百度於2026年5月11日發佈新一代語言模型Ernie5.1，基於2.4萬億參數的Ernie5.0預訓練底座提取。通過“一次性彈性訓練框架”，實現單一訓練優化多尺寸模型，預訓練成本僅爲同類模型的6%。截至5月9日，該模型在Arena Search排行榜以1223分位列全球第四、中國第一，展現高資源利用率與性能平衡。
據媒體報道，百度今年將推出下一代人工智能模型 Ernie5.0。消息人士稱，被稱爲“基礎模型”的Ernie5.0，將在多模態能力方面有重大增強，但沒有具體說明其功能。這一消息正值蘋果公司將其潛在客戶轉向阿里巴巴之後，市場普遍猜測此舉是百度爲了應對局勢的變化，試圖穩住股價和市場地位。
