For most everyday users outside China, ChatGPT is the clear winner: it's easier to start using, works on your phone, and handles text, images, voice, and files in one place. ERNIE 4.0 excels for Chinese-speaking users deeply embedded in Baidu's ecosystem, but its geographic restrictions and lack of a mobile app make it impractical for a global audience. The single biggest difference is accessibility: ChatGPT is a one-click web or mobile experience, while ERNIE 4.0 requires a Baidu account, real-name verification, and is effectively blocked outside mainland China.

Common questions

No. ERNIE 4.0 has no mobile app. You can only access it through a web browser on a computer. ChatGPT has official apps for both iPhone and Android.
ChatGPT's free tier is more generous and useful for everyday tasks. ERNIE 4.0's pricing is not clearly published for casual users, and its setup barriers make it impractical for non-developers.
No. ERNIE 4.0 is optimized for Chinese. While it can handle English, its performance and documentation are noticeably weaker. ChatGPT is the better choice for English-language tasks.
ChatGPT, because you can upload files directly in the chat and ask questions in plain English. ERNIE 4.0 can also process files, but the setup is more technical and the interface is less intuitive.
That depends on your location and privacy needs. ERNIE 4.0 requires real-name verification tied to your Baidu account, and data is subject to Chinese regulations. ChatGPT also reviews chats for improvement, so avoid sharing sensitive personal information in either tool.
ChatGPT wins for most people thanks to its mobile app, ease of use, and broad capabilities; ERNIE 4.0 is a niche pick for Chinese-language users inside Baidu's ecosystem.
If you're reading this in English and live outside China, go with ChatGPT — it's free to start, works on your phone, and handles almost any task you throw at it. ERNIE 4.0 is a strong specialist for Chinese users, but for everyday global use, ChatGPT is the simpler, more versatile choice.
