own terms. No vendor lock-in. No data leakage. Full autonomy over your AI future.
