In contrast with OpenAI, which follows a closed model, DeepSeek’s AI model discloses its full chain of reasoning in an open source model. Altman called DeepSeek’s R1 model “impressive” during a short thread on X.com early last week.

BEIJING (Reuters) -Chinese search engine giant Baidu said on Friday it would make its next-generation artificial intelligence model Ernie open-source from June 30, a major shift in strategy as competition heats up.

Baidu CEO Robin Li, who previously advocated for closed-source models, reportedly acknowledged the potential of open-source development to accelerate AI adoption.

The company, the operator of China’s most popular search engine, announced the plan today. Reuters reported that the initiative centers on an upcoming family of Ernie models dubbed the Ernie 4.5 series. Baidu will start rolling out the LLM series to users in the coming months and plans to open-source its code on June 30.
