ERNIE (Baidu)
Baidu's ERNIE model family, available as a Chinese-language chat assistant at wenxin.baidu.com and as a paid API through the Baidu Qianfan platform.
Renamed The ERNIE model line still exists (current generation ERNIE 5.1, released 8 May 2026 per the ERNIE blog; ERNIE 5.0 is what the API offers). The consumer product has been renamed: on 27 Aug 2026 yiyan.baidu.com (formerly ERNIE Bot / Wenxin Yiyan) redirects to wenxin.baidu.com titled '百度文心助手' (Baidu Wenxin Assistant); chat.baidu.com redirects there too. Developer access runs through the Baidu Qianfan platform.
