Architecture and access
The Qianfan product page lists the exact ernie-x1.1-preview endpoint and emphasizes factuality, instruction following, tools, mathematics and code. This entry covers that listed preview service. It does not imply that a downloadable X1.1 checkpoint is available.Baidu Qianfan current model services
Practical use
Practical guidance. Use a task-specific comparison against ERNIE 5.1 before choosing a new reasoning service. Include cases with incorrect premises and missing evidence. Judge whether the final answer identifies those limits, rather than treating a long explanation as a correctness signal.Baidu ERNIE model platform
