What is ERNIE?
ERNIE is the AI model family developed by Baidu. This website is the official blog where the company publishes release announcements, technical reports, and leaderboard results for its models. The posts describe ERNIE 5.1, a model said to reach leading performance at a fraction of comparable pre-training cost, along with ERNIE 5.0, a 2.4 trillion-parameter unified multimodal model that handles text, image, video, and audio in one framework.
The blog itself does not offer a tool to sign up for or use directly. Its posts report the models' rankings on LMArena, where ERNIE-5.1-Preview was listed as the top Chinese model on the text leaderboard, and ERNIE-Image is described as a text-to-image model with 8B DiT parameters that performs strongly among open-weights models. Access to the models is provided through other Baidu channels, which this page links to as "ERNIE Bot".
