Baidu's flagship foundation model engineered to match GPT-4 performance across Chinese linguistic nuances and complex reasoning.

Launched at Baidu World 2023, ERNIE 4.0 (Wenxin Yiyan) represents the peak of Baidu's AI stack (built on the proprietary PaddlePaddle deep learning framework). It delivers significant upgrades in four core areas: understanding, generation, reasoning, and memory. The model currently powers Baidu Search and the Wenxin Yiyan chatbot, supporting over 300 million users with 30 percent higher accuracy in multi-step query resolution than its predecessor. It excels at technical tasks (such as Python code generation) and maintains high context retention for enterprise-grade document summarization.
