About Yi
01.AI, founded by Kai-Fu Lee, offers the Yi series of open-source large language models, including Yi-1.5, Yi-Coder, and Yi-VL, which are recognized for strong performance in language understanding, reasoning, and coding, particularly in English and Chinese. As of August 2026, the company is transitioning its focus to enterprise-level AI solutions with platforms like TrueNorth (万策) and Wanzhi (万智), while discontinuing its self-serve API platform.
Why We Scored It 6/10
6/10
Yi offers solid open-source models with 8K GitHub stars and inclusion in major AI safety studies, but faces intense competition from stronger players like DeepSeek and established providers. The freemium model with commercial licensing requirements and mid-tier market position limits its impact despite technical competence.
