 # 欢迎来到洛谷开放平台
 
-:::caution
 
-洛谷开放平台目前处于公测阶段，服务 SLA 和接口稳定性不能保证。费用标准也并非正式商业化价格。
+洛谷开放平台是由国内知名算法社区洛谷推出的技术赋能解决方案，旨在为教育机构、开发者及在线评测系统（OJ）提供一站式题库接入与评测服务。平台依托洛谷十年积累的优质资源，开放其海量公开题库及高并发评测能力，帮助用户快速构建稳定、专业的编程训练环境，显著降低开发运维成本。
 
-:::
+- 海量资源：无缝接入 10,000+ 道精选算法题目（不含RemoteJudge），覆盖主流竞赛考点与教学场景，支持题库实时同步更新。
+- 高速评测：依托高峰期日均处理 200,000+ 评测的分布式系统，提供高效的响应、精准判题服务，免除自建评测机运维压力。
+- 生态兼容：原生支持 HydroOJ、UOJ、SYZOJ 等主流开源 OJ 系统，提供标准化 API 接口与插件化接入方案，确保低代码快速部署。

+
+**Luogu Open Platform** is a technical empowerment solution developed by Luogu, China's premier algorithm community, specifically designed for educational institutions, developers, and Online Judge (OJ) systems. Leveraging a decade of high-quality resources accumulated by Luogu, the platform opens access to its massive public question bank and high-concurrency evaluation capabilities, enabling users to quickly build stable, professional programming training environments while significantly reducing development and operational costs.
+
+- **Extensive Resources**: Seamless integration with 10,000+ curated algorithm problems (excluding RemoteJudge), covering key competition topics and educational scenarios, with real-time question bank synchronization.
+- **High-Speed Judging**: Powered by distributed systems processing over 200,000 submissions daily during peak periods, delivering efficient response times and precise judging services, eliminating the need for self-hosted judging machines.
+- **Ecosystem Compatibility**: Native support for major OJ frameworks including HydroOJ, UOJ, and SYZOJ, featuring standardized API interfaces and plugin-based integration solutions for low-code deployment.

 # 收费标准
 
+:::caution
+
+洛谷开放平台目前处于公测阶段，服务 SLA 和接口稳定性仅能提供尽力而为的支持。费用标准也并非正式商业化价格，如有问题可与我们通过商业邮箱联系。
+
+:::
+
 洛谷开放平台的评测能力服务（RemoteJudge）是付费服务。凡是需要使用这项服务的，都需要收费。
 
 目前仅开放**标准版**一个套餐。以后可能开放更多的套餐。
