Cost estimate
ERNIE 4.0 (October 2023) is Baidu's flagship LLM, the model behind 文心一言 (Yiyan) and Wenxin Workshop. Tightly integrated with Baidu Search for grounded answers, Baidu's regulatory licences for Chinese enterprise, and Wenxin's plugin ecosystem. 128K context, multimodal. Pricing is on the high side by 2026 PRC standards — Baidu sells on enterprise-compliance and search-grounding, not raw price.
Editor's verdict
Pick ERNIE for B2B work in mainland China where regulatory licensing matters more than model quality — Baidu has the deepest enterprise compliance story (政務、金融、教育). Search-grounding is genuinely useful when you want fresh facts. For pure capability or price, Doubao, Qwen, and DeepSeek all beat it. Outside mainland China, the case for ERNIE is thin.
