We introduceC-Pack, a package of resources that significantly advance the field of general Chinese embeddings.C-Packincludes three critical resources. 1) C-MTEBis a comprehensive benchmark for Chinese text embeddings covering 6 tasks and 35 datasets. 2) C-MTPis a massive text embedding dataset curated from labeled and unlabeled Chinese corpora for training embedding models. 3) C-TEMis a family of embedding models covering multiple sizes. Our models outperform all prior Chinese text embeddings onC-MTEBby up to +10% upon the time of the release. We also integrate and optimize the entire suite of training methods forC-TEM. Along with our resources on general Chinese embedding, we release our data and models for English text embeddings. The English models achieve state-of-the-art performance on the MTEB benchmark; meanwhile, our released English data is 2 times larger than the Chinese data. All these resources are made publicly available athttps://github.com/FlagOpen/FlagEmbedding.
