Overview

Overview

OpenBMB, short for OpenLab for Big Model Base, is an open-source initiative dedicated to building a comprehensive library of large-scale pre-trained language models and a comprehensive suite of related tools. The project aims to make it easier than ever for researchers and developers to access, fine-tune, and deploy state-of-the-art large language models.

By focusing on models with hundreds of billions of parameters, OpenBMB accelerates the entire lifecycle—training, fine-tuning, and inference—while dramatically lowering the barrier to entry. This allows individuals and organizations to leverage the power of large models without the need for massive computational resources.

Working hand in hand with developers around the globe, OpenBMB is committed to fostering a thriving open-source community and driving the evolution of the large-model ecosystem. The ultimate vision is to achieve the standardization, popularization, and practical application of large models, bringing them into everyday use and making advanced AI accessible to everyone.
