Baidu

basicwidespread

Baidu is China's largest internet search company, developing its own artificial intelligence models and chatbot named ERNIE, primarily for Chinese-speaking users.

In plain terms

Baidu is often referred to as 'the Chinese Google': in China, most people use it to search the internet. The company grew out of search, but today artificial intelligence is one of its main businesses.

ERNIE is the family name of Baidu's language models, and ERNIE Bot (Chinese: Wenxin Yiyan) is the chatbot built on it. It can be considered the Chinese equivalent of ChatGPT: you can ask it questions, have it write text, and make it analyze images. The Chinese application was renamed several times; from 2024, it ran for a while under the name Wenxiaoyan.

It differs from its Western counterparts in that it is primarily strong in Chinese, operates according to Chinese regulations, and is tightly integrated with Baidu's own services: the search engine, maps, cloud, and even the Apollo Go self-driving taxis.

How it works

Baidu trains its ERNIE models on massive amounts of text, images, and other data, primarily in Chinese, partly relying on knowledge from its own search engine.
The finished model generates the answer to your question word by word and may also turn to Baidu's search engine for fresh information.
The average user encounters it in the ERNIE Bot application or embedded in search, while companies can integrate it into their own products via Baidu Cloud (Qianfan platform).
Companies can build agents on top of models, which independently complete multi-step tasks (such as handling customer service inquiries).
In 2025, Baidu made some of its models (the ERNIE 4.5 family) available for free download, so anyone can run them on their own machines. However, the most powerful models remain accessible only through Baidu's services.

An everyday example

You work with a Chinese supplier, and your partner has their emails and offers drafted by ERNIE Bot, just as you would with ChatGPT. If you travel to China, where Western chatbots are largely unavailable, you will likely see this or a similar Chinese assistant on locals' phones.

Who is affected

everyoneBaidu shows that AI development is not solely an American issue, and a world operating under its own rules is being built in China.

A common misconception

MythBaidu is just a search engine, and ERNIE is a quick copy of ChatGPT.

In realityBaidu developed language models well before ChatGPT; the first ERNIE appeared in 2019. The company also operates cloud services, its own AI framework, and self-driving taxis.

Limits and risks

The ERNIE Bot filters content according to Chinese regulations, so it does not answer or answers evasively on politically sensitive questions.
It is expected to be weaker in Hungarian than major Western models, as it was trained primarily on Chinese and English texts.
Outside China, availability and registration may be limited, and your data may be processed on Chinese servers under Chinese law.
Like every language model, this one can make mistakes and assert falsehoods confidently, so verify important answers.

Similar, but not the same

ERNIE Bot – Baidu is the company, ERNIE is the model family, and ERNIE Bot is the chat application built on top of it for users.
DeepSeek – DeepSeek is another young Chinese AI company with its own models; it does not belong to Baidu but is its competitor.
Google – The analogy only suggests that both grew from search engines into major tech companies. The two companies are independent, and Google's search engine is not available in mainland China.

A brief history

Baidu was founded in Beijing in 2000 by Robin Li and Eric Xu. The first ERNIE language model was introduced in 2019, and the ERNIE Bot chatbot in 2023, in response to the success of ChatGPT. In 2025, the company made the ERNIE 4.5 model family freely downloadable.

Where things stand

In China, ERNIE is widely used and has been built into the search engine and the enterprise cloud, but it faces strong domestic competition (DeepSeek, Alibaba, Tencent, ByteDance). Outside China, it remains little known and rarely used.
