FlagAI, launched by the Beijing Academy of Artificial Intelligence, is a comprehensive and high-quality open-source project that integrates various mainstream large model algorithm technologies worldwide, as well as multiple large model parallel processing and training acceleration techniques. It supports efficient training and fine-tuning, aiming to lower the barriers to large model development and application while improving development efficiency. FlagAI covers several prominent models in various fields, such as language models like OPT and T5, vision models like ViT and Swin Transformer, and multi-modal models like CLIP. The Academy also continuously contributes the results of projects 'Wudao 2.0' and 'Wudao 3.0' to FlagAI. This project has been incorporated into the Linux Foundation, attracting global research talents for joint innovation and contribution.
