Ernie Bot (Chinese: 文心一言, Pinyin: wénxīn yīyán), full name Enhanced Representation through Knowledge Integration,[1] is an artificial intelligence chatbot developed by the Chinese technology company Baidu. Ernie Bot rivals GPT models in Chinese NLP tasks.[2] It is built on the company's ERNIE series of large language models, which have been in development since 2019. The service was first launched for invited testing on March 16, 2023,[3] and was released to the general public on August 31, 2023, after receiving approval from Chinese regulators.[4]
Since its public launch, Ernie Bot has undergone several updates, with newer versions like ERNIE 4.0 and 4.5 released to improve its capabilities. The service has seen rapid user adoption, reportedly reaching over 200 million users by April 2024.[5] It has been integrated into various products, notably powering AI features for the Chinese release of Samsung's Galaxy S24 smartphones.[6]
As a product operating in China, Ernie Bot is subject to the country's censorship regulations. It has been observed to refuse answers to politically sensitive questions, such as those regarding Xi Jinping, the 1989 Tiananmen Square protests and massacre, and other topics deemed taboo by the government.[7][8]

On August 31, 2023, Ernie Bot was released to the public after receiving approval from Chinese regulatory authorities.[13] By December 2023, Baidu announced the service had surpassed 100 million users.[14]
In January 2024, Hong Kong newspaper South China Morning Post reported that a university research lab linked to the People's Liberation Army (PLA) had tested Ernie Bot for military response scenarios. Baidu denied the allegations, stating it had no connection with the academic paper.[15] That same month, Ernie was integrated into Samsung's Galaxy S24 lineup for its launch in China.[16][17]
The user base reportedly grew to 200 million by April 2024 and 300 million by June 2024.[18][19] In September 2024, Baidu changed the chatbot's Chinese name from "Wenxin Yiyan" (文心一言) to "Wenxiaoyan" (文小言) to position it as a search assistant.[20][21]
