ERNIE 4.5-300B-A47B

ERNIE 4.5-300B-A47B is a large MoE configuration of Baidu’s ERNIE 4.5, designed to deliver strong accuracy at practical latency by routing each token to a small set of experts (about 47B active parameters). The model is text-in/text-out and instruction-tuned, excels at step-by-step analysis and software engineering tasks, and maintains stable behavior over long prompts. It natively supports function/tool calling for agent workflows, deterministic JSON formatting for integrations, and token streaming for responsive UX, making it a good fit for retrieval-augmented apps and automation pipelines.

In production, it’s available through ERNIE Bot and Qianfan endpoints with selectable context windows and throughput profiles. Teams typically deploy it for high-stakes analysis, document and code understanding at scale, and bilingual Chinese/English assistants that need careful reasoning with consistent formatting and guardrailed behavior.
