On May 9, 2026, Baidu made an official announcement regarding the release of ERNIE Large Model 5.1, a cutting-edge innovation that incorporates "multi-dimensional elastic pre-training" technology. This advancement allows for a significant reduction in the model's total parameters and active parameters, compressing them to roughly one-third and one-half of their original sizes, respectively. Remarkably, the pre-training expenses for this model are a mere 6% of those associated with industry models of comparable scale. This model is now readily accessible on both Baidu's Qianfan Model Plaza and the ERNIE Bot official website, inviting enterprise users and developers to explore and experience its capabilities firsthand.
