IT Home, October 29 news: Regarding rumors of the resignation of Baidu Group Vice President and Baidu Research Institute Deputy Director Wu Tian, a Baidu public relations manager responded on WeChat Moments, confirming that Wu Tian has ended her tenure at Baidu. She stated that Baidu's technical work is still moving forward.
According to sources close to Baidu, the Ernie model will have new developments to announce next week. IT Home previously reported that the Baidu World 2026 conference is scheduled to be held on November 12. Official information shows that the conference will showcase the technical highlights and application potential of Ernie Unlimited OCR 2, and release the latest upgrade results of Baidu's "chip-cloud-model-agent" full-stack AI.
Public information shows that Wu Tian worked at Baidu for about 20 years. After graduating with a master's degree from Zhejiang University in 2006, she joined Baidu and started in a technical R&D position. She was one of the main early technical leaders of the Ernie Bot model.
In November 2025, Baidu established the Foundation Model R&D Department, and Wu Tian became its head, reporting directly to CEO Robin Li. After that, Baidu's foundation model team underwent organizational adjustments: in May of this year, Wu Tian ceased to be responsible for the foundation model R&D department and was transferred to deputy director of the Baidu Research Institute; in July, large-model technical expert Sun Tianxiang joined Baidu and took over the Foundation Model R&D Department.
Just on October 27, Baidu released and open-sourced Ernie Unlimited OCR 2, expanding the processing limit for document parsing from dozens of pages to any number of pages. The model scored 84.6 and 77.1 overall on MPDocBench, which targets multi-page documents, and MarathonDocBench, which evaluates hundred-page-level ultra-long documents, respectively, achieving end-to-end performance SOTA. Its technical core is the sparse reference sliding window attention mechanism. In hundred-page document scenarios, single-step decoding speed is increased by 7 times and 5.6 times compared with Full Attention and the previous-generation solution, respectively. In actual tests, the model can parse all 7 works in the entire Harry Potter series, totaling more than 3,600 pages, in one go.
