ERNIE-X1

ERNIE-X1 is Baidu's deep-thinking model oriented toward complex reasoning and tool collaboration, designed for workloads that require extended deliberation and coordinated use of external capabilities.

It fits multi-step analysis, decision support, and agent-style flows where the model must reason deeply while invoking tools to retrieve information or execute actions.

ERNIE-X1 shows that high-complexity reasoning and tool collaboration can be delivered at practical deployment cost, supporting the view that relatively low-cost models can still achieve high performance on demanding tasks.
