Tencent Cloud Opens Yuanbao Search API to External Developers
Tencent Cloud officially opened its Yuanbao Search service to external developers on October 20, featuring a 100-billion-scale index and pricing starting at 14 RMB per thousand calls. This release provides businesses and developers with a powerful, enterprise-grade search infrastructure specifically optimized for large language models and AI agents. It reduces development costs while improving information retrieval accuracy across vertical industries. The service offers three versions—Express, Standard, and Flagship—and supports minute-level updates for news and financial data. It uses an innovative architecture combining inverted and vector indices to achieve low latency and high recall rates.
## BACKGROUND
Large language models often suffer from hallucinations or lack access to real-time, domain-specific information without external search tools. Search APIs designed for AI agents help bridge this gap by fetching, filtering, and structuring web data specifically for model consumption.
