About

We provide our users with many channels to connect to information and services. In addition to our core web search product, we power several popular community-based products. These include Baidu PostBar, the world’s first and largest Chinese-language query-based searchable online community platform; Baidu Knows, the world’s largest Chinese-language interactive knowledge-sharing platform; and Baidu Encyclopedia, the world’s largest user-generated Chinese-language encyclopedia. Beyond these marquee products we also offer dozens of popular vertical search-based products, such as Maps, Image Search, Video Search, News Search, and many more. We power these through our cutting-edge technology, continually innovating to enhance these services. Over the past few years, rapid mobile adoption has dramatically altered the Internet landscape and opened up tremendous opportunities. As Baidu grows and evolves in the age of mobile, we are taking mobile search to the next stage.

About

ERNIE 5.1 performs strongly across international benchmarks for reasoning, search, knowledge, and agentic tasks, ranking among the top global AI models and leading among Chinese-developed models on multiple leaderboards. The platform introduces a new fully asynchronous reinforcement learning infrastructure that improves training efficiency, scalability, and stability for complex long-horizon AI tasks.
