FAQ
Where is the vendor of ERNIE (Baidu) based?
Baidu, Inc. is based in China. Regardless of that location, data processing and privacy terms are governed by the vendor's own contract.
How is ERNIE (Baidu) billed?
There are two separate ways in. The Chinese chat assistant at wenxin.baidu.com is in Chinese only and requires a Baidu account. Whether a Chinese mobile number is required for it is not known, and there is no public pricing or membership information. For users outside China, Baidu operates the international Qianfan platform (intl.cloud.baidu.com) with English-language documentation and published prices in US dollars per million tokens. According to the terms of use, the contracting party is Baidu Holdings Limited, and the governing law is Hong Kong law. For users in Germany, only this international API access is practically usable. Chinese consumer prices are presumably billed in yuan but are not publicly listed as a fixed price.
