ERNIE Agent Platform — often referred to as AgentBuilder — is Baidu's answer to the wave of agent-building frameworks. At its core sits the ERNIE large-model family, which handles reasoning, dialogue and content generation; on top of that Baidu layers a visual builder where a creator assembles an agent from a prompt, an optional knowledge base, plugins for external data or actions, and a workflow graph for multi-step logic. The emphasis is on lowering the barrier: a product manager, teacher or support lead can describe the desired behaviour in natural language and iterate on it without writing backend code.
Baidu differentiates the platform through distribution rather than tooling alone. Published agents can be surfaced inside Baidu's own search and assistant ecosystem, which gives creators a potential audience far larger than a stand-alone bot hosted on a private site. The platform also documents commercialization mechanics, letting agent authors connect to service marketplaces and traffic-allocation paths so that a successful agent can become a business rather than just a demo.
Because the platform is delivered primarily in Chinese and is tightly integrated with Baidu Cloud services, it suits teams building for the Chinese market who want a domestic model provider, local compliance posture and native distribution. Evaluation and scoring tools help teams compare prompt variants and knowledge-base configurations before shipping an agent broadly, and templates for common verticals — customer service, education, marketing — shorten time-to-first-agent for teams that are new to the paradigm.
