Model family
Yi (01.AI)
Yi is a family of language models from 01.AI, historically influential in China's open-weight model ecosystem.
Origin & context
The Yi family was created by Beijing-based 01.AI (Lingyi Wanwu). The flagship public repository has had limited recent changes, so this record documents a historically significant model family rather than claiming it is the firm's current flagship. Licenses and hosted-service terms vary by release.
