Chinese search engine Baidu has launched two new AI models — Ernie 4.5, the latest version of the company’s foundational model first released two years ago, as well as a new reasoning model, Ernie X1.

Baidu Inc. released a new artificial intelligence model that articulates its reasoning, in an apparent bid to regain momentum against up-and-coming rivals like DeepSeek.The Ernie X1 model by China’s internet search leader works similarly to DeepSeek R1 — which shocked Silicon Valley by offering comparable performance to the world’s best chatbots at a fraction of their development cost.

China's Baidu said on Sunday it has launched two new artificial intelligence models, including a new reasoning-focused model that it said rivalled DeepSeek's model, as it vies to stand out in a fiercely competitive AI race.
